BRAKE ROUGHNESS OR PEDAL PULSATION WHEN THE BRAKES ARE APPLIEDDate: 08/98Bulletin # 050398 Model year(s): 1999 Description: Superceded by 0500302B dated 05/13/02). INTERMITTENT OPERATION OF THE POWER DOOR LOCKS, RKE AND POWER WINDOWSDate: 08/30/98Bulletin # 084798 Model year(s): 1999 Description: Intermittent and erratic operation of the power door locks, Remote Keyless Entry (RKE) and Power Windows. This can be the result of a communication error in the Door Switch Module located in the passengers’ door. Revised programming in the Body Control Module has been developed to address this issue. Details: Due to the intermittent nature of this condition, diagnosis may be difficult. If customers complain of intermittent or erratic operation of any of the systems listed above, perform the Repair Procedure. OXYGEN SENSOR OPERATING DIFFERENCESDate: 09/25/98Bulletin # 183198 Model year(s): 1999 Description: Oxygen sensor operating differences. NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A 4.7L ENGINE. Details: To enhance the idle quality of the 4.71- engine, the 02 sensor will be biased rich when the engine is at idle and the transmission is in Park or Neutral. The upstream goal voltage during this time will be between 0.7 and 0.85 volts. The 02 sensor should not be condemned for slow or no switching while at idle and in Park or Neutral. 02 switching tests should be performed off idle in any gear, or at idle in a forward gear range. During these conditions, the 02 sensor goal voltage will be in the normal (0.5 volt) range. FLASH PROGRAMMING FAILURE RECOVERYDate: 09/25/98Bulletin # 183298 Model year(s): 1999 Description: Flash programming failure recovery. Details: Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment may lock up during the procedure. FLUID LEVEL INSPECTION 45RFE TRANSMISSIONDate: 10/16/98Bulletin # 211398 Model year(s): 1999 Description: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A 45RFE TRANSMISSION. The 45RFE transmission is newly introduced for the 1999 model year and has some unique service differences compared with its predecessors. Following are some items to consider during service. Details: Fluid Level Inspection: NOTE: WHEN COLD (BELOW 10° C {50° F}) THE FLUID LEVEL WILL NOT REGISTER ON THE DIPSTICKAccurate fluid level is difficult to determine cold. Initially add only 5 quarts of fluid during the refill procedure. This amount will allow the transmission to operate until warm and once the fluid temperature is known, the final amount can be added without overfilling the transmission. Additionally, during this procedure pressure switch and/or loss of prime DTC’s may be set. If they are, erase them using the DRB III® before returning the vehicle to the customer. INSPECTION MAINTENANCE TESTING – OBD II “CARB” READINESSDate: 10/98 Bulletin # 250298 Model year(s): 1999 Description: I/M (Inspection Maintenance) testing – OBD II “CARB” readiness monitor information. Details: Some states that require I/M inspections are beginning to include OBD II “CARB” Readiness as a prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or more of the Readiness monitors read “NO” or in other words the OBD II monitors have not run their tests. It is important to understand that the MIL will not be illuminated because OBD Readiness reads “NO”. MIL illumination happens when an actual malfunction or failure of a monitored emissions system occurs. It is possible to have MIL illumination for a detected failure while at the same time having a “NO” for an OBO Readiness monitor. NOTE: MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS BULLETIN. OBD Readiness that reads “NO” can be caused by the following: PCM reprogramming, PCM replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items occur before an I/M test, a good chance exists that one or more of the monitors will read “NO” for OBD Readiness. REVISED FRONT BAND ADJUSTMENT FOR 42RE TRANSMISSIONSDate: 12/04/98Bulletin # 211698 Model year(s): 1999 Description: Revised front band adjustment for 42RE transmissions.

Parts required: VEHICLE START AND STALL OR VEHICLE NO-STARTDate: 05/21/99Bulletin # 081499 Model year(s): 1999-2000 Description: Conditions with vehicle start and stall or vehicle no-start. A vehicle start and stall or no-start condition may exist from the interaction between a SKIS key and a Mobil Speedpass®. This condition occurs during cranking, when the Mobil Speedpass cylinder is held immediately adjacent to the key being used to start the vehicle. Details: NOTE: THIS CONDITION DOES NOT OCCUR BY THE MOBIL SPEEDPASS® CYLINDER SIMPLY BEING ATTACHED TO THE SAME KEY RING. This bulletin applies to vehicles equipped with a sentry key immobilizer system (SKIS). If a stall or no-start condition exists due to this problem, the Vehicle Theft Security System (VTSS) indicator light will flash and the vehicle will stall after 2 seconds of running. The’Sentry key Immobilizer Module (SKIM) will set either the “Transponder Comm Failure”, or a “Transponder CRC Failure” fault code. To diagnosis this condition, remove the Mobil Speedpasse from the key ring and attempt to start the vehicle. If the vehicle starts and remains running, SKIS key interaction with the Mobil Speedpasse was the cause. This condition will not cause a vehicle to stall after it has been running normally. If a start and stall or no-start condition continues once the Mobil Speedpass® is removed, continue with the appropriate diagnostic procedures. In cases where SKIS key interaction with the Mobil Speedpasse is causing the condition, instruct the customer to slightly separate the SKIS key and Mobil Speedpass® when starting the vehicle. There are no long-term adverse effects on any of the components once the Mobil Speedpasse is removed from the SKIS operating area. DIAGNOSTIC TROUBLE CODES CAUSED BY OPEN FUSEDate: 05/21/99Bulletin # 180999 Model year(s): 1999 Description: Information pertaining to common diagnostic trouble codes caused by an open fuse. Details: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. DOOR WEATHER SEAL RETENTIONDate: 05/21/99Bulletin # 231499 Model year(s): 1999 Description: The door weather seals may not fit the door flange properly. This can cause loose or sagging door seals and the associated wind and water leaks. Details: This bulletin involves installing foam tape on door seal flange to assure proper sealing and retention. Inspect the door weather seals. If the seals are loose or sagging and do not fit tightly on the flange, perform the Repair Procedure. Parts required: ROOF RACK CROSS BAR SHIPPING LOCATIONDate: 05/21/99Bulletin # 231799 Model year(s): 1999 Description: Information pertaining to roof rack cross bar shipping location. Details: The rear cross bar on the roof rack is currently being moved to the full forward location prior to shipment from the assembly plant. This is being done to prevent damage to the cross bar when vehicles are loaded onto transports. The cross bar must be moved back to the rear most position on the roof rack rails prior to delivery to customers. Leaving the cross bar in the forward position can cause excessive air turbulence and the associated wind noise. NOISY FRONT PROPELLER SHAFTDate: 05/28/99 Bulletin # 030399 Model year(s): 1999 Description: Noisy front propeller shaft rear constant velocity joint. Details: Applies to models built prior to March 14, 1999. While driving, a noise may be noticed coming from the front propeller shaft. The noise may sound like popping, snapping and/or grinding. A driveline vibration may also be noticed. Closer inspection of the front propeller shaft may reveal a loss of lubricant from the rear constant velocity (CV) joint. The loss of lubricant may be due to a torn CV joint boot. The condition may be the result of an interface fit between the back of the rear CV joint and the end of the transfer case front output shaft. This interface fit may cause the vent hole on the back of the rear CV joint to become blocked (sealed over). If the vent on the joint becomes blocked, it may cause pressure to build within the joint which may result in damage to boot of the rear CV joint. Parts required: SHUDDER NOISE IN TRANSFER CASEDate: 06/04/99Bulletin # 210999 (supercedes 211798 dated 12/11/98) Model year(s): 1999 Description: This bulletin involves a new transfer case fluid, a revised Repair Procedure, and a change to the Maintenance Schedules “A” and “B”. VEHICLES BUILT ON OR AFTER APRIL 9, 1999 HAVE THE NEW TRANSFER CASE FLUID ALREADY INSTALLED IN THE NV 247 TRANSFER CASE FROM THE ASSEMBLY PLANT. A shudder and/or low pitched grunting noise may be present in the transfer- case. The condition is a slip/stick condition in the progressive coupling assembly. The condition may be present at slow speeds, and/or during tight steering maneuvers such as parking or backing out of a driveway. Details: The new transfer case fluid has several different characteristics from that of ATF-4. Some of those characteristics are: a yellow color, a slightly higher viscosity, and a sweet (new vinyl like) odor. These characteristics may vary depending on how well the transfer case was drained prior to refill. THE RECOMMENDED MAINTENANCE INTERVAL FOR SCHEDULED SERVICE TO THE TRANSFER CASE FLUID IS CHANGED. FOR SCHEDULE “A” (FOR NORMAL OPERATING CONDITIONS), IT IS RECOMMENDED THAT THE TRANSFER CASE FLUID BE DRAINED AND REFILLED EVERY 22,550 MILES OR 18 MONTHS. FOR SCHEDULE “B” (OTHER THAN NORMAL OPERATING CONDITIONS) IT IS RECOMMENDED THAT THE TRANSFER CASE FLUID BE DRAINED AND REFILLED EVERY 21,000 MILES. Parts required:

There are no long-term adverse effects on any of the components once the Mobil Speedpasse is removed from the SKIS operating area. TRANSMISSION FLUID LEVEL INSPECTION PROCEDURE/SERVICE CAUTIONSDate: 07/23/99 Bulletin # 211199 (supercedes 211398 dated October 16, 1998) Model year(s): 1999-2000 Description: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A 45RFE TRANSMISSION. The 45RFE transmission, newly introduced in the 1999 model year on Grand Cherokee models and for 2000 Dakota and Durango models, has some unique service features compared with its predecessors. Details: The following are some items to consider during service: Fluid/Filter Replacement: FRONT END ALIGNMENT – ADJUSTABLE / OFFSET BALL JOINTSDate: 08/20/99 Bulletin # 021299 Model year(s): 1999-2000 Description: Front end alignment – adjustable / offset ball joints. Details: This bulletin involves installing offset ball joints to allow adjustments to camber, which were not previously possible on XJ, TJ and ZJ models and to camber and caster which were not possible on WJ models. This TSB releases new offset ball joints which provide the capability to make front-end alignment adjustments to camber and caster. Camber adjustments and caster adjustments on some models are fixed and built into the front axle. Caster adjustments could be made in the past on TJ, XJ and ZJ models. These parts are only to be used in situations where a slight lead or drift to one side of the road or another is occurring with no driver input or where a customer indicates that constant driver input is required to maintain straight ahead steering. These parts will not effect situations where a lead or drift condition is present only under braking. Parts required: AXLE DIAGNOSISDate: 09/24/99 Bulletin # 030599 Model year(s): 1999-2000 Description: Diagnosis of the vehicle axle Details: A sound may appear to be coming from the general area of the vehicle axle(s). The sound may be described as a growl, howl, or a whine. They may occur at different vehicle or engine speeds. They may also occur during different axle loading conditions i.e light driving, heavy driving, float, cruise or coast. A correct and thorough diagnosis of the axle condition is perhaps the most important tool that the technician has in effecting a successful axle service. Because the transmission of an axle-like sound may be due to vehicle components other than the axle, a good diagnostic procedure is necessary in determining if the condition can be corrected by service to the internal axle components. Proper diagnosis may lead the technician to vehicle components other than the axle. 45RFE TRANSMISSION SHIFT QUALITY IMPROVEMENTS 45RFE TRANSMISSION SHIFT QUALITY IMPROVEMENTSDate: 09/03/99 Bulletin # 211299 Model year(s): 1999-2000 Description: (superceded by 210900 dated 09/15/00) DRIVE LEARN PROCEDURES FOR 45RFE TRANSMISSIONSDate: 09/03/99 Bulletin # 211399 Model year(s): 1999-2000 Description: 45RFE drive learn procedures for 45RFE transmissions. Details: The 45RFE transmission adapts to its mechanical tolerances by learning the clutch volume indexes (CVI’s) as well as the duty cycle and other parameters that control shift quality. Performing a Quick Learn will simply reset all transmission adaptive values to factory preset values and it will exercise the transmission clutches to learn an approximate value for the clutch CVI’s. Quick Learn should not be used as a remedy for shift quality complaints. Quick Learn resets more than 70 learn parameters to their preset values and will require-them to be relearned. Quick Learn should only be used when a transmission has be replaced or overhauled, or when the Transmission Control Module has been replaced or flashed. Once Quick Learn is performed, an initial drive evaluation should be performed to determine if the transmission is shifting smoothly. VERIFY THAT ALL APPLICABLE TECHNICAL SERVICE BULLETINS FOR SHIFT QUALITY HAVE BEEN PERFORMED PRIOR TO PERFORMING THE DRIVE LEARN PROCEDURE. FUEL SYSTEM PRESSURE DIAGNOSTIC PROCEDURESDate: 10/08/99 Bulletin # 140599 Model year(s): 1999-2000 Description: Fuel system pressure diagnostic procedures that may be used to determine the cause of a loss of fuel system pressure. Details: A loss of pressure in the fuel system may occur at any rate depending upon the cause of the fuel leakage. Because the rate of fuel pressure loss may vary between vehicles, the symptoms of this condition may be different from one vehicle to another. The condition may be more noticeable when the vehicle engine is started. Low or no fuel pressure may cause, a long crank time, a start and stall, an initial sag or hesitation, and other engine performance conditions. The condition may vary depending upon engine temperature and/or ambient temperature.

Details: A customer may complain that the vehicle engine is operating at higher than normal engine temperatures. The condition may be caused by a delay in the start of the hydraulic cooling fan. The ambient temperature and how the vehicle is used may impact the amount of engine temperature increase. USING SUPPLEMENTAL OIL ADDITIVE TREATMENTSDate: 05/04/01 Bulletin # 0900301 Model Year(s): 1999-2003 Description: NOTE: THIS BULLETIN APPLIES TO ALL DAIMLERCHRYSLER MODELS/ENGINES BUILT BEFORE AND AFTER THE 2001 MODEL YEAR. This bulletin reinforces a requirement to cease the current practice of using supplemental oil additive treatments in all DaimlerChrysler engines. Details: Engine oil additives/supplements (EOS) should not be used to enhance engine oil performance. Engine oil additives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for engine durability and can degrade emission components. Additives can contain undesirable materials that harm the long term durability of engines by: 1. Doubling the level of Phosphorus in the engine oil. The ILSAC (International Lubricant Standard Approval Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10% Phosphorus to protect the vehicles emissions performance. Addition of engine oil additives/supplements can poison, from the added sulfur and phosphorus, catalysts and hinder efforts to guarantee our emissions performance to 80,000 miles and newrequirements of 150,000 miles. 2. Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements of the specified viscosity grade. 3. Creating potential for an undesirable additive compatibility interaction in the engine crankcase. Generally it is not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of low temperature engine failures caused by additive package incompatibility with such mixtures. LONGER THAN NORMAL ENGINE CRANK TIME PRIOR TO ENGINE STARTDate: 03/16/01 Bulletin # 1400201 (supercedes 140600 dated 09/15/00) Model year(s): 1999-2001 Description: This bulletin involves the repair of the fuel pump module. The customer may experience a longer than normal engine cranking time prior to engine start. This condition may be caused by fuel pressure loss due to a worn sealing ring within the fuel module. NOTE: QUALITY ANALYSIS HAS REVEALED THAT A WORN SEALING RING IS THE PRIMARY REASON WHY THE FUEL MODULE IS REPLACED FOR FUEL PRESSURE LEAK DOWN. IT IS RECOMMENDED THAT THE SEALING RING BE REPLACED BEFORE A FUEL MODULE ASSEMBLY REPLACEMENT IS ATTEMPTED. Details:1. Start and run the engine. Verify normal fuel system pressure of 339 kPa +/- 34 kPa (49.2 psi +/- 5 psi). 2. Stop the engine. Verify that the fuel system pressure does not fall below 207 kPa (30 psi) in less than five (5) minutes. 3. If the fuel pressure does not fall below 207 kPa (30 psi) in less than five (5) minutes,then the long crank time may not be due to the fuel system. Further diagnosis must be made to the entire engine system. 4. If fuel pressure does fall below 207 kPa (30 psi) in less than five (5) minutes, then refer to TSB 14-05-99 for additional fuel system diagnostic assistance. 5. If diagnosis determines that the cause of the fuel system pressure loss is due to the fuel pump module, then inspect the fuel pump module part number label for its assembly build date code (Julian date). The part number label is affixed to the fuel pump module wire harness (pigtail), near the electrical connector to the body wire harness. 6. Inspect the bottom row of numbers on the fuel module label and locate the module build date code. Determine the date of build (Julian date) for the fuel module assembly. The first two numbers in the date code indicate the calendar year (1998 = 98, 1999 = 99, 2000 = 00, 2001 = 01), and the remaining three numbers in the code (1 to 365) represent the day of the calendar year (Figure 1). 7. If the module part label indicates that the fuel module assembly was built on or before November 04, 1999 (Julian date of 99308), then a spacer must be used with the sealing ring. The split washer in the repair kit is used as the sealing ring spacer. NOTE: FAILURE TO USE THE SPLIT WASHER, AS A SPACER FOR THE SEALING RING (WHEN REQUIRED), MAY CAUSE EXCESSIVE MOVEMENT AND DAMAGE TO THE SEALING RING. 8. If the module part label indicates that the fuel module assembly was built after November 04, 1999 (Julian date of 99308), then a spacer must NOT be used with the sealing ring. The split washer in the repair kit can be discarded. NOTE: SOME REPLACEMENT FUEL PUMP MODULES, BUILT AFTER NOVEMBER 04, 1999 (DATE CODE 99308), HAVE BEEN USED TO REPLACE FUEL MODULES BUILT PRIOR TO NOV. 04, 1999. IT IS IMPORTANT THAT PRIOR TO EACH REPAIR THE MODULE DATE CODE BE PROPERLY DETERMINED. Parts required: LEAK DETECTION PUMP OPERATION AND DIAGNOSISDate: 03/30/01 Bulletin # 1800901 Model Year(s): 2001 Description: Operation and diagnostics for the EVAP system’s Leak Detection Pump. Details: Leak Detection Pump Operation and Diagnosis Booklet (Publication No. 81-170-00006) is being provided with this Technical Service Bulletin to aid in the diagnosis and repair of the evaporative emission systems on today’s vehicles.

ROUGH IDLE AT COLD TEMPERATURES 4.0LDate: 04/20/01 Bulletin # 1801001 Model Year(s): 2001 Description: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 4.0L (ERH) ENGINE BUILT PRIOR TO APRIL 30, 2001 AND CALIBRATION LEVEL PRIOR TO (LESS OR LOWER THAN) THOSE LISTED BELOW. This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software (WJ/TJ — calibration level 01Cal14C, XJ — calibration level 15B.) Details: Some vehicle engines may exhibit a rough idle and/or MIL light “on” condition upon initial start-up after a cold soak when temperatures are below 50°F (10°C). Using the Diagnostic Scan Tool (DRBIII) with the appropriate Diagnostic Procedures, verify all engine/transmission systems are functioning as designed. If other DiagnosticTrouble Codes are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If the only condition seen is the rough idle and/or MIL light “on” condition upon initial start-up after a cold soak when temperatures are below 50°F (10°C) perform the Repair Procedure. AIRBAG / CLOCK SPRING SERVICEDate: 05/25/01 Bulletin # 0801001 Model Year(s): 1999-2002 Description: Air bag / clock spring service for various models including 1999-2002 Grand Cherokee. Details: When servicing any airbag system, it is essential to follow the proper Service Manual and/or Diagnostic Manual procedures for diagnosing, testing, and replacement of any component. When diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII, the use of the Airbag Load Tool (special tool 8310 and 8443) is required. The Airbag Load Tool, used in conjunction with the DRBIII are used to isolate and test components and wiring for failure. Only replace the component or wiring that has failed. This will reduce unnecessary cost to the customer. NOTE: Airbag replacement is not required every time it is removed or when another component has failed. Use of the DRBIII and Airbag Load Tool will determine if the airbag has failed and replacement is needed. Recent analysis of returned clock springs have indicated that prior service may have contributed to the clock spring’s failure. Do not use silicone or other lubricants on or near the clock spring. Lubricants are often used in the clock spring area of the steering column to eliminate noise. Lubricants may have an adverse effect on the clock spring. Clock spring centering – Any repair that may disrupt the positioning of the steering wheel with the front wheels will require that the clock spring be centered. This includes clock spring replacement, steering column service, HVAC service, steering gear service, and front suspension crossmember service. Refer to the appropriate Service Manual for the clock spring centering procedure. COOLER OR WARMER THAN DESIRED AIR TEMPERATURESDate: 05/18/01 Bulletin # 2400701 Model year(s): 1999-2001 Description: A customer may experience colder or warmer than desired air temperatures coming from the vehicle HVAC system vents. This change in air temperature may occur gradually over time and only on vehicles equipped with the Automatic Zone Control (AZC) HVAC system. The air from the driver side HVAC vents will tend to increase in temperature, with this condition being more noticable when outside ambient air temperatures are in the 16°C to 27°C (60°F to 80°F) range. The air from the front passenger HVAC vents will tend to decrease in temperature, with this condition being more noticeable when ambient temperatures are in the -7°C to 4°C (20°F to 40°F) range. Details: This bulletin involves the replacement of the Automatic Zone Control assembly. Since the condition occurs gradually over time, the technician may not be able to readily verify the condition. If the HVAC system appears to be operating correctly and the customer complains of the above condition, then perform the Repair Procedure. Parts required: TROUBLE CODES CAUSED BY AN EVAPORATIVE SYSTEM LEAKDate: 05/11/01 Bulletin # 2500401 Model year(s): 1999-2001 Description: Additional diagnostic for diagnostic trouble codes caused by an Evaporative System leak. This bulletin involves information which may be of assistance when diagnosing the vehicle evaporative system for a possible leak source and its cause. Details: DTC P0442, P0455 or P0456 are all diagnostic codes indicating a leak has been detected in the EVAP system. The bulletin points out that, while most leaks will be external such as a loose gas cap or damaged hose, internal leaks also are possible. The most likely source of an internal leak is the Duty Cycle Purge valve (DCP). This valve could be stuck open due to corrosion, dirt from outside or debris from inside the system, such as charcoal from the vapor canister. The DCP valve is tested by on-board diagnostics only after the Purge Flow Monitor is passed; if that monitor fails, the DCP valve will not be tested. The bulletin offers helpful tips for troubleshooting and understanding the logic of the EVAP diagnostic routine AUTOMATIC TRANSMISSION FLUID USAGE ATF+4®Date: 06/29/01 Bulletin # 2100601 (supercedes 211699 10/22/99) Model year(s): 1999-2002 Description: Information pertaining to automatic transmission fluid usage ATF+4®.

USING SUPPLEMENTAL OIL ADDITIVE TREATMENTS Date: 05/04/01 Bulletin # 0900301 Model Year(s): 1999-2003 Description: NOTE: THIS BULLETIN APPLIES TO ALL DAIMLERCHRYSLER MODELS/ENGINES BUILT BEFORE AND AFTER THE 2001 MODEL YEAR. This bulletin reinforces a requirement to cease the current practice of using supplemental oil additive treatments in all DaimlerChrysler engines. Details: Engine oil additives/supplements (EOS) should not be used to enhance engine oil performance. Engine oil additives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for engine durability and can degrade emission components. Additives can contain undesirable materials that harm the long term durability of engines by: 1. Doubling the level of Phosphorus in the engine oil. The ILSAC (International Lubricant Standard Approval Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10% Phosphorus to protect the vehicles emissions performance. Addition of engine oil additives/supplements can poison, from the added sulfur and phosphorus, catalysts and hinder efforts to guarantee our emissions performance to 80,000 miles and newrequirements of 150,000 miles. 2. Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements of the specified viscosity grade. 3. Creating potential for an undesirable additive compatibility interaction in the engine crankcase. Generally it is not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of low temperature engine failures caused by additive package incompatibility with such mixtures.

Repair procedure: ROUGH IDLE AFTER RESTART AFTER HOT SOAKDate: 9/06/02 Bulletin # 1802702 Model Year(s): 1999-2002 Description: NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH THE 4.0L ENGINE. This bulletin involves the installation of a fuel injector insulator sleeve. Details: Customers may complain of rough idle for 20-30 seconds after a 10-20 minute soak in hot ambient conditions, around 32 C (90єF), after short city driving trips. This condition can be aggravated by high ethanol content in the fuel the customer is using. This condition is caused by heat from the exhaust manifold that, during shut down, migrates to the area around injector #3 and causes a vapor to form in the injector. This in turn causes a misfire of cylinder #3. The insulator sleeve lowers the injector #3 temperature to a point below which the fuel will vaporize. If vehicle exhibits a rough idle and sets code P0303 (Cylinder #3 Misfire), then install the injector insulator per the repair procedure Repair procedure: 2. Install one sleeve around injector #3, with the slit on the upward facing side of the injector. Install the other sleeve with the slit on the downward facing side of the injector. 3. Confirm sleeve is flush to intake manifold surface around injector. 4. Check injector #3 wire and ensure that the injector is rotated to a 2 o’clock position (from driver’s side of vehicle).

POP/TICK SOUND IN STEERING WHEEL AREADate: 2/07/03 Bulletin # 1900103 Model Year(s): 2002-2003 Description: NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH TILT STEERING (SALES CODE SUA) AND BUILT ON OR AFTER JANUARY 14, 2002. FOR VEHICLES BUILT ON OR BEFORE JANUARY 13, 2002 REFER TO SERVICE BULLETIN 19-008-01 DATED NOVEMBER 23, 2001. A pop/tick sound may be heard coming from the steering wheel area while the vehicle is in motion. The sound is associated with input from the road surface. It may be difficult to readily repeat the sound once it has occurred until additional road input is experienced, such as driving over an expansion strip. Details: This bulletin involves replacing the spring washer in the steering column and upper tilt head housing assembly and on WJ/WG – vehicles, replacing the jacket clamp bracket TIRE PRESSURE MONITOR SYSTEM PERFORMANCE AFFECTED WHEN LARGE AMBIENT TEMPERATURE CHANGES OCCURDate: 2/07/03 Bulletin # 2200103 Model Year(s): 2002-2004 Description: Some 2002 to 2004 Grand Cherokee vehicles incorporate an optional Tire Pressure Monitor (TPM) System that displays the actual tire pressure for all four (4) road tires and will also display the tire pressure for certain full size spare tires, if equipped. The Electronic Vehicle Information Center (EVIC) is used to display TPM System messages. The TPM System message “Low Tire Pressure” will be displayed on the EVIC when at least of one of the tire pressure sensor(s) detects a tire pressure of 25 PSI or less. The “Low Tire Pressure” message is designed to turn off when a tire pressure of 28 PSI or higher is detected. Tire pressure can drop approximately 1 PSI for every 10 F drop in ambient temperature. In colder climates, significant changes in ambient temperature can influence tire pressure readings. For example, a vehicle with tire pressures initially set at 29 PSI in a 70 F heated garage and then allowed to set long enough outside in 20 F ambient temperature, can experience a drop of 5 PSI in tire pressure due only to the change in ambient temperature. The tire pressure would now read approximately 24 PSI. In this instance, the TPM System will sense that tire pressure is below the 25 PSI threshold and will display the “Low Tire Pressure” message. Details: To reduce the occurrence of the above condition and any unnecessary customer concern about the performance of their vehicle TPM System, dealers servicing Grand Cherokee vehicles with the optional TPM System should ensure that tire pressures are set to the recommended tire pressure. The recommended tire pressure can be found on the tire pressure label that is located on rear face of the driver’s door. SETTING TIRE PRESSURES AT THE RECOMMENDED TIRE PRESSURE (LABEL PRESSURE) WILL MINIMIZE THE POSSIBILITY OF TRIGGERING LOW (OR HIGH) TIRE PRESSURE MESSAGES BY THE TPM SYSTEM. CHECK AIR PRESSURE IN TIRES WITH AN ACCURATE TIRE PRESSURE GAUGE. DO NOT USE THE TIRE PRESSURE DISPLAY ON THE EVIC TO ADJUST TIRE PRESSURE. When reading actual tire pressures know that cold inflation pressure is defined as the air pressure inside the tire(s) after the vehicle has not been driven for at least a three (3) hour period, or the air pressure inside the tire(s) when the vehicle has not been driven more than one (1) mile after the minimum three (3) hour non-driving period has occurred.

DUTY CYCLE PURGE SOLENOID CAUSES A TICKING-LIKE SOUND FROM ENGINE COMPARTMENTDate: 2/21/03 Bulletin # 2500103 Model Year(s): 2002-2004 Description: This bulletin involves isolating the Duty Cycle Purge (DCP) solenoid from the vehicle body. Details: The customer while sitting in the passenger compartment may notice a ticking-like sound when the engine is idling. The sound may be more noticeable in colder ambient temperatures. Mechanical contact between the DCP solenoid and the body of the vehicle may be the cause of the ticking-like sound. The ticking-like sound may also be described as a tapping or clicking-like sound. The sound may appear to be similar to the sound produced by a worn or loose engine valve train component, such as a valve lifter. Diagnosis: 1. Use the Actuator Mode on the DRB III® scan tool to cycle the DCP solenoid. Navigate through the following menus on the DRB III®: Main Menu, Stand-Alone Menu, 1998–2003 Diagnostic Menu, Select System Menu – Engine, Select Function Menu, Actuators Menu. Scroll over to page 4 of 5 in the Actuators Menu to find the Evap Purge Solenoid. 2. Verify the customer complaint. Sit in the driver seat with all doors closed. The fan on the DRB III® can be quieted by temporarily covering the fan exhaust port with your hand. Actuate the DCP solenoid. 3. If the ticking-like sound is present, remove the DCP solenoid from its mounting bracket but keep the evaporative and electrical connections connected to the DCP solenoid. Allow the DCP solenoid to hang in place free of contact with the rest of the vehicle. 4. Actuate the DCP solenoid with the DRB III®. If the ticking-like sound is now diminished in sound level or is no longer present, then perform the Repair Procedure. 5.
