OBD (On-Board Diagnostic) systems
Location and pinouts for the Diagnostics Connector
OBD systems are found in most vehicles in use today. OBD is an electronic system designed to control engine functions and diagnose engine problems or component failures, as well as minimize emissions. OBD-II, a new standard introduced in cars built after January 1, 1996, provides almost complete engine control and also monitors parts of the chassis, body and accessory components, as well as the diagnostic control network of the vehicle.
OBD-II equipped vehicles have a connector located in the passenger compartment, usually accessible from the driver’s seat (under the dash above the hood release lever in the Grand Cherokee WJ). A cable is plugged into the OBD-II connector and connected to a scanning tool. This can range from a simple hand-held meter that provides a coded read-out of the various diagnostic functions, up to a large console computer-based unit costing thousands of dollars.
Fault codes usually appear after the “Check Engine” light has come on. The data provided by the OBD-II system can sometimes pinpoint the specific component that has malfunctioned, saving substantial service time and cost. Scanning OBD-II signals can also provide important information when purchasing a used vehicle. Recent introductions of less costly scanning devices have allowed home mechanics and small shops accessibility to OBD-II signals to use them for their own testing and repairs.
Malfunction Indicator Lamp (MIL)
In the Grand Cherokee WJ, the MIL gives an indication to the vehicle operator when the Powertrain Control Module (PCM) has recorded a Diagnostic Trouble Code (DTC) for an On-Board Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is controlled by a transistor on the instrument cluster circuit board based upon cluster programming and electronic messages received by the cluster from the PCM over the Programmable Communications Interface (PCI) data bus.
The MIL bulb is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the bulb will always be off when the ignition switch is in any position except On or Start. The bulb only illuminates when it is provided a path to ground by the instrument cluster transistor.
The instrument cluster will turn on the MIL for the following reasons:
BULB TEST – Each time the ignition switch is turned to the On position the MIL is illuminated for about three seconds as a bulb test.
MIL LAMP-ON MESSAGE – Each time the cluster receives a MIL lamp-on message from the PCM, the indicator will be illuminated. The indicator can be flashed on and off, or illuminated solid, as dictated by the PCM message. For some DTC’s, if a problem does not recur, the PCM will send a lamp-off message automatically. Other DTC’s may require that a fault be repaired and the PCM be reset before a lamp-off message will be sent.
COMMUNICATIONS ERROR – If the cluster receives no lamp-on or lamp-off messages from the PCM for twenty consecutive seconds, the MIL is illuminated by the instrument cluster. The indicator remains controlled and illuminated by the cluster until a valid lamp-on or lamp-off message is received from the PCM.
MIL illumination
In many instances, emissions systems must fail diagnostic tests more than once before the PCM illuminates the MIL. These tests are know as ‘two trip monitors.’ Other tests that turn the MIL lamp on after a single failure are known as ‘one trip monitors.’ A trip is defined as ‘start the vehicle and operate it to meet the criteria necessary to run the given monitor.’
Certain conditions such as a loose or missing gas cap, poor fuel quality, etc. may illuminate the light after engine start. The vehicle should be serviced if the light stays on through several typical driving cycles. In most situations, the vehicle will drive normally and will not require towing.
Prolonged driving with the “Malfunction Indicator Light” or “Check Engine” light on could cause further damage to the emission control system. It could also affect fuel economy and driveability. The vehicle must be repaired before any emissions test can be performed.
If the light is flashing, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
Retrieving codes:
Turn the ignition key until the digital odometer displays, repeat three times in succession and then back to “On” (On/Off, On/Off, On/Off, On). At the fourth “On” the odometer will be replaced with codes. If no codes are present then “Done” will appear.
Erasing codes:
After three good trips the MIL is extinguished and the Task Manager automatically switches the trip counter to a warm-up cycle counter. DTCs are automatically erased following 40 warm-up cycles if the component does not fail again.
DTCs can be erased anytime with a DRB III. Erasing the DTC with the DRB III erases all OBD II information. The DRB III automatically displays a warning that erasing the DTC will also erase all OBD II monitor data. This includes all counter information for warm-up cycles, trips and Freeze Frame.

Follow all appropriate diagnostics for the fault that is present. Prior to replacing parts, check all connectors between the speed control switch and the PCM for moisture Internally the PCM uses the same A/D (analog to digital) converter for TPS voltage as it does for the speed control switch sense. If the v-37 circuit has voltage bleed over from another source, a code of TPS Shorted to voltage may be set in the PCM. The DN model equipped with rear heat option, has an external water pump to circulate coolant to the rear heater. If you find coolant in the bulkhead connector, the likely cause would be a leaking coolant pump. Pump should be replaced if found leaking. If the code sets when the A/C is turned on go right to the bulk head connector and check for moisture. Check for a shorted clock spring causing the speed control 5 volt feed to be shorted to power. |

If ORVO is working as designed insure that the vehicle owner is not overfilling the fuel tank. |
| P0442 (M) | Evaporative Emission Control System Leak Detected (medium leak) | A 0.040 leak has been detected in the evaporative system. (A faulty gas cap may cause this code). Also see TSB 25-001-02A. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system. |

Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve.

This may occur after driving the vehicle in rain or by washing the vehicle. Also if the rear heater water pump is leaking, as on a DN model with rear heat, the C200 could be contaminated with anti-freeze. Once connector is cleaned from antifreeze contamination, review water pump for potential leak and repair as necessary. If there is water intrusion into the connector, dry the connector and repair area that is allowing water into the connector. This area is the source of many speed control complaints.
