1. Understanding OBD2 Systems in Your 2006 Jeep Grand Cherokee
OBD2 (On-Board Diagnostics II) systems are standard in vehicles manufactured after 1996, including the 2006 Jeep Grand Cherokee. These systems monitor various engine functions and diagnose problems or component failures, helping to minimize emissions. Let’s explore what you need to know.
1.1 How OBD2 Systems Work
OBD2 systems in the 2006 Jeep Grand Cherokee work by monitoring the performance of key components, including the engine, transmission, and emissions systems. When a problem is detected, the system generates a Diagnostic Trouble Code (DTC) and stores it in the vehicle’s computer.
1.2 Accessing the OBD2 Connector
The OBD2 connector is typically located in the passenger compartment, accessible from the driver’s seat. In the Grand Cherokee WJ, you can find it under the dash, above the hood release lever. This connector allows you to plug in a scanning tool to read the stored DTCs.
1.3 Scanning Tools: From Basic to Advanced
Scanning tools range from simple handheld meters to sophisticated computer-based units. Basic tools provide a coded read-out of diagnostic functions, while advanced tools offer detailed analysis and troubleshooting steps. Recent advancements have made these tools more accessible to home mechanics and small shops.
2. Decoding the Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL), often called the “Check Engine” light, alerts the driver when the Powertrain Control Module (PCM) has recorded a DTC for an emissions-related circuit or component malfunction.
2.1 How the MIL Works
The MIL is controlled by a transistor on the instrument cluster circuit board, based on cluster programming and electronic messages received from the PCM. The bulb illuminates when provided a path to ground by the instrument cluster transistor.
2.2 Reasons for MIL Illumination
The MIL can turn on for several reasons:
- Bulb Test: When the ignition switch is turned to the On position, the MIL illuminates for about three seconds as a bulb test.
- MIL Lamp-On Message: When the cluster receives a MIL lamp-on message from the PCM, the indicator illuminates. It can flash or remain solid, as dictated by the PCM.
- 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.
2.3 Understanding One-Trip and Two-Trip Monitors
Emissions systems often require multiple failed diagnostic tests before the PCM illuminates the MIL. These are known as ‘two-trip monitors.’ Tests that trigger the MIL after a single failure are called ‘one-trip monitors.’ A trip is defined as starting the vehicle and operating it to meet the criteria to run a given monitor.
3. Dealing with MIL Illumination: What to Do?
If the MIL illuminates, it’s essential to understand the potential issues and how to address them.
3.1 Immediate Steps to Take
Certain conditions, like a loose gas cap or poor fuel quality, may illuminate the light after starting the engine. If the light persists through several driving cycles, the vehicle should be serviced. In most cases, the vehicle will drive normally without requiring a tow.
3.2 Risks of Prolonged Driving with the MIL On
Driving for an extended period with the MIL on can cause further damage to the emission control system and affect fuel economy and driveability. The vehicle must be repaired before any emissions test. If the light flashes, severe catalytic converter damage and power loss can occur, requiring immediate service.
3.3 Retrieving and Erasing Codes
Retrieving codes can be done by turning the ignition key On/Off three times in succession, leaving it in the On position the fourth time. The digital odometer will display the codes. If no codes are present, “Done” will appear. Erasing codes can be done using a DRB III tool, which also erases all OBD II information, including warm-up cycles, trips, and Freeze Frame data.
4. Common Chrysler Diagnostic Trouble Codes (DTCs)
A Diagnostic Trouble Code indicates that the PCM has recognized an abnormal condition in the system. DTCs result from system or circuit failures but do not directly identify the failed component.
4.1 Understanding the Code Structure
A typical code structure is P0100, where:
- P = Powertrain
- 0 = Standard
- 1 = Emission Management
- 00 = Specific fault
4.2 Key to Understanding DTCs
- (M) Check Engine Lamp (MIL) will illuminate during engine operation if this Diagnostic Trouble Code was recorded.
- (G) Generator Lamp Illuminated – Chrysler uses ISO 9142-2 OBDII Communications Protocol

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. |
