Inspection and Verification

1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart






3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

4. NOTE: Make sure to use the latest scan tool software release.
If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).


5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC (Data Link Connector) are provided to the VCM (Vehicle Communication Module).
If the scan tool does not communicate with the VCM (Vehicle Communication Module) :

- check the VCM (Vehicle Communication Module) connection to the vehicle.

- check the scan tool connection to the VCM (Vehicle Communication Module).

- refer to No Power To The Scan Tool, to diagnose no power to the scan tool.


6. If the scan tool does not communicate with the vehicle:
- verify the ignition is in the ON mode.
- the air bag indicator (other indicators may not prove ignition on) confirms ignition ON. If the ignition does not turn on, refer to Steering Column to diagnose no power in RUN.

- verify the scan tool operation with a known good vehicle.

- refer to Information Bus to diagnose no response from the PCM.


7. Carry out the network test.
- if the scan tool responds with no communication for one or more modules, refer to Information Bus.

- if the network test passes, retrieve and record the continuous memory DTCs for the IPC (Instrument Panel Cluster), the Restraints Control Module (RCM), the BCM (Body Control Module), the ABS module and the PCM.


8. Clear the continuous DTCs and carry out the self-test diagnostics for the IPC (Instrument Panel Cluster), BCM (Body Control Module), PCM, ABS module and the RCM (Restraints Control Module).

9. If the DTCs retrieved are related to the concern, go to DTC Charts Instrumentation, Message Center and Warning Chimes. For all other module DTCs, refer to Body Control Systems.

10. If no DTCs related to the concern are retrieved, GO to Symptom Chart- Instrument Panel Cluster (IPC), GO to Symptom Chart- Information And Message Center, or GO to Symptom Chart- Warning Chimes Instrumentation, Message Center and Warning Chimes.

Instrument Panel Cluster (IPC) Dealer Test Mode

To enter the IPC (Instrument Panel Cluster) self-diagnostic mode, begin with the ignition key in the OFF mode. Press and hold the RH steering wheel switch OK button (optional IPC (Instrument Panel Cluster)) or the LH steering wheel switch OK (base IPC (Instrument Panel Cluster)). Place the ignition in the ON mode and hold the button until the display indicates ENGINEERING TEST MODE, usually within 3 to 5 seconds. Press the up or down arrow buttons to navigate through each of the display windows. To exit the IPC (Instrument Panel Cluster) self-test mode, press and hold the OK button for 3-5 seconds or place the ignition OFF.

The dealer test mode displays multiple items in a viewing window on the RH side of the IPC (Instrument Panel Cluster). Each button press advances the viewing window to the next set of items.

NOTE: Some of the displays listed in the table below use xxx's to represent a numeric or alpha-numeric value. The value may display the same amount of characters represented by the xxx's or there may be more/less depending on the type of display. For example: DTC HIST CURR xxxxxx x x may display DTC HIST CURR C10000 X. Note that there were 8 x's in the display description but only 7 digits in the actual display.

NOTE: The table below lists the displays as they appear when navigating using the down arrow button.
