Inspection and Verification: Notes

Visually inspect for obvious signs of mechanical or electrical damage.

VISUAL INSPECTION CHART

Mechanical	Electrical
Accessory drive belt Brake fluid level Door adjustment Engine coolant level Engine oil level Fuel tank Fuel evaporative system Washer fluid level Tire pressure	Body Control Module (BCM) fuse(s). 11 (10A) (IPC ) 32 (15A) (compass) Wiring, terminals or connectors Compass module (without SYNC®) Message center switch (part of the LH steering wheel switch) Instrument Panel Cluster (IPC)

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

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).

NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM .

If the scan tool does not communicate with the VCM :
- check the VCM connection to the vehicle.
- check the scan tool connection to the VCM .
- refer to MODULE COMMUNICATIONS NETWORK , No Power To The Scan Tool, to diagnose no power to the scan tool.
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 SWITCHES to diagnose no power in RUN.
- verify the scan tool operation with a known good vehicle.
- refer to MODULE COMMUNICATIONS NETWORK to diagnose no response from the PCM.
Carry out the network test.
- if the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK .
- if the network test passes, retrieve and record the continuous memory DTCs for the IPC , the Restraints Control Module (RCM), the BCM , the ABS module and the PCM.
Clear the continuous DTCs and carry out the self-test diagnostics for the IPC , BCM , PCM, ABS module and the RCM .
If the DTCs retrieved are related to the concern, go to DTC CHARTS . For all other module DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES .
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 .
