Inspection and Verification

Inspection and Verification

1. Verify the customer concern by checking the air bag indicator in the instrument cluster. Refer to Prove Out the System in this section.
2. Visually inspect for obvious signs of mechanical or electrical damage using the following chart,

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.

NOTE: Make sure to use the latest scan tool software release.

4. 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.

5. 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.
- See COMMUNICATIONS NETWORK. No power to the scan tool or to the diagnose no communication with the scan tool. Initial Inspection and Diagnostic Overview

6. If the scan tool does not communicate with the vehicle: See COMMUNICATIONS NETWORK. No response from the powertrain control module (PCM). Initial Inspection and Diagnostic Overview
7. Carry out the network test
- If the scan tool responds with no communication for one or more modules, see COMMUNICATIONS NETWORK. Initial Inspection and Diagnostic Overview
- If the network test passes, retrieve and record continuous memory diagnostic trouble codes (DTCs).

8. Clear the continuous DTCs and carry out the self-test diagnostics for the RCM and OCS module.
9. If the DTCs retrieved are related to the concern, see DIAGNOSTIC TROUBLE CODE (DTC) INDEX - RESTRAINTS CONTROL MODULE (RCM). Restraints Control Module (RCM)
10. If no DTCs related to the concern are retrieve, see SYMPTOM TROUBLESHOOTING CHART - AIR BAG SYSTEM. Symptom Related Diagnostic Procedures
