  1. Verify the customer concern by checking the air bag warning indicator in the instrument cluster (IC) module. Refer to Prove Out Procedure .
  2. Visually inspect for obvious signs of mechanical or electrical damage. Do not disconnect electrical connectors until directed to do so within the pinpoint test.

  6. If the scan tool does not communicate with the vehicle:
    • verify the ignition key is in the ON position.
    • verify the scan tool operation with a known good vehicle.
    • refer to MODULE COMMUNICATIONS NETWORK article 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 MODULE COMMUNICATIONS NETWORK article.
    • If the network test passes, retrieve and record on-demand and continuous memory DTCs from the RCM.
  8. If the DTCs retrieved are related to the concern, go to the SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DIAGNOSTIC TROUBLE CODE INDEX . For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article.
