  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  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 VCM  .
  6. If the scan tool does not communicate with the vehicle:
    • verify the ignition is in RUN (ON).
      • The air bag warning indicator prove-out (other indicators may NOT prove ignition is in RUN) confirms ignition in RUN. If ignition does not enter RUN, GO to SYMPTOM CHART .
    • refer to MODULE COMMUNICATIONS NETWORK , Inspection and Verification to establish a scan tool session.
    • verify the scan tool operation with a known good vehicle.
  7. 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 Continuous Memory Diagnostic Trouble Codes (CMDTCs)
  8. Carry out the self-test diagnostics for the BCM  .
  9. Carry out the self-test diagnostics for the Steering Column Control Module (SCCM).
  10. If equipped with a start/stop switch, turn the ignition OFF. The ignition must be OFF to carry out a RFA  module self-test.
  11. If equipped with a start/stop switch, carry out the self-test diagnostics for the RFA  module.
  12. If the DTCs retrieved are related to the concern, refer to the BCM MODULE DTC CHART , the REMOTE FUNCTION ACTUATOR (RFA) MODULE DTC CHART  and/or the STEERING COLUMN CONTROL MODULE (SCCM) DTC CHART . If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
