    VISUAL INSPECTION CHART

    Mechanical Electrical
    • Cruise-Control Module (C-CM) fascia cover
    • Battery Junction Box (BJB) fuse(s):
      • 13 (15A) (with adaptive cruise control)
      • 46 (15A)
    • Brake lamp relay (with adaptive cruise control, located in the BJB)
    • C-CM (with adaptive cruise control)
    • Wiring, terminals or connectors
    • Cruise control deactivator switch
    • Cruise control switch
    • PCM
    • ABS module (with adaptive cruise control)
  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. Inspect for a damaged sensor bracket, sensor fascia cover and cover foam or front bumper cover. If evidence of damage, carry out the CRUISE CONTROL MODULE (C-CM) (WITH SENSOR) ADJUSTMENT  vertical alignment . If the C-CM bracket is damaged, refer to CRUISE-CONTROL MODULE (C-CM)  to replace the bracket.
    5. NOTE: Make sure to use the latest scan tool software release.
  5. If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
    6. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
  6. 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.
  7. If the scan tool does not communicate with the vehicle:
    • Verify the ignition is in the ON position.
    • Verify the scan tool operation with a known good vehicle.
    • Refer to MODULE COMMUNICATIONS NETWORK to diagnose no response from the C-CM or the PCM.
  8. 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.
  9. Clear the continuous DTCs and carry out the self-test diagnostics for the C-CM, PCM, and the ABS module.
  10. If the DTCs retrieved are related to the concern, go to DTC CHARTS . For all other DTCs, refer to DIAGNOSTIC TROUBLE CODE (DTC) CHART the Diagnostic Trouble Code (DTC) Chart .
  11. If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
