  1. Verify the customer concern.
  2. Visually inspect for obvious signs of electrical damage.
    VISUAL INSPECTION CHART

    Electrical
    • Smart junction box (SJB) fuse 35 (10A)
    • Parking aid sensors
    • Parking aid disable switch
    • Parking aid speaker (part of the parking aid module [PAM])
    • Reversing lamps
    • Wiring, terminals or connectors
  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.
  4. 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.
  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.
    • Refer to MODULE COMMUNICATIONS NETWORK article, No Power To The Scan Tool, to diagnose no communication with the scan tool.
  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 the continuous memory DTCs.
  8. Clear the continuous DTCs and carry out the self-test diagnostics for the PAM.
    9. NOTE: Follow the non-network DTC diagnostics (BXXXX, CXXXX, PXXXX) prior to the network DTC diagnostics (UXXXX).
