  1. I1 RETRIEVE THE RECORDED DTC FROM BOTH THE CONTINUOUS AND ON-DEMAND PARKING AID MODULE SELF-TESTS 
    • Retrieve the recorded parking aid module DTCs from the continuous and on-demand self-tests.
    • Are any DTCs recorded? 
  2. I2 CHECK CIRCUIT 1435 (DG/VT) FOR A SHORT TO VOLTAGE 
    • Key in OFF position.
    • Disconnect: Parking Aid Module C3267.
    • Measure the voltage between the parking aid module C3267-11, circuit 1435 (DG/VT), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : INSTALL a new parking aid switch. REFER to PARKING AID SWITCH . CLEAR the DTCs. REPEAT the self-test.
    • No  : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
  6. I6 CHECK FOR CORRECT PARKING AID MODULE OPERATION 
    • Disconnect the parking aid module connector.
    • Check for:
      • corrosion
      • pushed-out pins
    • Connect the parking aid module connector and make sure it seats correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
    • Yes  : INSTALL a new parking aid module. REFER to PARKING AID MODULE . CLEAR the DTCs. REPEAT the self-test. CARRY OUT the diagnostic tool data link test.
    • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
