  1. Refer to REMOTE KEYLESS ENTRY AND ALARM for schematic and connector information.

    Normal Operation and Fault Conditions 

    REFER to: Handles, Locks, Latches and Entry Systems - System Operation and Component Description .

    Possible Sources 

    • Wiring, terminals or connectors
    • BCM

  2. I1 CHECK FOR BCM (BODY CONTROL MODULE), DDM (DRIVER DOOR MODULE) AND PDM (PASSENGER DOOR MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the BCM self-test.

    • Using a diagnostic scan tool, carry out the DDM self-test.

    • Using a diagnostic scan tool, carry out the PDM self-test.

    Are any Diagnostic Trouble Codes (DTCs) present? 

    Yes  REFER to the DTC Chart(s) .
    No  GO to  I2

  3. I2 VERIFY THE OPERATION OF BOTH DOOR LOCK CONTROL SWITCHES

    • Press the lock and unlock buttons on both door lock control switches while observing the door lock operation.

    Does any door lock operate? 

    Yes  GO to  I3
    No  GO to  I4

  4. I3 CHECK IF THE LOCKS OPERATE IN ONLY ONE DIRECTION
