Pinpoint Test R : The RKE (Remote Keyless Entry) Transmitter Is Inoperative (With Push Button Start)

NOTE: All the customer passive keys need to be present when diagnosing the RKE system

  1. R1 CHECK FOR THE CORRECT PASSIVE KEY

    • Check that the correct passive keys are used with the vehicle.

    Are all the correct passive keys present? 

    Yes  GO to  R2
    No  The system cannot be tested without the correct passive keys. INFORM the customer the correct passive keys must be present to proceed with diagnosis of the system.

  2. R2 CHECK THE BUTTONS ON THE SUSPECT PASSIVE KEY

    • Press the buttons on the passive key (twice for the liftgate/luggage compartment lid release).

    Do any of the functions operate? 

    Yes  GO to Pinpoint Test S 
    No  GO to  R3

  3. R3 CHECK FOR COMMUNICATION WITH THE BCM (BODY CONTROL MODULE) AND RFA (REMOTE FUNCTION ACTUATOR) MODULE

    • Ignition ON.
    • Using a diagnostic scan tool, carry out a network test.

    Does the BCM and the RFA module pass the network test? 

    Yes  GO to  R4
    No  REFER to: Communications Network

  4. R4 CHECK FOR RFA (REMOTE FUNCTION ACTUATOR) MODULE DTC (DIAGNOSTIC TROUBLE CODE) U201F:00, U201F:13 OR U201F:29

    No  GO to  R5

  5. R5 RESYNCHRONIZE THE INOPERATIVE PASSIVE KEY

    • Ignition OFF.
    • Ignition ON.
    • Ignition OFF.
    • Within 30 seconds, press any button on the suspect passive key 3 times consecutively.
    • Check the operation of the suspect passive key.

    Does the suspect passive key operate correctly? 

    Yes  The system is OK. The concern was caused by a passive key out of synchronization.
    No  If an individual passive key is inoperative, GO to  R6If both passive keys are inoperative, GO to  R7

  6. R6 RESYNCHRONIZE THE INOPERATIVE PASSIVE KEY USING THE SECOND PASSIVE KEY

    • Press any button on the operational passive key.
    • Within 30 seconds, press any button on the suspect passive key.
