Pinpoint Test O: The RKE (Remote Keyless Entry) Transmitter Is Inoperative

  1. O1 CHECK FOR THE CORRECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTERS 
    • Check that the correct RKE  transmitters are used with the vehicle.

    Are the correct RKE transmitters present? 

    • Yes  : GO to O2 
    • No  : The system cannot be tested without the correct RKE  transmitters. INFORM the customer the correct RKE  transmitters must be present to proceed with diagnosis of the system.
  2. O2 CHECK THE RECORDED BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE SELF-TEST 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the BCM  self-test.

    Is Diagnostic Trouble Code (DTC) B1D21:62 present? 

    • Yes  : GO to O3 
    • No  : GO to  O4
  3. O3 RESYNCHRONIZE THE INOPERATIVE RKE (REMOTE KEYLESS ENTRY) TRANSMITTERS 
    • Place the inoperative Integrated Keyhead Transmitter (IKT) in the ignition lock cylinder.
    • Ignition OFF.
    • Ignition ON.
    • Ignition OFF.
    • Press any button on the RKE  transmitter.

    Does the RKE transmitter operate? 

    • Yes  : The system is OK.
    • No  : GO to O4 
  4. O4 CHECK THE FUNCTIONALITY OF THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER 
    • Press each button on the RKE  transmitter.

    Does any button operate correctly? 

  5. O5 CHECK IF THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER IS PROGRAMMED 
    • Attempt to start the engine using the suspect Integrated Keyhead Transmitter (IKT).

    Does the engine start? 

  6. O6 CHECK THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER BATTERY 
    • Open the suspect Integrated Keyhead Transmitter (IKT). Refer to the Owner's Literature for Integrated Keyhead Transmitter (IKT) battery replacement procedure.
    • Verify the correct battery is used (CR2032).
    • Remove the battery and measure the voltage.

    Is the voltage greater than 2.5 volts? 

    • Yes  : GO to O7 
    • No  : INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the Integrated Keyhead Transmitter (IKT) (weak or dead batteries do not erase Transmitter Identification Codes (TICs) from memory).
  7. O7 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE (REMOTE KEYLESS ENTRY) TRANSMITTER 
    • Press a button on the customer's second RKE  transmitter, or a known good RKE  transmitter that is correct for the vehicle.

    Does the known good RKE transmitter operate? 

  8. O8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION 
    • Disconnect and inspect all of the BCM  connectors.
    • Repair:
      • corrosion (install new connectors or terminals-clean module pins)
      • damaged or bent pins-install new terminals pins
      • pushed-out pins-install new pins as necessary
    • Reconnect all the BCM  connectors and make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    • Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM  .

      REFER to: BODY CONTROL MODULE (BCM) .

    • No  : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
