Pinpoint Test Q: The RKE (Remote Keyless Entry) Transmitter Is Inoperative (Without Push Button Start)

  1. Q1 CHECK ALL THE BUTTONS ON THE SUSPECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTER 
    • Press each button on the RKE  transmitter (twice for the liftgate).

    Do any of the functions operate? 

  2. Q2 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 Q3 
    • 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.
  3. Q3 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) B1D21:62 FROM THE BCM (BODY CONTROL MODULE) SELF-TEST 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the BCM  self-test.

    Is DTC B1D21:62 present? 

    • Yes  : If only one transmitter is present, GO to Q4 

      If more than one transmitter is present, GO to  Q5

    • No  : GO to  Q6
  4. Q4 RESYNCHRONIZE THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER 
    • Ignition OFF.
    • Within close proximity of the vehicle, press any of the buttons 3 consecutive times within 30 seconds.
    • Observe the vehicle for audible or visual feedback.

    Does the RKE transmitter now function? 

    • Yes  : The system is OK. The concern was cause by a RKE  transmitter out of synchronization.
    • No  : GO to  Q6
  5. Q5 RESYNCHRONIZE THE INOPERATIVE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER USING THE FUNCTIONING RKE (REMOTE KEYLESS ENTRY) TRANSMITTER 
    • Ignition OFF.
    • Press any button on the functioning RKE  transmitter and activate the locks or the liftgate release.
    • Within 30 seconds of activating the locks or the liftgate release, press a button on the non-functioning RKE  transmitter.
    • Observe the vehicle for audible or visual feedback.

    Does the suspect RKE transmitter now function? 

    • Yes  : The system is OK. The concern was cause by a RKE  transmitter out of synchronization.
    • No  : GO to Q6 
  6. Q6 CHECK THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER BATTERY 
    • Open the RKE  transmitter. Refer to the Owner's Literature for the Integrated Keyhead Transmitter (IKT) battery replacement procedure.
    • Do not clean off any grease from the battery terminals on the back surface of the circuit board.
    • Verify the correct battery is used (CR2032).
    • Remove the RKE  transmitter battery and measure the voltage.

    Is the voltage greater than 2.5 volts? 

    • Yes  : GO to Q7 
    • No  : INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the RKE  transmitter (weak or dead batteries do not erase transmitter identification from memory).
  7. Q7 PROGRAM THE SUSPECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTER 
    NOTE: Any RKE  transmitter not present is erased from the BCM  memory during the RKE  transmitter programming procedure.

    Do the doors lock and then unlock? 

    • Yes  : The system is OK. The concern was caused by an unprogrammed RKE  transmitter.
    • No  : GO to Q8 
  8. Q8 PROGRAM A KNOWN GOOD RKE (REMOTE KEYLESS ENTRY) TRANSMITTERS (KEY FOB) 
    NOTE: Any RKE  transmitter not present is erased from the BCM  memory during the RKE  transmitter programming procedure.

    Do the doors lock and then unlock? 

  9. Q9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION 
    • Disconnect and inspect all BCM  connectors.
    • Repair:
      • corrosion (install new connector or terminal - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the BCM  connectors. 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 TSB  . If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW the TSB  instructions. If no TSB  addresses 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 a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
