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

• Press each button on the RKE  transmitter (twice for the liftgate release).

Do any of the RKE functions operate? 

• Yes  : GO to PINPOINT TEST S 
• No  : GO to Q2 

• 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.

• 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

• 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

• 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 RKE transmitter now function? 

• Yes  : The system is OK. The concern was cause by an RKE  transmitter out of synchronization.
• No  : GO to Q6 

• Open the suspect 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 Codes (TICs) from memory).

• NOTE: Any RKE  transmitter not present is erased from the BCM  memory during the RKE  transmitter programming procedure.

  Program the inoperative RKE  transmitter.

  Refer to: REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING  .

• Press the lock and then the unlock buttons on the suspect RKE  transmitter.

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 

• NOTE: Any RKE  transmitter not present is erased from the BCM  memory during the RKE  transmitter programming procedure.

  Program a known good RKE  transmitter.

  Refer to: REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING  .

• Press the lock and then the unlock buttons on the known good RKE  transmitter.

Do the doors lock and then unlock? 

• Yes  : REPLACE the suspect RKE  transmitter.

  If the suspect RKE  transmitter is an Integrated Keyhead Transmitter (IKT), ERASE and PROGRAM the keys.

  Refer to: ERASE ALL KEYS AND KEY PROGRAMMING .

  If the suspect RKE  transmitter is a key fob, PROGRAM the RKE  transmitter.

  Refer to: REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING  .

• No  : GO to Q9 

• Disconnect and inspect all 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.
