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

  1. Normal Operation and Fault Conditions 

    REFER to: Handles, Locks, Latches and Entry Systems - Vehicles With: One-Touch Open Driver Window - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B10AB:00 Remote Keyless Entry Synchronization: No Sub Type Information Sets when the BCM detects the rolling counter received from a RKE transmitter is out of synchronization with the rolling counter stored in the module.
    BCM B1218:00 Transmitter Identification Code: No Sub Type Information Sets when the BCM detects and invalid Transmitter Identification Code (TIC).

    Possible Sources 

    • Key batteries
    • Key
    • Key button pressed a substantial amount of times while outside the range of the vehicle
    • Key programming
    • Network concern

    Visual Inspection and Pre-checks 

    • Inspect the RKE transmitter for damage.
    • Check for aftermarket RKE transmitters.

  2. O1 CHECK ALL THE BUTTONS ON THE SUSPECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTER

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

    Do any of the RKE functions operate? 

    Yes  GO to Pinpoint Test P 
    No  GO to  O2

  3. O2 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  O3
    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.

  4. O3 RESYNCHRONIZE THE INOPERATIVE 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 an RKE transmitter out of synchronization.
    No  GO to  O4

  5. O4 RESYNCHRONIZE THE INOPERATIVE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER USING A SECOND 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 RKE transmitter now function? 

    Yes  The system is OK. The concern was cause by an RKE transmitter out of synchronization.
    No  GO to  O5

  6. O5 CHECK THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER BATTERY

    • Open the suspect RKE transmitter. Refer to the Owner's Literature for the Intergrated Keyhead Transmitter (IKT) battery replacement procedure.

    • NOTE: 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  O6
    No  INSTALL a new battery (make sure the battery seats correctly). DO NOT reprogram the RKE transmitter (weak or dead batteries do not erase Transmitter Identification Codes (TICs) from memory).

  7. O6 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.

    • 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  O7

  8. O7 PROGRAM A KNOWN GOOD RKE (REMOTE KEYLESS ENTRY) TRANSMITTER (KEY FOB)

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

    • 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. If the suspect RKE transmitter is a key fob, PROGRAM the RKE transmitter. REFER to: Remote Keyless Entry (RKE) Transmitter Programming .
    No  GO to  O8

  9. 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles 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.
