Pinpoint Test R : The RKE Transmitter Is Inoperative

WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

  1. R1 CHECK FOR THE CORRECT IKTs

    • Check that the correct IKTs are used with the vehicle.

    Are the correct IKTs present? 

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

  2. R2 CHECK THE RKE OPERATION WHEN THE RADIO TRANSCEIVER MODULE (RTM) IS IN AN AWAKE MODE

    • Open and close the driver door.
    • Press any button on the IKT.

    Does the RKE feature operate? 

    Yes  GO to  R3.
    No  GO to  R4.

  3. R3 CHECK THE RKE OPERATION WHEN THE RADIO TRANSCEIVER MODULE (RTM) IS IN A SLEEP MODE

    • Ignition OFF.
    • Let the vehicle sit for 10 minutes to allow the vehicle modules to go into a sleep mode.
    • Press any button on the IKT.

    Does the RKE feature operate? 

    Yes  The system is operating correctly at this time.
    No  GO to  R12.

  4. R4 CHECK FOR COMMUNICATION WITH THE RADIO TRANSCEIVER MODULE (RTM)

    • Ignition ON.
    • Using a diagnostic scan tool, perform the network test.

    Does the Radio Transceiver Module (RTM) pass the network test? 

    Yes  GO to  R5.
    No  DIAGNOSE the Radio Transceiver Module (RTM) not responding to the scan tool. REFER to Module Communications Network .

  5. R5 CHECK FOR TPMS -RELATED DTCs

    • Using a diagnostic scan tool, perform the BCM self-test.

    Are any TPMS related DTCs present? 

    Yes  DIAGNOSE all TPMS -related DTCs first. REFER to Wheels and Tires .
    No  GO to  R6.

  6. R6 CHECK FOR DTC B10AB:00 OR B1218:00

    • Using a diagnostic scan tool, carry out the BCM self-test.

    Is DTC B10AB:00 or B1218:00 present? 

    Yes  For DTC B10AB:00 GO to  R7.For DTC B1218:00 GO to  R8.
    No  GO to  R8.

  7. R7 RESYNCHRONIZE THE INOPERATIVE IKT

    • Ignition OFF.
    • Ignition ON.
    • Ignition OFF.
    • Press any button on the IKT 4 times consecutively within 30 seconds.

    Does the IKT operate correctly? 

    Yes  The system is OK. The concern was cause by an IKT out of synchronization.
    No  GO to  R8.

  8. R8 CHECK THE RKE TRANSMITTER PIDs

    • Ignition ON.
    • Using a diagnostic scan tool, view the BCM PIDs.
    • Using a diagnostic scan tool, monitor the following BCM PIDs :
      • Last Received (RKE) Transmitter Button Press (LST_RKE_xMTR)
      • Last Received (TIC) Code Value (TIC_LAST_BC)
    • Press a button on the IKT while observing the BCM PIDs.

    Does the TIC and RKE command display on the scan tool when a button is pressed? 

    Yes  GO to  R9.
    No  GO to  R10.

  9. R9 CHECK IF THE IKTs ARE PROGRAMMED USING THE TRANSMITTER ID CODE (TIC) PIDs

    • Using a diagnostic scan tool, monitor the following BCM PIDs :
      • Last Received (TIC) Code Value (TIC_LAST_BC)
      • Programmed Transmitter ID Code (TIC) Value 1 (TIC_01_BCM)
      • Programmed Transmitter ID Code (TIC) Value 2 (TIC_02_BCM)
      • Programmed Transmitter ID Code (TIC) Value 3 (TIC_03_BCM)
      • Programmed Transmitter ID Code (TIC) Value 4 (TIC_04_BCM)
      • Programmed Transmitter ID Code (TIC) Value 7 (TIC_07_BCM)
      • Programmed Transmitter ID Code (TIC) Value 8 (TIC_08_BCM)
      • Programmed Transmitter ID Code (TIC) Value 9 (TIC_09_BCM)
      • Programmed Transmitter ID Code (TIC) Value 10 (TIC_10_BCM)
    • Press a button on each IKT and compare the BCM TIC_LAST_BC PID with the other PIDs.

    Does the last TIC displayed match any of the TICs stored in memory? 

    Yes  GO to  R13.
    No  REPLACE the suspect IKT. REFER to Key Programming Using Diagnostic Equipment in Anti-Theft Passive Anti-Theft System (PATS) .

  10. R10 CHECK THE IKT BATTERY

    • Remove the IKT battery. Refer to the Owner Guide for battery removal instructions.
    • 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).
    • Measure the IKT battery voltage.

    Is the voltage greater than 2.5 volts? 

    Yes  GO to  R11.
    No  INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the IKT (weak or dead batteries do not erase TICs from memory).

  11. R11 CHECK FOR A SIGNAL WITH A KNOWN GOOD IKT USING THE LAST RECEIVED (TIC) CODE VALUE (TIC_LAST_BC) PID

    • Using a diagnostic scan tool, view the BCM PIDs.
    • Use the customer's second IKT, or a known good IKT that is correct for the vehicle, press a button on the IKT while observing the BCM TIC_LAST_BC PID.

    Does the TIC display on the scan tool when a button is pressed? 

    Yes  REPLACE the inoperative IKT and PROGRAM the inoperative IKT individually or PROGRAM all the IKTs. REFER to Key Programming Using Diagnostic Equipment in Anti-Theft Passive Anti-Theft System (PATS) .
    No  GO to  R13.

  12. R12 CHECK FOR CORRECT RADIO TRANSCEIVER MODULE (RTM) OPERATION

    NOTE: The Radio Transceiver Module (RTM) is also known as the TPM module.

    • Disconnect and inspect the Radio Transceiver Module (RTM) connector.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the Radio Transceiver Module (RTM) connector. Make sure it seats and latches correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK On-Line Automotive Service Information System(OASIS) for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new TPM module. REFER to Tire Pressure Monitoring System (TPMS) .
    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.

  13. R13 CHECK FOR CORRECT BCM OPERATION

    • Disconnect and inspect all the BCM connectors.
    • Repair:
      • corrosion (install new connector or terminals - 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 On-Line Automotive Service Information System(OASIS) for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, Refer to BCM Hardware Testing .
    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.
