Pinpoint Test H: The RKE Transmitter Is Inoperative

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
  1. H1 CHECK FOR THE CORRECT IKTs 
    • NOTE: Make sure the IKTs are those provided with the OEM system and not from an aftermarket system, or a dealer-installed system that may have been installed on the vehicle.

      Check that the correct IKTs are used with the vehicle. Compare the IKTs with the one shown in Handles, Locks, Latches and Entry Systems in the Description and Operation .

    • Are the correct RKE transmitters present? 
    • Yes  : GO to H2.
    • 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. H2 CHECK THE RKE OPERATION WHEN THE TPM MODULE 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 H3.
    • No  : GO to  H4.
  3. H3 CHECK THE RKE OPERATION WHEN THE TPM MODULE 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  H11.
  4. H4 PERFORM THE NETWORK TEST ON THE TPM MODULE 
    • Connect the scan tool.
    • Ignition ON.
    • Perform the network test on the TPM module.
    • Does the TPM module pass the network test? 
  5. H5 CHECK FOR TPMS DTCs 
    • Perform the BCM self-test.
    • Are any TPMS DTCs recorded? 
    • Yes  : DIAGNOSE all TPMS DTCs first. REFER to WHEELS AND TIRES .
    • No  : GO to H6.
  6. H6 CHECK THE RECORDED BCM DTCs FROM THE SELF-TEST 
    • Check the recorded results from the BCM self-test.
    • Are any DTCs recorded? 
    • Yes  : For DTC B10AB: 00 GO to H7.

      For DTC B1218:00 GO to  H8.

      For all other DTCs, REFER to DTC CHARTS .

    • No  : GO to  H8.
  7. H7 RESYNCHRONIZE THE INOPERATIVE IKT 
    • Ignition OFF.
    • Ignition ON.
    • Ignition OFF.
    • Press any button on the IKT.
    • Does the RKE feature operate? 
    • Yes  : The system is OK. CLEAR the DTCs. REPEAT the self-test.
    • No  : GO to H8.
  8. H8 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED 
    • Enter the following diagnostic mode on the scan tool: BCM DataLogger.
    • Press a button on the IKT while observing the BCM PIDs (TIC_LAST_BC and LST_RKE_xMTR).
    • Does the Transmitter Identification Code (TIC) and RKE command show up on the scan tool screen when a button is pressed? 
    • Yes  : GO to H9.
    • No  : GO to  H10.
  9. H9 CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED 
    • Enter the following diagnostic mode on the scan tool: BCM DataLogger.
    • Press a button on the IKT and compare the BCM PID (TIC_LAST_BC) with the PIDs (TIC_01_BCM, 2, 3, 4, 7, 8, 9, or 10).
    • Does the TIC displayed match any of the TICs stored in memory? 
    • Yes  : GO to  H12.
    • No  : PROGRAM the inoperative IKT individually or PROGRAM all the IKTs. REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) for the programming procedures. If all the IKTs are to be programmed, INFORM the customer that any IKTs not present need to be programmed. CLEAR the DTCs. REPEAT the self-test.
  10. H10 CHECK THE IKT BATTERY 
    • Using a thin coin, open the IKT.
    • 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 IKT battery and measure the voltage.
    • Is the voltage greater than 2.5 volts? 
    • Yes  : GO to H11.
    • 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). TEST the system for normal operation.
  11. H11 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD IKT 
    • Enter the following diagnostic mode on the scan tool: BCM DataLogger.
    • Use the customer's second IKT, or a known good RKE transmitter that is correct for the vehicle, press a button on the IKT while observing the BCM PID (TIC_LAST_BC).
    • Does the TIC show up on the scan tool when a button is pressed? 
    • Yes  : REPLACE the inoperative IKT and PROGRAM the new IKT individually or PROGRAM all the IKTs. REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) for the programming procedures. If all the IKTs are to be programmed, INFORM the customer that any IKTs not present need to be programmed. CLEAR the DTCs. REPEAT the self-test.
    • No  : GO to H12.
  12. H12 CHECK FOR CORRECT BCM OPERATION 
    • Disconnect all the BCM connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the BCM connectors and make sure they seat correctly.
