Pinpoint Test L: The RKE Transmitter Is Inoperative

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: All IKT transmitters must be present to begin diagnosis of the RKE system.
NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
  1. L1 CHECK FOR THE CORRECT RKE TRANSMITTERS 
      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 the DESCRIPTION AND OPERATION  portion of this service information.
    • Are all the correct IKTs present? 
    • Yes  : GO to L2.
    • No  : The system cannot be tested without the correct IKTs. INFORM the customer that all the correct IKTs must be present to proceed with diagnosis of the system.
  2. L2 CHECK THE RECORDED SJB AND IPC DTCs FROM THE SELF-TEST 
    • Check the recorded results from the SJB and IPC self-test.
    • Is DTC B2425 or DTC B109E:86 recorded? 
    • Yes  : For DTC B2425, GO to L3.

      For DTC B109E:86, GO to PINPOINT TEST R .

    • No  : GO to  L4.
  3. L3 RESYNCHRONIZE THE INOPERATIVE IKT 
    • Ignition OFF.
    • Ignition ON.
    • Leave the IKT key in the ON position for a minimum of 6 seconds.
    • Ignition OFF.
    • Press any button on the IKT.
    • Does the IKT operate? 
    • Yes  : The system is OK. CLEAR the DTCs. REPEAT the self-test.
    • No  : GO to L4.
  4. L4 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED 
    • Enter the following diagnostic mode on the scan tool: SJB DataLogger.
    • Press lock and unlock on the IKT while observing the SJB PIDs (TIC_LAST) and (TNSMT_CMD).
    • Does the TIC and RKE command show up on the scan tool screen when a button is pressed? 
    • Yes  : GO to L5.
    • No  : GO to  L6.
  5. L5 CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED 
    • Enter the following diagnostic mode on the scan tool: SJB DataLogger.
    • Press a button on the IKT and compare the SJB PID (TIC_LAST) with the PIDs (TIC_1, 2, 3, 4, 7, 8, 9, or 10).
    • Does the TIC displayed match any of the TICs stored in memory? 
    • Yes  : GO to  L8.
    • No  : PROGRAM the inoperative IKT individually or PROGRAM all the IKTs. REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) -- FUSION, MILAN & MKZ article for the programming procedures. If all the IKTs are to be programmed, INFORM the customer that any IKTs not present need to be programmed. TEST the system for normal operation.
  6. L6 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 L7.
    • 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.
  7. L7 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD IKT 
    • Enter the following diagnostic mode on the scan tool: SJB 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 SJB PID (TIC_LAST).
    • Does the TIC show up 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 ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) -- FUSION, MILAN & MKZ article for the programming procedures. If all the IKTs are to be programmed, INFORM the customer that any IKTs not present need to be programmed. TEST the system for normal operation.
    • No  : GO to L8.
  8. L8 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the SJB connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present?
