Pinpoint Test L: The RKE Transmitter Is Inoperative

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 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 
    • Check that the correct IKTs are used with the vehicle. Compare the IKTs with the one shown in DESCRIPTION AND OPERATION .
      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.
    • Are all the correct IKTs present? 
  1. 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? 
  1. 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? 
  1. 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? 
  1. 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? 
  1. 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? 
  1. 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? 
  1. 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.
