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

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: All RKE 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. H1 CHECK FOR THE CORRECT RKE TRANSMITTERS 
    NOTE: Make sure the RKE transmitters are those provided with the original equipment manufacturer (OEM) system and not from an aftermarket or a dealer-installed system that may have been installed on the vehicle.
    • Check that the correct RKE transmitters are used with the vehicle.
    • Are all the correct RKE transmitters present? 
    1. YES  : Go to  H2.
    2. NO  : The system cannot be tested without the correct RKE transmitters. INFORM the customer that all the correct RKE transmitters must to be present to proceed with diagnosis of the system.
  2. H2 CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE SJB 
    • Check the recorded results from the SJB self-test.
    • Is continuous DTC B2425 present? 
    1. YES  : Go to  H3.
    2. NO  : Go to  H7.
  3. H3 RESYNCHRONIZE THE INOPERATIVE RKE TRANSMITTER 
    • Key in OFF position.
    • Press any button on the inoperative RKE transmitter 4 times consecutively within 30 seconds.
    • Does the RKE transmitter operate correctly now? 
    1. YES  : The transmitter is now synchronized. CLEAR the DTCs. REPEAT the self-test.
    2. NO  : Go to  H4.
  4. H4 CHECK FOR A SECOND RKE TRANSMITTER 
    • Check for another RKE transmitter that operates with the vehicle.
    • Is there another RKE transmitter that operates with the vehicle? 
    1. YES  : Go to  H5.
    2. NO  : Go to  H6.
  5. H5 RESYNCHRONIZE THE INOPERATIVE RKE TRANSMITTER USING THE SECOND RKE TRANSMITTER 
    • Press any button on the operational RKE transmitter.
    • Within 30 seconds, press a button on the inoperative RKE transmitter.
    • Check the inoperative RKE transmitter for correct operation.
    • Does the inoperative RKE transmitter operate now? 
    1. YES  : The transmitter is now synchronized. CLEAR the DTCs. REPEAT the self-test.
    2. NO  : Go to  H6.
  6. H6 PROGRAM THE INOPERATIVE RKE TRANSMITTER OR ALL THE RKE TRANSMITTERS 
    • Program the inoperative RKE transmitter individually using a scan tool or program all RKE transmitters using the manual key cycle method. Refer to Remote Keyless Entry Transmitter Programming .
    • Does the inoperative RKE transmitter(s) operate now? 
    1. YES  : The transmitter(s) is now synchronized. INFORM the customer that any RKE transmitters not present need to be programmed. CLEAR the DTCs. REPEAT the self-test.
    2. NO  : Go to  H7.
  7. H7 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED 
    • Enter the following diagnostic mode on the diagnostic tool: Remote Keyless Entry
      • NOTE: The remote keyless entry test is accessed through the scan tool by selecting Tool box, Body, Security.
    • Monitor the RKE transmitter identification code (TIC) through the scan tool menus.
    • Verify the RKE transmitter signal is being received. Press a button on the RKE transmitter while observing the scan tool.
    • Does the TIC show up on the scan tool screen when a button is pressed? 
    1. YES  : Go to  H8.
    2. NO  : Go to  H9.
  8. H8 DETERMINE IF THE RKE TRANSMITTERS ARE PROGRAMMED 
    • Enter the following diagnostic mode on the diagnostic tool: Remote Keyless Entry
    • Monitor the RKE transmitter TIC/DATA through the scan tool menus.
    • Verify the RKE transmitters are programmed to the vehicle.
    • Does the TIC displayed under RKE transmitter match any of the TICs stored in memory? 
    1. YES  : Go to  H10.
    2. NO  : PROGRAM all the RKE transmitters. REFER to Remote Keyless Entry Transmitter Programming . INFORM the customer that any RKE transmitters not present need to be programmed. TEST the system for normal operation.
  9. H9 CHECK THE RKE TRANSMITTER BATTERY 
    • Using a thin coin, open the RKE transmitter.
    • Do not clean off any grease from the battery terminal on the back surface of the circuit board.
    • Verify the correct battery is being used (CR2032).
    • Remove the RKE transmitter battery and measure the voltage.
    • Is the voltage greater than 2.5 volts? 
    1. YES  : Go to  H10.
    2. NO  : INSTALL a new battery. Do not program the RKE transmitters (damaged or dead batteries do not erase TICs from memory). TEST the system for normal operation.
  10. H10 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE TRANSMITTER 
    • Enter the following diagnostic mode on the diagnostic tool: Remote Keyless Entry
    • Monitor the RKE transmitter TIC/DATA through the scan tool menus.
    • Using the customer's second RKE transmitter or a known good RKE transmitter that is correct for the vehicle (and programmed to the vehicle), verify the RKE transmitter signal is being received.
    • Does the TIC show up on the scan tool when a button is pressed on the RKE transmitter? 
    1. YES  : REPLACE the inoperative RKE transmitter. PROGRAM all the RKE transmitter(s). REFER to Remote Keyless Entry Transmitter Programming . INFORM the customer that any RKE transmitters not present need to be programmed. CLEAR the DTCs. REPEAT the self-test.
    2. NO  : Go to  H11.
  11. H11 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB connectors.
    • Check for:
