Pinpoint Test F: The Doors Do Not Lock/Unlock Using The Remote Keyless Entry (RKE) Transmitter

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation 

Remote locking and unlocking of the doors is accomplished by the driver door module (DDM) receiving a command message from the remote keyless entry (RKE) transmitter. The DDM processes the command and sends a signal directly to the door lock actuators.

DTC B2276 (Less than 2 transmitters programmed) - is a continuous DTC that sets when the DDM detects that there are no or only one key fob programmed to the DDM.

This pinpoint test is intended to diagnose the following:

PINPOINT TEST F: THE DOORS DO NOT LOCK/UNLOCK USING THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER 

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 concern.
  1. F1 CHECK FOR THE CORRECT RKE TRANSMITTERS 
    NOTE: Make sure the RKE transmitters are the ones provided with the original equipment manufacturer system and not from an aftermarket system, 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  F2.
    2. NO  : The system cannot be tested without the correct RKE transmitters. INFORM the customer that all the correct RKE transmitters must be present to proceed with diagnosis of the system.
  2. F2 CHECK THE OPERATION OF THE RKE TRANSMITTER WITH THE KEY IN THE OFF POSITION 
    • Key in OFF position.
    • Check the operation of the RKE transmitter.
    • Does the system operate correctly now? 
    1. YES  : The system is operating as designed. INFORM the customer of the correct vehicle operation.
    2. NO  : Go to  F3.
  3. F3 CHECK THE POWER DOOR LOCK SYSTEM FOR CORRECT OPERATION 
    • Verify the door lock/unlock operation by actuating the driver door lock control switch.
    • Do all the doors lock and unlock correctly? 
    1. YES  : Go to  F4.
    2. NO  : Go to Pinpoint Test C .
  4. F4 CHECK FOR THE COMPLETE FUNCTIONALITY OF THE RKE TRANSMITTER(S) 
    • Check all the RKE transmitter buttons for correct operation.
    • Does any button operate correctly? 
    1. YES  : REPLACE the inoperative RKE transmitter. PROGRAM all RKE transmitters. REFER to Remote Keyless Entry Transmitter Programming . INFORM the customer that any RKE transmitters not present need to be programmed. CLEAR the DTCs. TEST the system for normal operation.
    2. NO  : Go to  F5.
  5. F5 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED 
    • Connect the diagnostic tool.
    • Enter the following diagnostic mode on the diagnostic tool: DDM DataLogger
    • Monitor the DDM TNSMTR_ID PID.
      • NOTE: The vehicle must be electronically unlocked prior to using any scan tools (through the RKE transmitter or door lock control switch).
    • Verify the RKE transmitter identification code (TIC) 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  F6.
    2. NO  : Go to  F7.
  6. F6 CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED 
    • Enter the following diagnostic mode on the diagnostic tool: DDM DataLogger
    • Monitor the DDM TNSMTR_ID PID.
    • Verify the RKE transmitters are programmed to the vehicle.
    • Does the TIC displayed under current RKE transmitter match any of the TICs stored in memory? 
    1. YES  : Go to  F8.
    2. NO  : PROGRAM all of the RKE transmitters. REFER to Remote Keyless Entry Transmitter Programming . INFORM the customer that any RKE transmitters not present need to be programmed. CLEAR the DTCs. TEST the system for normal operation.
  7. F7 CHECK THE RKE TRANSMITTER BATTERY 
    • Using a thin coin, open the RKE transmitter.
    • 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 RKE transmitter battery and measure the voltage.
    • Is the voltage greater than 2.5 volts? 
    1. YES  : Go to  F9.
    2. NO  : INSTALL a new battery (be sure the battery is seated correctly). DO NOT program the RKE transmitters (weak or dead batteries do not erase TICs from memory). CLEAR the DTCs. TEST the system for normal operation.
  8. F8 CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE DDM 
    • The vehicle must be electronically unlocked prior to using any scan tools (through the RKE transmitter or the door lock control switch).
    • Enter the following diagnostic mode on the diagnostic tool: Retrieve the Continuous DTCs
    • Is continuous DTC B2425 stored in the DDM? 
    1. YES  : Go to Pinpoint Test M .
    2. NO  : Go to  F9.
  9. F9 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE TRANSMITTER 
    • Enter the following diagnostic mode on the diagnostic tool: DDM Function Tests, Transmitter Test or Program Transmitter
    • 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, verify the RKE transmitter signal is being received by the DDM.
    • 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 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. TEST the system for normal operation.
    2. NO  : Go to Pinpoint Test N .
