Pinpoint Test I: The Luggage Compartment Lid Is Inoperative Using The Remote Keyless Entry (RKE) Transmitter

Normal Operation 

The driver door module (DDM) receives a signal from the RKE transmitter to open the luggage compartment. The DDM supplies voltage to the luggage compartment release solenoid through circuit 84 (VT/YE), releasing the luggage compartment lid.

This pinpoint test is intended to diagnose the following:

• RKE transmitter
• DDM

PINPOINT TEST I: THE LUGGAGE COMPARTMENT LID IS INOPERATIVE USING THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER 

1. I1 CHECK THE LUGGAGE COMPARTMENT LID RELEASE SWITCH OPERATION 
   • Press the luggage compartment lid release switch.
   • Does the luggage compartment lid open? 
   1. YES  : Go to  I2.
   2. NO  : Go to Pinpoint Test B .
2. I2 CHECK FOR COMPLETE FUNCTIONALITY OF THE RKE TRANSMITTER(S) 
   • Check all the RKE transmitter buttons for correct operation.
   • Does the panic alarm button operate correctly? 
   1. YES  : REPLACE the inoperative RKE transmitter. REPROGRAM all the RKE transmitters. REFER to Remote Keyless Entry Transmitter Programming . INFORM the customer any RKE transmitters not present need to be reprogrammed. CLEAR the DTCs. TEST the system for normal operation.
   2. NO  : Go to  I3.
3. I3 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. Using a scan tool, 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  I4.
   2. NO  : Go to  I5.
4. I4 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  I6.
   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 reprogrammed. CLEAR the DTCs. TEST the system for normal operation.
5. I5 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  I7.
   2. NO  : INSTALL a new battery (be sure the battery is seated correctly). DO NOT reprogram the RKE transmitters (weak or dead batteries do not erase TICs from memory). CLEAR the DTCs. TEST the system for normal operation.
6. I6 CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE DDM 
   NOTE: 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 DTCs
   • Is continuous DTC B2425 stored in the DDM? 
   1. YES  : Go to Pinpoint Test M .
   2. NO  : Go to  I7.
7. I7 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE TRANSMITTER 
   • Use the customer's second RKE transmitter or a known good RKE transmitter (that has been programmed to the vehicle) that is correct for the vehicle and lock and unlock the doors.
   • Do the locks lock and unlock correctly? 
   1. YES  : REPLACE the inoperative RKE transmitter. PROGRAM all the RKE transmitter(s). REFER to Remote Keyless Entry Transmitter Programming . INFORM the customer any RKE transmitters not present need to be reprogrammed. CLEAR the DTCs. TEST the system for normal operation.
   2. NO  : Go to  I8.
8. I8 CHECK FOR CORRECT DDM OPERATION 
   • Disconnect all DDM connectors.
   • Check for:
     • corrosion
     • damaged pins
     • pushed-out pins
   • Connect all DDM connectors and make sure they seat correctly.
   • Operate the system and verify the concern is still present.
   • Is the concern still present? 
   1. YES  : INSTALL a new DDM. REFER to MULTIFUNCTION ELECTRONIC MODULES article. PROGRAM all the RKE transmitters. REFER to Remote Keyless Entry Transmitter Programming . CLEAR the DTCs. REPEAT the self-test.
   2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
