Possible Causes

PINPOINT TEST 5: DOORS DO NOT LOCK/UNLOCK USING KEYLESS ENTRY REMOTE TRANSMITTER

PINPOINT TEST 5 THE DOORS DO NOT LOCK/UNLOCK USING THE REMOTE TRANSMITTER
STEP INSPECTION ACTION
1 CHECK FOR THE CORRECT REMOTE TRANSMITTERS
  • Check that the correct remote transmitters are used with the vehicle.
  • Make sure the remote transmitters are ones provided with the OEM system and not from an aftermarket or a dealer-installed system that may have been installed on the vehicle.
  • Are all the correct remote transmitters present? 
 Yes Go to next step.
No The system cannot be tested without the correct remote transmitters. INFORM the customer all the correct remote transmitters need to be present to proceed with diagnosis of the system.
2 CHECK THE OPERATION OF THE REMOTE TRANSMITTER WITH THE KEY IN THE OFF POSITION
  • Key OFF.
  • Check the operation of the remote transmitter.
  • Does the system operate correctly now? 
 Yes The system is operating as designed. INFORM the customer of the correct vehicle behavior.
No Go to next step.
3 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? 
 Yes Go to next step.
No To diagnose the inoperative door locks, See PINPOINT TEST 1: ALL DOOR LOCKS ARE INOPERATIVE  .
4 CHECK FOR COMPLETE FUNCTIONALITY OF THE REMOTE TRANSMITTER(S)
  • Check all the remote transmitter buttons for correct operation.
  • Does the panic button operate correctly? 
 Yes REPLACE the remote transmitter.
REPROGRAM all remote transmitters. See HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS . INFORM the customer any remote transmitters not present will need to be reprogrammed. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
No Go to next step.
5 MAKE SURE THE REMOTE TRANSMITTER SIGNAL IS BEING RECEIVED
  • Connect the WDS or equivalent Tester.
  • Monitor the remote transmitter identification code (TIC) through the WDS or equivalent Tester menus.
    NOTE:
    • The vehicle must be electronically unlocked prior to using any diagnostic tools (through the remote transmitter or the door lock control switch).
  • Verify the remote transmitter signal is being received. Using the WDS or equivalent Tester, press a button on the remote transmitter while observing the WDS or equivalent Tester.
  • Does the TIC show up on the WDS or equivalent Tester screen when a button is pressed? 
 Yes Go to next step.
No Go to step 7.
6 CHECK IF THE REMOTE TRANSMITTERS ARE PROGRAMMED
  • Monitor the remote transmitter TIC/DATA through the WDS or equivalent Tester menus.
  • Verify the remote transmitters are programmed to the vehicle.
  • Does the TIC displayed under remote transmitter match any of the TICs stored in memory? 
 Yes Go to step 8.
No REPROGRAM all of the remote transmitters. See REMOTE TRANSMITTER PROGRAMMING . INFORM the customer that any remote transmitters not present will need to be reprogrammed. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
7 CHECK THE REMOTE TRANSMITTER BATTERY
  • Using a thin coin, open the remote 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 remote transmitter battery and measure the voltage.
  • Is the voltage greater than 2.5 volts? 
 Yes Go to step 9.
No INSTALL a new battery (be sure the battery is seated correctly). Do not reprogram the remote transmitters (faulty or dead batteries do not erase TICs from memory). CLEAR the DTCs.
REPEAT the self-test. TEST the system for normal operation.
8 CHECK IF THE REMOTE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE SJB
NOTE:
  • The vehicle must be electronically unlocked prior to using any diagnostic tools (through the remote transmitter or the door lock control switch).
  • Retrieve continuous DTCs via the WDS or equivalent Tester.
  • Is continuous DTC B2425 stored in the SJB? 
 Yes To diagnose the remote transmitter out of synchronization, See PINPOINT TEST 6: REMOTE KEYLESS ENTRY TRANSMITTER OUT OF SYNCHRONIZATION  .
No Go to next step.
9 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD TRANSMITTER
  • Monitor the remote transmitter TIC/DATA through the WDS or equivalent Tester menus.
  • Using the customer's second remote transmitter or a known good remote transmitter that is correct for the vehicle, verify the remote transmitter signal is being received.
  • Does the TIC show up on the WDS or equivalent Tester when a button is pressed on the remote transmitter? 
 Yes REPLACE the inoperative remote transmitter. REPROGRAM all remote transmitter(s).
See REMOTE TRANSMITTER PROGRAMMING . INFORM the customer any remote transmitters not present will need to be reprogrammed. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
No Go to next step.
10 CHECK THE SJB FOR CORRECT OPERATION
  • Disconnect all the SJB connectors.
  • Check for:
    • corrosion
    • 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? 
 Yes INSTALL a new SJB. See SMART JUNCTION BOX (SJB) .
REPROGRAM all the remote transmitters. See REMOTE TRANSMITTER PROGRAMMING . INFORM the customer any remote transmitters not present will need to be reprogrammed. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
No The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
