Pinpoint Test D: The Doors Do Not Lock/Unlock Using The Remote Keyless Entry (RKE) Transmitter
- D1 CHECK FOR THE CORRECT RKE TRANSMITTERS
- Check that the correct RKE transmitters are used with the vehicle.
- Are all the correct RKE transmitters present?
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.Yes : GO to D2.
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.
- D2 CHECK THE OPERATION OF THE RKE TRANSMITTER WITH THE IGNITION SWITCH IN THE OFF POSITION
- Key in OFF position.
- Check the operation of the RKE transmitter.
- Does the system operate correctly now?
Yes : The system is operating correctly. INFORM the customer of the correct vehicle behavior.
No : GO to D3.
- D3 CHECK FOR CORRECT POWER DOOR LOCK SYSTEM OPERATION
- Verify the door lock/unlock operation by activating the driver door lock control switch.
- Do all the doors lock and unlock correctly?
Yes : GO to D4.
No : GO to PINPOINT TEST B .
- D4 CHECK THE COMPLETE FUNCTIONALITY OF THE RKE TRANSMITTER(S)
- Check all the RKE transmitter buttons for correct operation.
- Does the panic button operate correctly?
Yes : REPLACE the RKE transmitter in question. PROGRAM all RKE transmitters. REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING in this article. INFORM the customer that any RKE transmitters not present must be programmed. TEST the system for normal operation.
No : GO to D5.
- D5 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED NOTE: The vehicle must be electronically unlocked prior to using any scan tools (through the RKE transmitter or the door lock control switch).
- Key in ON position.
- Enter the following diagnostic mode on the scan tool: SJB Function Tests, Transmitter Test or Program Transmitter.
- Monitor the RKE transmitter identification code (TIC) through the scan tool menus.
- Verify the RKE transmitter signal 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?
Yes : GO to D6.
No : GO to D7.
- D6 DETERMINE IF THE RKE TRANSMITTERS ARE PROGRAMMED
- Enter the following diagnostic mode on the scan tool: SJB Function Tests, Transmitter Test or Program Transmitter.
- 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 the back of the RKE transmitter match any of the TICs stored in memory?
Yes : GO to D8.
No : PROGRAM all of the RKE transmitters. REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING in this article. INFORM the customer that any RKE transmitters not present will need to be reprogrammed. TEST the system for normal operation.
- D7 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?
Yes : GO to D9.
No : INSTALL a new battery. MAKE SURE the battery is seated correctly. Do not program the RKE transmitters (damaged or dead batteries do not erase TICs from memory). TEST the system for normal operation.
- D8 CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE SJB
- Retrieve continuous DTCs with the scan tool.
- Is continuous DTC B2425 stored in the SJB?
NOTE: The vehicle must be electronically unlocked prior to using any scan tools, through the RKE transmitter or the door lock control switch.Yes : GO to PINPOINT TEST E
No : GO to D9.
- D9 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE TRANSMITTER
- Enter the following diagnostic mode on the scan tool: 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.
- Does the TIC show up on the scan tool when a button is pressed on the RKE transmitter?
Yes : REPLACE the inoperative RKE transmitter. PROGRAM all RKE transmitter(s). REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING in this article. INFORM the customer that any RKE transmitters not present need to be programmed. TEST the system for normal operation.
No : GO to D10.
- D10 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.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . PROGRAM all the RKE transmitters. REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING in this article. INFORM the customer that any RKE transmitters not present need to be programmed. TEST the system for normal operation.
No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
