Possible Causes

RKE transmitter battery
RKE transmitter programming
RKE transmitter
Aftermarket systems
High power devices
TV/radio transmission towers
SJB

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.

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

PINPOINT TEST 4		THE DOORS DO NOT LOCK/UNLOCK USING THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER
STEP	INSPECTION		ACTION
1	CHECK FOR THE CORRECT RKE TRANSMITTERS Check that the correct RKE transmitters are used with the vehicle. Make sure the RKE transmitters are the originals provided with the original equipment manufacturer (OEM) system and not from an aftermarket system, or a dealer-installed system that may have been installed on the vehicle. Are all the correct RKE transmitters present?	Yes	Go to next step.
1		No	The system cannot be tested without the correct RKE transmitters. Inform the customer that all the correct RKE transmitters need to be present to proceed with diagnosis of the system.
2	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?	Yes	The system is operating as designed. Inform the customer of the correct vehicle operation.
2		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.
3		No	See PINPOINT TEST 2: ALL DOOR LOCKS ARE INOPERATIVE , .
4	CHECK FOR THE COMPLETE FUNCTIONALITY OF THE RKE TRANSMITTER(S) Check all the RKE transmitter buttons on each transmitter for correct operation. Does the PANIC button operate correctly?	Yes	Replace the inoperative RKE transmitter. Program all RKE transmitters. see REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING . inform the customer that any RKE transmitters not present need to be programmed. Clear the DTCs. Test the system for normal operation.
4		No	Go to next step.
5	MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED Connect the IDS or equivalent tester. Enter the following diagnostic mode on the IDS or equivalent tester: SJB function tests, Transmitter test or Program transmitter. Monitor the RKE transmitter identification code (TIC) through the IDS or equivalent tester menus. NOTE: The vehicle must be electronically unlocked prior to using the IDS or equivalent tester (through the remote transmitter or door lock control switch). Verify the RKE transmitter signal is being received. Using the IDS or equivalent tester press a button on the RKE transmitter while observing the IDS or equivalent tester. Does the TIC show up on the IDS or equivalent tester screen when a button is pressed?	Yes	Go to next step.
5		No	Go to step 7.
6	CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED Enter the following diagnostic mode on the IDS or equivalent tester: SJB function tests, Transmitter test or Program transmitter. Monitor the RKE transmitter TIC/DATA through the IDS or equivalent tester menus. 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?	Yes	Go to step 8.
6		No	Replace the inoperative RKE transmitter. Program all RKE transmitters. see REMOTE KEYLESS ENTRY (RKE) 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	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?	Yes	Go to step 9.
7		No	Install a new battery (be sure the battery is seated correctly). Do not reprogram the RKE transmitters (damaged or dead batteries do not erase TICs from memory). Clear the DTCs. Test the system for normal operation.
8	CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE SJB The vehicle must be electronically unlocked prior to using any scan tools (through the RKE transmitter or the door lock control switch). Retrieve continuous DTCs through IDS or equivalent tester. Is continuous DTC B2425 stored in the SJB?	Yes	To diagnose the RKE transmitter out of synchronization, See PINPOINT TEST 5: REMOTE KEYLESS ENTRY (RKE) TRANSMITTER IS OUT OF SYNCHRONIZATION , .
8		No	Go to next step.
9	CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE TRANSMITTER Enter the following diagnostic mode on the IDS or equivalent tester: SJB function tests, Transmitter test, or Program transmitter. Monitor the RKE transmitter TIC/DATA through the IDS or equivalent tester 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 SJB. Does the TIC show up on the IDS Tester when a button is pressed on the RKE transmitter?	Yes	Replace the inoperative RKE transmitter. Program all RKE transmitters. see REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING . Inform the customer that any RKE transmitters not present need to be programmed. Clear the DTCs. Test the system for normal operation.
9		No	Go to next step.
10	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. See SMART JUNCTION BOX (SJB) , . Program all RKE transmitters. see REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING . Inform the customer that any RKE transmitters not present need to be programmed. Clear the DTCs. Repeat the self-test.
10		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.
