Test A: Keyless Entry System Inoperative

NOTE:

Reviewing system description and operation information will help determine if condition described by customer is normal operation, and may help determine correct symptom diagnostic procedure when a malfunction exists. See DESCRIPTION & OPERATION . Perform a preliminary inspection before proceeding. See PRELIMINARY INSPECTION under TROUBLE SHOOTING.

If Remote Keyless Entry (RKE) system diagnostic system check has been performed, go to next step. If diagnostic system check has not been performed, go to REMOTE KEYLESS ENTRY SYSTEM DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.
Operate transmitter within range of vehicle. If all RKE functions do not operate normally, go to next step. If all RKE functions operate normally, go to DIAGNOSING INTERMITTENTS .
Check power door locks function using door mounted switch. If power door locks function properly, go to next step. If power door locks do not function properly, repair as necessary. See appropriate POWER DOOR LOCKS article.
Check trunk release function using instrument panel mounted switch. If trunk lid release functions properly, go to next step. If trunk lid release does not function properly, repair as necessary. See appropriate POWER REAR COMPARTMENT & FUEL DOOR RELEASE SYSTEMS article.

NOTE: Inspect keyless entry transmitter to ensure it is correct model for this vehicle. A wrong model transmitter may pass this test, but will not activate vehicle remote system.

Turn on Keyless Entry Tester (J43241). Place transmitter on keyless entry tester pad. Press each button of transmitter one at a time. If a tone does not sound or Green light does not illuminate after each button is pressed, go to next step. If a tone sounds and Green light illuminates after each button is pressed, go to step 10 .
If no buttons sound tone or illuminate Green light in step 5 , go to next step. If any button sounds tone and illuminates Green light, go to step 9 .
Replace transmitter battery. See TRANSMITTER BATTERY under REMOVAL & INSTALLATION. After repair, go to next step.
Turn on keyless entry tester. Place transmitter on keyless entry tester pad. Press each button of transmitter one at a time. If a tone does not sound or Green light does not illuminate after each button is pressed, go to next step. If a tone sounds and Green light illuminates after each button is pressed, go to step 10 .
Replace RKE transmitter. After repair, go to step 13 .
Press PANIC button on transmitter. If PANIC function operates normally, go to next step. If PANIC function does not operate normally, go to step 13 .
Resynchronize transmitter. See TRANSMITTER RESYNCHRONIZATION under PROGRAMMING. If horn chirps 3 times to confirm that synchronization has been completed, go to next step. If horn does not chirp 3 times to confirm that synchronization has been completed, go to step 13 .
Operate transmitter within range of vehicle. If all RKE functions do not operate normally, go to next step. If all RKE functions operate normally, go to step 26 .

NOTE: All transmitters which are to be recognized by RCDLR must be programmed in a single programming sequence.

Program transmitter. See TRANSMITTER PROGRAMMING under PROGRAMMING. If Body Control Module (BCM) does not chime 3 times to confirm that programming has been completed, go to next step. If BCM chimes 3 times to confirm that programming has been completed, go to step 26 .
Turn ignition switch to OFF position. Disconnect Remote Control Door Lock Receiver (RCDLR) harness connector. Connect a test light between ground and RCDLR harness connector terminal "C" (Orange wire). See Figure . If test light illuminates, go to next step. If test light does not illuminate, go to step 21 .
Connect a test light between RCDLR harness connector terminal "A" (Black wire) and terminal "C" (Orange wire). If test light illuminates, go to next step. If test light does not illuminate, go to step 22 .
Disconnect test light. Turn ignition switch to RUN position. Using a DVOM, measure voltage between RCDLR harness connector terminal "A" (Black wire) and terminal "E" (Light Green wire). If any voltage is present, go to next step. If no voltage is present, go to step 18 .
Turn ignition switch to OFF position. Connect a test light between RCDLR harness connector terminal "A" (Black wire) and terminal "E" (Light Green wire). Turn ignition switch to RUN position. If test light does not illuminate, go to step 19 . If test light illuminates, go to step 23 .
Test Light Green wire between RCDLR and BCM for an open, high resistance or short to ground. See WIRING DIAGRAMS . If an open, high resistance or short to ground is not found, go to step 20 . If an open, high resistance or short to ground is found, repair as necessary. After repair, go to step 26 .
Check RCDLR connector for poor connections. If poor connections are not found, go to step 24 . If poor connections are found, repair as necessary. After repair, go to step 26 .
Check BCM connectors for poor connections. If poor connections are not found, go to step 25 . If poor connections are found, repair as necessary. After repair, go to step 26 .
Repair open, high resistance or short to ground in Orange wire between fuse block and RCDLR. See WIRING DIAGRAMS . After repair, go to step 26 .
Repair open or high resistance in Black wire between RCDLR and ground point. See WIRING DIAGRAMS . Ground point is located below instrument panel, to right of steering column. After repair, go to step 26 .
Repair short to voltage in Light Green wire between BCM and RCDLR. See WIRING DIAGRAMS . After repair, go to step 26 .
Replace RCDLR. See REMOTE CONTROL DOOR LOCK RECEIVER under REMOVAL & INSTALLATION. After repair, go to step 26 .
Replace BCM. See BODY CONTROL MODULE under REMOVAL & INSTALLATION. After repair, go to next step.
Operate system to verify repair. If system does not operate normally, go to step 3 . If system operates normally, system is okay.
