Component Tests and General Diagnostics

1. Replace the Remote Keyless Entry (RKE) transmitter batteries. (Refer to POWER LOCKS/REMOTE KEYLESS ENTRY TRANSMITTER - STANDARD PROCEDURE - RKE TRANSMITTER BATTERIES). Test each of the RKE transmitter functions. If OK, discard the faulty batteries. If not OK, go to Step 2.
2. Program the suspect RKE transmitter and another known good transmitter into the power lock and RKE module or the Central Timer Module (CTM). (Refer to POWER LOCKS/REMOTE KEYLESS ENTRY TRANSMITTER - STANDARD PROCEDURE - RKE TRANSMITTER PROGRAMMING).
3. Test the RKE system operation with both transmitters. If both transmitters fail to operate the power lock system, proceed to diagnosis of the power lock and RKE module for vehicles that are not equipped with the optional Vehicle Theft Security System (VTSS). (Refer to POWER LOCKS/POWER LOCK & REMOTE KEYLESS ENTRY MODULE - DIAGNOSIS AND TESTING). If the vehicle is equipped with VTSS, a DRB III scan tool is required for further diagnosis of the RKE system. Refer to the appropriate diagnostic information. If the known good RKE transmitter operates the power locks and the suspect transmitter does not, replace the faulty RKE transmitter.

NOTE: Be certain to perform the RKE Transmitter Programming procedure again following this test. This procedure will erase the access code of the test transmitter from the RKE receiver.
