Component Tests and General Diagnostics

1. Replace the Remote Keyless Entry (RKE) transmitter batteries. (Refer to ELECTRICAL/ 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 RKE receiver. Use a DRB III scan tool, as described in the appropriate diagnostic information. (Refer to ELECTRICAL/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, use a DRB III scan tool and the appropriate diagnostic information for further diagnosis of the RKE system. 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.
