Component Tests and General Diagnostics

RKE TRANSMITTER TESTING
1. Replace the Remote Keyless Entry (RKE) transmitter batteries. See Remote Keyless Entry Transmitter Battery Replacement in the Service Procedures. Test each of the 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 module. Use a DRB scan tool, as described in the proper Diagnostic Procedures. See Remote Keyless Entry Transmitter Programming in the Service Procedures.
3. Test the RKE system operation with both transmitters. If both transmitters fail to operate the power lock system, use a DRB scan tool and the proper Diagnostic Procedures for further diagnosis of the RKE system. If the known good transmitter operates the power locks and the suspect transmitter does not, replace the faulty transmitter.

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