Component Tests and General Diagnostics
1. Replace the Remote Keyless Entry (RKE) transmitter batteries. 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 receiver. Use a DRB scan tool, as described in the proper Diagnostic 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.
