Power Locks: Testing and Inspection

As a preliminary diagnosis for the power lock and Remote Keyless Entry (RKE) systems, note the system operation while you actuate both the Lock and Unlock functions with the power lock switches and the RKE transmitter. Then, proceed as follows:
- If the power lock system fails to function with either the power lock switches or the RKE transmitter, see the Circuit Breaker diagnosis.
- If the power lock system functions with both power lock switches, but not with the RKE transmitter, see the Remote Keyless Entry Transmitter diagnosis.
- If the power lock system functions with the RKE transmitter, but not with one or both power lock switches, see the Door Module diagnosis.
- If one power lock motor fails to operate with the power lock switches or the RKE transmitter, see the Power Lock Motor diagnosis.
