Power Lock and Remote Keyless Entry System

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