Preliminary Diagnosis

As a preliminary diagnosis for the power lock system, note the system operation while you actuate both the Lock and Unlock functions with the power lock switch and with the Remote Keyless Entry (RKE) transmitter. Then, proceed as follows:

1. If the entire power lock system fails to function with either the power lock switch or the RKE transmitter, check the fused B(+) fuse for the power lock system in the Power Distribution Center (PDC).
2. If the power lock system functions with the power lock switch, but not with the RKE transmitter, proceed to diagnosis of the RKE system.
3. If the power lock system functions with the RKE transmitter, but not with the power lock switch, proceed to diagnosis of the door lock switch.
4. If only one power lock motor fails to operate with the power lock switch and the RKE transmitter, proceed to diagnosis of the power lock motor.
