Power Locks: Testing and Inspection

On models without the Remote Keyless Entry (RKE) option, proceed directly to the Door Module diagnosis. As a preliminary diagnosis for models with the RKE system, note the power lock system and illuminated entry 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 entire power lock system fails to function with either the power lock switches or the RKE transmitter, see the Body and Frame/Locks/Power Locks/Door Module diagnosis.
- If the system functions with both power lock switches, but not with the RKE transmitter, see the Body and Frame/Locks/Keyless Entry/Remote Keyless Entry Transmitter diagnosis.
- If one power lock motor fails to operate with both of the power lock switches and/or the RKE transmitter, see the Body and Frame/Locks/Power Locks/Power Lock Motor diagnosis.
- If the RKE and power lock systems are functioning, but the illuminated entry system fails to operate, see the Body and Frame/Locks/Keyless Entry/Remote Keyless Entry Receiver diagnosis.
