Testing

On models without the Remote Keyless Entry (RKE) option, proceed directly to the Power Lock Switch diagnosis. As a preliminary diagnosis for models with the RKE system, 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 system fails to function with either the power lock switches or the RKE transmitter or if the illuminated entry fails to operate, see the Power Lock and Remote Keyless Entry Module diagnosis.
- If the system functions with both power lock switches, but not with the RKE transmitter, see the Remote Keyless Entry Transmitter diagnosis.
- If the system functions with the RKE transmitter, but one or both power lock switches is inoperative, see the Power Lock Switch diagnosis.
- If one door lock fails to operate with the power lock switches or the RKE transmitter, see the Power Lock Motor diagnosis.
