Flow of Diagnosis

NOTE: Keep the driver window rolled down during any inspection or pinpoint test to avoid being locked out of the vehicle.

1. Verify the original concern by operating the Remote Keyless Entry (RKE) system to duplicate the concern.
2. Before proceeding with diagnosis and testing of the electronic door lock control system electrical operation, check for mechanical binds in the door locks. Operate all door locks several times and check the lock operation. Also be sure the battery is fully charged.
