Preliminary Diagnosis
WARNING: This page is about a different car, the 2022 Chrysler Voyager and 2022 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
As a preliminary diagnosis for the power lock system, note the system operation while actuating both the Lock and Unlock functions with the power lock switches and with the Finger Operated Button Integrated Key (FOBIK). Then, proceed as follows:
- If the entire power lock system fails to function with either the power lock switches or the FOBIK, check the fused B(+) fuse for the power lock system.
- Confirm that the Settings > Doors & Locks found in the radio show the "Flash lights with Lock" as checked. Once this is confirmed, attempt to lock/unlock with the FOBIK and look for the turn signals to flash. If the turn signals flash with a button press from the transmitter, then proceed to diagnosis of the door lock switch.
- If the power lock system functions with both power lock switches, but not with the FOBIK, proceed to diagnosis of the Remote Keyless Entry (RKE) system.
- If the power lock system functions with the FOBIK, but not with one or both power lock switches, proceed to diagnosis of the door lock switches.
- If only one power lock motor fails to operate with both power lock switches and the transmitter, proceed to diagnosis of the power lock motor.
