Theory of Operation
This code will only set in vehicles that have the Memory System. The supply circuit for the Memory Mirrors are
supplied by the Memory Mirror Module, therefore both the Memory Select Switch Mux or the Door Lock Switch Mux
circuits can cause this DTC.
Diagnostic Test

Operate the Door Lock Switch from the side this DTC was set in. Put
the switch in both positions several times.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read DTC’s.
Does the scan tool display DOOR LOCK/UNLOCK SWITCH CIR-
CUIT STUCK UNLOCK?
Yes
>> Go To 2
No
>> The conditions that caused this code to set are not
present at this time. Using the wiring diagram/schematic
as a guide, inspect the wiring and connectors.
