Wireless Door Lock Control System Diagnosis: Overview

WIRELESS DOOR LOCK CONTROL SYSTEM DIAGNOSIS:

IMPORTANT: All wireless diagnosis must start at this point and proceed as directed. Diagnostic information from this point forward assumes that all preceding steps have been properly performed. If steps are performed improperly or started beyond this point, and erroneous diagnosis may be obtained.

Start here by performing the following power door lock control and theft deterrent system checks:

1. Verify that both interior power door lock control switches will lock and unlock all doors.

2. Verify that driver and passenger door key locks will lock and unlock* all doors.

3. Verify that the theft deterrent system will arm when all doors are closed and locked.

* Driver's door key lock must be cycled twice to unlock all doors.

If any of the above items do not operate normally, refer to either the (Power) Door Lock Control System or Theft Deterrent System section of the repair manual for diagnosis. The wireless feature is an enhancement to the power door lock control system and is dependent on proper operation of the power door lock control and theft deterrent systems.
