Power Locks: Testing and Inspection

The driver and passenger lock switches are wired in parallel and form one input to the entry module.

When the entry module receives a lock input, both doors are locked.

When an unlock signal is input to the entry module, both doors are unlocked.

If the key is ON, and an inside door handle input is seen and vehicle speed is below 8 Km/h (5 mph), both doors will be unlocked. The lock switch is a momentary contact type switch and either door switch will lock or unlock both doors.

For complete testing of the power door locks and electric latches, refer to the proper Body Diagnostic Procedures.
