Initial Inspection and Diagnostic Overview

The door lock system is modular in design. With this type of design, all the parts are contained in one unit (the module assembly). The entire module assembly is removed when repair to any component is required. The exception is the power lock actuator which can be serviced on the vehicle. In order to properly evaluate the lock system after replacement part has been installed, the following operational checks should be made:

Inspect
1. Insert key into cylinder. While holding key in the neutral (pull out) position, actuate the inside locking button to the fully locked position and back to the fully unlocked position. There must be no forced movement of the key out of neutral position during the entire cycle. The key must be removable when the inside locking button is held in both the fully locked and unlocked positions.

2. Turn key to fully locked position and return it to the neutral (pull-out) position. Actuate both outside and inside handles to ensure the door will not open.

3. Turn key to the fully unlocked position and return it to the neutral (pull-out) position. Actuate both outside and inside handles to ensure door will open.
