Door Lock Cylinder Switch: Testing and Inspection

DIAGNOSIS AND TESTING - DOOR CYLINDER LOCK SWITCH - EXPORT

Any diagnosis of the power lock system should begin with the use of the scan tool.

For complete circuit diagrams, refer to the appropriate wiring information.

1. Visually inspect the switch for proper installation. Make sure it is seated on the rear of the key cylinder, with the tab of the door key cylinder properly aligned with the slot on the door cylinder lock switch.

2. Disconnect the switch at the harness connector and check the resistance in each switch position.

CAUTION:
Do not disconnect the switch from the rear of the door key cylinder. This switch is a one time use switch. Once it is removed from the rear of the switch, it is not reusable and must be replaced. Test the switch at the harness connector.
