Anti-Theft Security Access
The complexity of the electronics involved with the anti theft, of which the security access is a part, and the multiplexed communication network which are connected to it preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the WDS User Guide for detailed instructions on security access. The WDS systematically tests and analyses all functions and the various systems affected by it. Where a fault is indicated, some basic diagnostic methods may be necessary to confirm that connections are good and that wiring is not damaged before installing a new component.
Key Programming Using Diagnostic Equipment
