Seating: Diagnosis Jaguar S-type I

Diagnosis and Testing

The complexity of the electronics involved with the seating, of which the DSM 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 Jaguar Approved Diagnostic System for detailed instructions on testing the seating.

The Jaguar Approved Diagnostic System 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.
