Diagnosis And Testing
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
The complexity of the electronics involved with the anti - theft system, 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 manufacturer approved diagnostic system for detailed instructions on testing the anti - theft system.
The manufacturer 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.
