Telematics (G2159007): Notes

The complexities of the electronics involved with the telematics system, of which the GPS antenna and navigation display are parts, 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 approved Jaguar Land Rover diagnostic system for detailed instructions on testing the telematics system unit.

The approved Jaguar Land Rover diagnostic system tests and analyses all functions of the vehicle telematics system 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.
