The complexity of the electronics involved with the instrument cluster, preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the approved Jaguar diagnostic system for detailed instructions on testing the instrument cluster circuits.
Where a fault involving the instrument cluster is indicated by the approved Jaguar diagnostic system, some basic diagnostic methods may be necessary to confirm that connections are good and that wiring is not damaged, before installing new components.
Verify the customer concern by operating the system.
Visually inspect for obvious signs of mechanical or electrical damage.
