Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
When the problem occurs with the engine still running use your scan tool to see what modules are communicating on the network. It's most likely either the cluster, loss of power or bad ground. There are two grounds on the bracket behind the ashtray. Also look behind the driver side dash directly above the brake pedal and make sure the harness is not contacting the metal bracket creating a short.
Sorry for the delay. Looks like an internal electrical fault with the cluster. I will send over the diagram to confirm power and ground.
Here is the diagram. We have three powers pins 7, 11, and 13 and ground on pin 8. For the network with the ignition off and cluster disconnected if you ohm out the CAN pins at the cluster connector we should read 120 ohms on each leg.
Ok make sure you are on the correct connector. All are powered by seperate fuses so please double check power and ground with the ignition ON. Click on the link.
This really sounds like a problem with the cluster since we have all three powers and the one ground. CAN should read 120 since the other resistor is in the cluster
