Hi everyone hoping for some help i have a x type diesel 05...

It recently had a bang on front corner after bang no electrical issues what so ever still started first time every time and all instruments worked a friend of mine who works at a body shop and said he would do repair but i would have to have dash and screen removed this was done body repair carried out car returned and screen and dash re fitted only to have these problems sat nav system powers up wiper work fans do not and reverse lights are permanently on if i unplug the climate control module in the drivers foot well reverse lights go out plug it back in they come back on,also when we put key in instrument panel/clock is totally dead and when we turn key to start position again nothing no clicks no power as i say nothing was really hoping someone could point me in the right direction or tell me where we could get a wiring diagram to see if this would help,we have had the dash back out rechecked connection checked for bent pins etc but nothing please help !!!!!

Why did you have to remove screen and dash for a front corner repair? Was it a major bang? Has the car been welded or on a Jig? Which corner was it?

I would check connections at ECM (Under bonnet, drivers side bulk head) and follow that loom that goes down inner wing, round the front low down under car, and back up the other inner wing to a junction box. There are some pretty important wires in there including CAN circuit between ECM and Instrument Cluster I think. Look for damage especially where body shop may have been hammering or pulling.

I brought one of these 'JAGUAR X TYPE CD-Rom Workshop Manual (NOT JTIS) >2009' from eBay for 99p a few weeks ago, it has an electrical cartoon, it may help.

When you say ignition totally dead do you mean ignition lights when turning the key? If your wipers are working then ignition switch must be good?

I had a look at wiring diagrams. Lets start with just the instrument cluster. It receives switched power like this

Battery -> Fuse39(under bonnet) -> Fuse31 (Pass Footwell) -> Ign Switch -> Fuse54 (Pass Footwell) -> Inst Cluster Pin 11 (don't know which of the 2 connectors)

Also receives non switched power like this

Battery -> Fuse39(under bonnet) -> Fuse46 (Pass Footwell) -> Inst Cluster Pin 7 (same connector)

You should check these power paths for continuity to help narrow down where the problem may be.

Sorry there's a typo mistake in my previous message. The non switched power to the cluster is through Fuse 45 not 46. So it should be

Battery -> Fuse39(under bonnet) -> Fuse45 (Pass Footwell) -> Inst Cluster Pin 7 (same connector)

I've also sent you a PM.
