Hi Guys,
The Hydractive ECU (H5) on my XM isn't getting any power.
I have checked the fuse that is mentioned in the handbook and Ciaran has also advised me to check the ones that act on the deadlock as this caused problems with his suspension also.
After checking the two of these I am not getting any power at all to the ECU.
I have remade all of the earth clamps that go to the inner wing also just incase it was one of those that was causing problems.
I just wondered if anybody else had experienced any problems similar to this and could advise me where to check next?
If it makes any difference it is a 1998 V6 Exclusive.
Regards
David.

Mr Haynes isn't a lot of help but I do have a circuit of the suspension ECU which doesn't help as much as it should. What it does tell me though is that Fuse 34 is the 12v supply and also that the 12v feed to the main IC in the ecu is on pins 1&2. It enters the unit at a point labelled 11N A4 if that means anything to you. If you can identify the feed point, as has already been suggested, run a new supply.
