Hi this is the first time I've posted on here but I've found the site very useful in the past 12 months buying and working on my 2003 L322.
Basically I've done a 2010 front end conversion on my Rangie a few months ago and all went well but as a precaution I only spliced in the new lighting connections just in case it didn't work or some parts where missing.
Anyway yesterday I started to remove the original light connections, and while cutting one of the earthing cables, the alarm well off with a constant high pitched sound, so I disconnected the alarm and carried on, but when I came to test everything again I found the error message "Air Susp Inactive" but also no interior lights, no rear window operation (front windows ok) no central locking, steering heavy. Engine will start and runs ok so I could drive it but lowered the Suspension before I started work.
I've checked all the fuses in the passenger compartment, and the boot, and I've got power to both fuse boxes.
I'm now thinking that it must be an earth fault because there's so many thing's not working but it looks like there is a supply to everything......

Any help who be appreciated

Ian
 
Post this up in the range rover section.

Youll get a better audience than general chat.

Good luck
 
Richard, I haven't because I've only cut off 100mm of cable that went to an unconnected plug so I don't belive it is forming a circuit/loop to anything else.
Big_Ginga _Beard thanks for the advice I'll repost it now

did yu cut each wire individually - coz if not, you may have shorted something :(.
 
Yeah I cut each wire one t a time then made off the joint with heatshrink sleeve over itl then moved on to the next wire.
I'm hoping to find a comon link in all the effected circuits????

The items not working (steering, locking etc) are all controlled by the body control unit under the front seat.

I'd start looking there for powers/grounds
