And thank u sierraferry I did understand after reading those pdfs properly

Hallelujah SHE RUNS , I'd had a mouse visitor previous owner had left loads of blue roll after wiping dipstick next to fuse box and said mouse was starting to make a nest and the only wire it had eaten was the return fro. The inertia switch! Thanks for everyone's help I still have no alarm at...

I got all the wiring colours n diodes bulbs resistors n stuff but can't work out how the naming of the plugs work , they're mentioned a lot but I can't find a " map" or location list to know where to start , a few are obvious but not all ?

I got the map of under box thanks at least those are clearly marked!

Also as u said not all the wires in the diagrams are correct , which does your nut when not an expert.

I have problems identifying the plugs refered to by the numbers .... how does that system work?

Right I may have figured this out I just wanna check with u lot! There is no continuity between white / green stripe wire coming from inertia switch , to either of the small spades on the main relay. There is power at inertia switch and continuity.. So I believe I have a broken wire to the main...

Yup got a 12.6 positive out of the feed to inertia switch and the fuse is good obviously I've def got power coming in to main relay on 1 of the big spades when I joined that to the other 'big' spade ecu could be read and fuel pump ran (when key turned ) Should I get a positive signal at 1 of...

I just understood what u meant then ill check thru that file.ta

It didn't start from inertia being bridged , I bridged the 2 bigger spades on the main relay , then fuel pump worked.but still activating M and S and hazards

In the bcu it said I only had 12.1 volts in battery but my multimeter says 12.6 volts? I've put it on charge again.....

I have finally got into slabs and the bcu So no slabs action at all But bcu is telling me stuff , like I'm moving gearstick from park to neutral but it says most stuff is off I repaired the xyz switch a while ago and have had no probs with that since. In bcu it mentions a W switch as well ...

Bridged relay and pump ran so no prob with pump. I guessed ace would be OK, I'm trying to learn what the body control unit does it seems to do alot thought it might involve the ace too

Oh maybe I should mention , I de aced it a little while ago but had no probs after that apart from the ace light being amber, would this affect it?

Charged battery to full, checked and reset inertia switch then bridged to check, Thing is it still cranks so only half dead? . So yeah not immobilised but sort of? I'm not very clever with nano coming only learning but , it powers up but don't connect .....

Hi I have an auto disco2 I did head gasket took a few days due to bits n bobs snapping Battery disconnected for 5 days , when I tried to start fuel pump won't prime , she turns over but x and s lights flash when at position2 on ign and hazards go on Nano com won't talk to ecu Have tried all...

I found it ta

Could someone explain how to get to the disco section I've tried but no joy yet!

No jump starting charged on and off the vehicle , and ive tried the battery strap trick Thanks kermit I'll try the other bit (I'm not very digitally savvy)
