ABS taking the michael now

[djlee]

So i've replaced the wheel hub on my drivers side front, with a genuine VX one, and the ABS light is still on, with the same fault code "Circuit Open or Low Voltage".

I should have guessed it was never going to be that easy with this stupid car, never the simplest solution!

So im over £100 lighter and i'm due for MOT, so i'm willing to have one last crack at it over the weekend before handing it over to the garage and letting them do what they have to, to fix it.

Can anyone tell me where the abs wire disappears too behind the wheel arch? Both me and the mechanic have tested the link wire for continuity and thats fine (fair play to him, he read the codes again and did a quick test on few things for free). So it must be a wiring issue further up.

So really i just need to know where it goes and how to access it. I'd like to not have to strip the side of the car down or take the bumper off if at all possible. Where about's in the engine bay does it emerge also?

Any additional advice on the best way to test the wiring would be gratefully received too

Thanks

Sounds like something could be loose or not connected?

Not sure if this is relevant to you but my ABS light came on a few weeks ago after wheel spinning on ice. No codes came up but the light would not go out even after cleaning all the connections. I disconnected the Battery to clear the ECU of any errors and hey presto the light went out and stayed out. I left the battery disconnected for around 15 mins. Give it a try you never know.

The mechanic and myself have tried clearing the code with the diagnostics machine, and it clears (light goes out) and immediately comes back within half a second. I imagine it worked for you as you essentially did the same thing (cleared the code) and didn't actually have a problem. But thanks for the reply, i might just try it anyway unless someone debunks the idea (assuming i dont need the radio code or owt with it being a full CAN).
@CRAIG: Yeah its most likely a connection/broken wire or something, i just don't know where the cable goes, and would rather not have to strip half the front of the car down in order to find out (i dont have a drive or garage to work on/in). I was hoping someone could identify either a way of accessing the wire easily or help me work out where in the engine bay it appears, so i can check all the wiring i possibly can before giving it to the mechanic (i.e. where does it plug in, or join the main loom so i can follow it back down towards the wheel).

I'm thinking beer is required tonight...

Mine was the same , checked wires for continuity and was ok but I changed the short wire anyway an it cleared it .

Swap over the n/s wire and o/s then recheck the codes , if it shows up open cubit unit on other side then it's the short wire .

£3 from breakers cured the same issue for me. I replaced the CV Joint Boots on both sides, and after this I had an ABS fault.
If only one is faulty, the speedo still works. If both have faults, then speedo, cruise control, etc does not work.
I took mine to dealer who put on diagnostic and was told I had 2 faulty ABS sensors. I didn't buy that, as all I'd done was replace the CV Boots.
I went to breakers and bought 2 Abs cables, complete from the hub to Body.
NO Fault..
Worth a try

Cheers guys, going to pop up a relatives house for a "visit" and acquire their driveway for an hour so i can have a look. Won't be able to get it up on stands, but i should hopefully be able to access what i need to, just by turning the wheels. Going to try and locate the abs pump and follow the wiring back towards the drivers front wheel and see if i can spot anything. If that fails i'll have a go at swapping the link cables around and pray.

If i fail this time, i'm just going to pop into a garage on the way back and get the car booked in for them to look at. Might end up a bit expensive to fix, but MOT's due end of the month, so i will just have to grin and bear it.

maybe someone on here who is close to you might help you out instead of putting it in a garage.

If anyone that knows what their doing wants to offer a hand, i'd gladly accept it at this point

Tried swapping the link cables over and fault was still on the drivers side, so its definitely not those. I tried checking the wiring back from the ABS module/pump, but its heavily wrapped and i didnt fancy chopping through it with just a stanley knife to hand at the time, just in case i caused any damage (although the wrapping looks in good nick, so its definitely not shorting there i don't think, and generally every time i look at a wire or connector on the car, it's usually nice and clean and good, so i'm presuming thats all fine).

Then of course the loom/wiring disappears into a metal tube that goes through the firewall (think that's what you call it?), and i can't work out where it appears again until it emerges out the wheel arch.

Hub's been changed for a genuine one, so i doubt its the sensor, i've check the link cable and thats ok too. So unless there's a break somewhere between where it disappears behind the arch and emerges in that metal tub, i haven't the foggiest.

Popped into the garage on the way back and he's got me booked in for Monday morning, so hopefully he can sort it for me (although he did say, since i've checked a lot of stuff already, it might take more than a day to find the problem). Hopefully the fact that he's checked the link cable himself, and ive already paid him to do the wheel hub (in hindsight i wish i'd asked him to test it first and save me the price of a hub lol), will mean he can start looking at the correct places more sooner and find it quicker, as i don't fancy a £400+ bill just for a stupid shorting/broken wire.

Anyone any pics of these wires or there location...

Im looking to replace the ABS module this weekend, but as the speedo, PAS and trip comp are temperamental, maybe mine is the wiring too? Did get my cv boots done few months ago and these lights have happened twice since?

What do you think @stret? Try the wires off the signum first
