Title: abs ecu intermittent fault
Post by: kris9128 on 21 September 2008, 18:01:14
hi all. need to pick your brains for a little while. have a slightly annoying fault on the abs ecu. the fault only happens once the engine gets upto running temp then comes and goes at will. have dis/re-conected ecu but faults is still there. any body got any ideas.

Do you mean ABS & TC lights come on? Is speedo still working at the time they're on?

Suggest this is a knackered ABS ECU - it won't get any better only worse!  Search for ABS ECU - there's lots of help/comment on here.

lose speedo, cruise, tc,abs and power steering at same time. it only started recently when i fitted new alternator. vx think i disturbed somthing whilst disconnecting battery but want to charge fortunes to fix it. always like to get a second opinion where vx dealers are concerned tho.

Hi Kris,

That happened to mine when I used jump leads once.  Vx will charge a fortune for a new ABS ECU.  

However there's a company in Kent that will rebuild them for around £130 if my memory serves me right.  The downside is that it takes the car off the road for a few days as you have to take it out and post it off to them, but thats better than the ££££££££££'s that Vx will happily charge......

Can't remember what the company is called offhand, but a search on here should uncover it, if you have no joy get back to me and I'll go through my receipts.

Good Luck

Steve ;)

Other option is to buy second hand one (I paid about £40 for one).  Best to get one off exactly same year & model as yours else will require reprogging with Tech2.

Confirm you will lose anything "speed related" - thats power steering + cruise.

Give bba-reman a ring .. they sorted mine out.. couriered the knackered one to them on Monday, they rang with the test results and a price for fixing Wednesday, after giving the go-ahead the unit arrived back on the Friday

That was 15 months ago, cost was £130 ... well impressed  :y :y

The common ABS fault only seems to affect 1998 and later cars. As yours is a 1997, I would get a tester plugged in and go from there.

Most likely to be a front wheel sensor at a guess.

As a general thing, having now taken one of these faulty modules apart, I can not see much that could be serviced on them as the main PCB is a true hybrid so pretty much un-touchable!.

There are two relays that might be an issue plus a load of welded type contacts which have also been known to be problematic.

So, if anybody has a failed unit I would like to try a repair on one of these (the original one I have has been sacrificed to get this far!)

On a 1996 2.0l which tech2 said ECU failed, I managed to get it working (as a temp fix) by taping relays with screwdriver handle.  As far as I know, it lasted some time, probably still is OK.  So sticky relays does sound a possibility.

From memory, think it was Nixoro's car, so if he is still around to comment?
