Title: Intermittant ABS TC and speedo fault?
Post by: Del Boy on 23 November 2006, 15:59:57
Well guys the ABS and TC light came on and about the same time the speedo stopped working got a about 2 miles down the road and the lights went off and speedo came back to life then lights flickered on then went off I'm guessing a dirty sensor do you know where they are located or any other ideas of what this fault could be? facelift 3.0MV6
cheers Liam :y

Well if its speedo related then its most likely one of the rear sensors.....check also the plug on the main ABS ecu (end of the modulator on the passenger side of the engine bay)

Sorry to be possible bearer of bad news, but every one I've seen with this fault has needed a new ABS ECU :(

Not a mini facelift or very early facelift by any chance?

I've heard of a company selling recon ones for a couple of hundred, but they tend to have faults on as well :(
Title: Re: Intermittant ABS TC and speedo fault?
Post by: TheBoy on 23 November 2006, 17:17:09
Also, if you do have to replace, ensure you get right one - you'll probably need ident code off old one.

The unit itself is around £300 + VAT, and you would be looking at least the same again to fit it.

There is a "how to" in the maintenance guides on here.

Deffo not a fun job though.

Yeah 1998 MV6. Generally the cars affected are VIN range "W10000001" onwards when they modified the ABS system.

Had this fault earlier in the year, cleaned the sensors first off, then the general concensus was the ABS ECU  shagged, still got the fault (who needs a speedo, saves switching the TC off every time you get in the car!)

It will be the difference between a years ticket, and one of those nasty fail tickets.

LSG 1 did you have a look at your sensors and plug at abs unit? Also for anyone, had a problem with cdc safe on my radio which I still have but I took my radio out and have basically had this problem since just after that, also my rear passengers side electric window has stopped working. Now is the abs tc speedo thing a coincidence or could I have disturbed something around the radio that could have give me the abs tc speedo problem and rear window problem? Also have lost power steering a couple of times when starting the car then it just starts working again within a minute

Also TB ABS only stops the brakes locking up but with older cars that don't have ABS they can still pass so how does this work :-?

Hi paulr.
Quite a few vehicles now have a stereo system that is fed the road speed signal from the ABs sensors (or others).  This enables the stereo to increase in volume as the road speed/noise increases.  This was one of the main selling points on the advert for the Vectra a few years ago!  Since the speedo, cruise, TC and ABS use this signal, they all go down.  At the moment, many people are changing stereos, plugging the new (non compatible) ones in, and causing major problems.  When expensive scanners are plugged in to check for fault codes/live data, the electrical shorts caused by the new stereo are destroying the scanners (lives are appearing at the EOBD socket where they shouldn't be).  Quite a few garages now won't touch a car with a non genuine stereo system in it without it being disconnected first.

Andy.

Guys relating to what andyfanshawe just said the wife was saying she was playing with my stereo and this has only happened since she has done this i dont think that this mode is still on but if it was on would this affect my car?

Mine only started after I had taken the cd player out and put it back in. I took it out to check the connection inbetween the 2 units (ccr2006 radio) as it was saying cdc safe

Post by: andyfanshawe on 07 December 2006, 22:13:34
Hi Paulr
Pull that CD player out again and check all multiplugs are fully in.  Pull ecah one out and push back in until they click.  Make sure you don't miss any and no pins are pushed out as the plug is pushed in (if you know what I mean!).

Andy.

Post by: paulr on 07 December 2006, 22:39:32
Hi andy, the multi plugs should be in as they are attached  to the cage the radio goes into. Might be an idea to check the pins are straight though.
Car had its MOT today and luckily the abs tc lights didn't come on so very happy about that  ;D just gotto replace the abs ecu and radio now  :( Abs Unit (ECU) 9117171 £283.66 inc VAT CCR2006 9119984 £326.65 inc VAT
