well have you cleaned your sensors ?

this would be a good place to start as th road dirt can affect the sensor and cause the system to so a fault. the back ones are really easy to clean on an estate and the fronts can be a pain in the but to remove.

i took mine out and cleaned them i also jet washed the underside of the car as the area where the sensors fit was also very dirty.

start with this and if you get no joy we can look at the next thing. your welcome to pm me. :)

clean abs sensors ........... will try that when i get a chance  :y

cheers marie

brake light bulb's ? will do but you lost me on that one mark.

me being a sparky.  ( house and aircraft )

why bulb's ?  :o

Because if the bulbs have gone then the ABS unit can throw a wobbly as the bulb filaments work as the pull down to 0V.

ok i just checked the bulbs ............. all ok

did a clip test a few weeks ago ( when i had the missing / backfiring fault )      the only code it threw up was tell tail check light (52)

could these be related ?

paperclip test only looks at engine, not abs.

What year is the car?

Is your car 1998 - ?
Does the speedo still work while abs light on.  Is TC light on as well?

First action as above - check/clean abs sensors.

cars on a p plate (96/97)

i have noticed the speedo seams to over read by about 3 - 4 mph (acording to my sat nav )

also the fuel gauge never reads above 60 ltrs.
any conection ?

Post by: Jimbob on 15 April 2009, 08:01:16

every speedo overreads

all seem to be about 3-4 mph too high

Title: Re: abs / traction control lights
Post by: Marks DTM Calib on 15 April 2009, 08:30:29

And satnav generaly under reads due to the methods used to calculate the speed from the GPS position

dbug ........ abs/tc lights always come on together on this fault

I am new to this Omega lark, my last Vauxhall was a 1985 2.5i Senator A but now my gorgeous 2000 MV6 Estate has what seems to be this issue, the Speedo does not work and the ABS and TC lights are on, to cap it the engine management light came on yesterday! All the fluids are okay and the car drives, starts and stops fine! Any ideas?

Just a though but I had a simular issue on a Vectra B.

Turned out it wasnt the ABS sensors but the actual ABS ring on the front driveshaft.

Its a ring thats pressed onto the shaft ( bit like a ring gear on a flywheel ) and it had split so no longer fixed to the shaft. Its confused the hell out of the ABS system and threw  up all sorts of issues.

Might be worth giving the rings a clean and see if they are loose on the shaft.

Just my 2p  ;D

dbug ........ abs/tc lights always come on together on this fault

Possibly breaked abs ecu - symptoms abs and tc lights on together, speedo stops working and steering may get heavy (speed sensitive power steering).  Check/clean abs sensors first and pray that cures it as changing the abs ecu is a right barsteward >:( - been there done that.

If speedo is not working with the abs/tc lights on the defo ABS/TC ECU failure...if just the lights on then may well just be dirty sensors :y

Changing the ECU really isnt that hard if you do it a little differently  ::)
