Check your brake lights.

Can check diagnostics yourself:

Hey I got same car as you :Cool2:
Can't remember seeing a brake-lamp check-light, so won't know if a bulb is out - which causes abs light to come on.

Also check your ABS rings for cracks/worn teeth. Also check that a previous owner hasn't fit the wrong ABS ring with the wrong amount of teeth also.

Welcome to VxON btw Hope you get to the root of your problem. Keep us posted.

CALLY T sorted the abs problem out many thanks
its unbelieveable that its the lights and it dosent tell you in any manual (not any that i have) anyway tried the paperclip trick and it works a treat but only prob i got now is where is the cranlshaft sensor (which is the fault indication)on our 20l ecotec gls model as the haynes manual is not very clear

Any ideas mate

cheers Marc

Nice one :beer:

Crank sensor is easy peasy. Lie under front of car, and just above the sump, towards drivers side you'll see it, round black head and one bolt securing it.
The black cable running down side of cambelt cover is to the crank sensor, so could trace that if unsure.
Need a torx bit and ratchet, remove bolt, and prise sensor out.
Only tricky part is lining up the holes to refit bolt.
Don't even need car jacked up.

if youve got Power Steering you'll find the crank sensor is obscured by the PAS pump when looking from above.

ive just checked it out what an awkward place the hardest bit is trying to grab hold of the sensor to pull it out but i think i need a new one as the cable is all cream crackered so a quick trip to the scrappys tomorrow many thanks for your help il let you know if it cures the prob

If you do the paper clip test with the ignition on, but the engine not running, doesn't it always bring up the crank sensor code? If the crank sensor goes you get no fuel or spark.

Pry-bar or something. Get behind where cable comes out of sensor, soon comes out.

The X20XEV brings up a genuine crank sensor fault code.
