ABS warning light
 

Hi,
Had the front hub replaced after the nut had been left off by the previous owners garage.
New hub unit fitted but the ABS light is still on.
Does it need to be reset with a T4?
Anyone near Essex with one I could visit?
Thanks
Paul

I replaced a faulty front hub with one from scrappy as the hub reluctor ring had been damaged by garage drilling out sensor during previous owners tenure. Was gutted at first as the ABS light stayed on, took it for a short drive and ABS light went off and has stayed off.

Should not need to be reset. However it is not necessarily the sensor...

If the light comes on with the ignition and goes out, then comes on when you pull away then the plug, wiring, sensor head or reluctor ring may be at fault.

If it comes on and stays on then the ABS pump / valve, is a favourite

Hi Paul,

Before you do anything else, you did have a Navall3 didn't you ?

If so you may need to snip a wire off from the loom which has been found to cause the abs warning light to come on.

I'll post the picture of the offending wire on here when I get to work.

The black wire pointed at in the photo needs to be snipped off the connector :)

I was fitting a dashcam and my abs light was on after... it was just the fuse ... may be worth checking

Are you completely sure on that point?

I call that the first stage diagnostics/ the static stage diagnostics. My understanding is that during that first stage, the basic static operation of the sensor is tested. Unplug a sensor, or fit a faulty one and the light will remain on.

If it comes on and goes out Harry then the static test has passed (i.e. the wiring loop is complete to each sensor so plugs etc should be ok).
If the light comes on and stays on then some part is open circuit or ecu / modulator issue
If the light goes out then comes on after pulling away then at least 1 of the ABS sensors is not returning the pulses in line with the others which points to sensor head / Reluctor ring on at least 1 wheel....

Thanks
 

Hi,
Thanks for all the replies.
Jeff this is my recent addition to the fold. I purchased a cdti tourer :-)

Ok, the o/s/f hub and bearing I just had taken off was completely knackered and wobbling(no hub nut on :eek:)
The magnetic ring had worn off.
ABS light was on.
Replaced with second hand hub unit and sensor from Sean.
Light comes on and stays on. Only moved the car a little forward and back to pump peddle. Not driven it properly yet.

Understood Paul,

I forgot you had bought a new toy;)
