abs and traction control lights on?

[wainie]

Hi
Ive recently bought a 2001 1.7 puma in black..........i think its a great little car for the money i paid, i bought it privately and it came with a receipt of the brakes having just been done? but both abs and traction control lights are on and wont go off, should i take it to the garage for a check? :grin:

Do you get the ABS self test when you first pull off? If you do it's likely a knackered sensor somewhere.

as soon as i turn on the ignition the light comes on and stays on........it only goes off when i turn the car off.

The ABS self test is a 'crunch' noise when you first pull off (at under 5mph IIRC)

 

[wainie]

Ahhhh right........yeah i wondered what that noise was :lol:

Crunch...nah, I like to say a Graunch....and it's at 12mph-ish

Get a mulitmeter on the ABS sensor connectors to test for resistance. Front connectors are behind the wheel arch liner, back is in the middle of the car infront of the petrol tank. (trace each connector from the sensor itself to make sure you have the right connectors). If the resistance is 1 ohm then it's ok, if it's at zero it's knackered k:

(A thought to myself, has no one done a 'How To' guide on this as it's a very regular topic :? )

Oh...and welcome to the site :thumbs:

How audible is the crunch sound of the self test? I haven't noticed it, and I've been listening for it?!

 

[yippeekiay]

You don't have to strain to hear it as it's very audible. Happens around 12mph.

I think I just heard it this morning, very short noise, a little crunchy, as you say graunchy! I think my clutch is improving through regular use, may have just been sat for too long.

Iv never ever heard mine do it tbh, maybe thats cause I have my stereo too loud

Hang on - now I'm confused. The ABS self test is supposed to happen, even if everything's OK, right? Not indicative of a knackered sensor except where the self test occurs but the dash light is on?

 

[yippeekiay]

Yes, it happens when everything is ok. I didn't realise it happens when something is wrong as mine didn't do a self test (no graunch anyway) when a sensor was broke and the lights were on.
