abs & traction control light

[denko182]

iv had these 2 lights come on randomly,had it on diagnostics and doesnt show a fault, needed new tyres so tried new tyres but still happens, any ideas?

 

[NOT! gary l]

Are they on constantly?

 

[Da]

Serv light on too?

 

[Jamesl172]

mine tend to come on and off randomly with the service light

 

[jenic]

Dirty connections

 

[denko182]

just come on randomly,then go off the next time you start the car, and no service light either

 

[Da]

Is it usually at speed, like perhaps on a motorway or similar?

 

[denko182]

no more round town ie under 40ish

 

[Da]

Possibly an ABS sensor then.

If it's at speed/after prolonged driving it's usually the brake pedal switch.

cheers guys

Did you get this sortted? Mine is doing it still. Ive had the Break sensor out and thats fine i think

This exact issue has just happened to me when I started the car up!

 

[Da]

Could be an ABS ring or sensor, do you feel any 'clunk' from the wheels when driving?

Can't say I do. Not noticed any diff except the 3 lights coming on!

 

[Da]

Three lights? Meaning the serv light, ABS and traction control lights?

Brake pedal switch if so.

 

[Lou]

Yeah it is Da! Easy to fix?

 

[Da]

Relatively simple yeah, see here.

BREAK IN ABS PULSE RING ON THE CV JOINT CAN CAUSE A LIGHT TO COME ON, AS THE LARGE GAP BETWEEN THE TEETH CONFUSES THE PICKUP, OR A NAUGHTY SENSOR, BUT USALLY IF THAT WAS THE CASE, THE FUALT CODE WOULD BE SPEED SENSOR OPEN CIRCUIT. IF THE LIGHT NEVER GOES OUT, ITS PROBIBLY A SENSOR.

Thats what mine was , the brake pedal felt funny on my car then the lights came on.

This was the problem on my Mum's Clio. I changed the ABS ring for the princely sum of £11 :approve:

It's not as bad as it sounds.

After I stopped last night then restarted later the lights stayed off! I'll still have a look at the switch on the weekend!
