ABS Light

[Kuran]

Ssuuppp.
So when i'm driving on the highway for longish distances the orange ABS light comes on. When i'm cruising at constant speed there is no shuddering, but when I accelerate say from 100 - 110 the car shudders a bit. Dunno if that effects the ABS at all, just saying what i know to help diagnosis. Any ideas??

You might find that one of the ABS sensors is gummed up. Also if your front rotors are warped, this can effect the ABS. Do you get a shudder when you brake?. When does the light come on. I found that if a sensor is missing the light will come on after about 300m.

Different diameter tyres, 1/2 flat tyre on the highway will put light
The shudder:check wheel nuts Check spigot rings for fit on car and mag (plastic ring in the back of the mag ,some times they fall out ten changing wheels)Or wheel weight come off.To reset abs light turn off key leave 3 min Restart if light still on Disconnect one battery lead black or neg.same 3min time replace start.

Only comes on after some time on the highway, all tyres are same pressure and diameter, all weights seem to be on. I do have warped discs though..and yeah after i reset it, as long as i'm not highway driving it stays off.
