This happens when the car is cold. Seems worse in colder weather.

Start the car, drive about a block, hit the brakes and these three lights come on accompanied by three beeps. Usually occurs with the first stop or two after the car is in motion. Shift to park, stop and restart the car, all lights clear but the ABS light. Drive, and the ABS light clears once over 10 mph or so. A stop or two later, problem repeats. Restart car again ... etc ...

This cycle continues three or four times until the car warms up and I have driven a couple of miles (in the city, so a lot of stops).

Anyone heard of this particular electrical demon before and, more importantly, have an appropriate exorcism procedure?

Seems to me like a sensor is going bad somewhere, but where I have no idea.

Thanks,

Bob

 

I have heard of it before, when was the last time you chamged the brake fluid?
Yes it could be a speed sensor or the ABS unit itself, will be hard to tell till the light stays on and codes can be read.

My Rover guy was able to read my "three lights" codes without the lights actually being on. He said that those codes would store until cleared.

 

My 2004 is doing the EXACT same thing. Im taking it in to be serviced next monday. I will let you know what they say. One thing I have heard is that sometimes squeeky brakes will trip the ABS sensors. My brakes are squeeking slightly. Especially when they are cold.

 

Thanks for the replys, guys.

The truck has 43k miles on it, so may be it is time to have the brakes looked at ... Todd, interested to hear what you find out, I am going to take mine in as soon as travel schedule permits and will post once I know more.

 

I just got my disco out of the shop for that exact same thing. (only difference was the lights stayed on continuously). As mike suggested, it was the right front speed sensor. $521 for the repair if not under warranty.

 

Just got the Disco back from the shop - and thankful that it is still under warranty.

Rick, sounds like it was the same problem you had. Just the other side of the car. Replaced the "Driver Front ABS Harness" which from my conversation with the service manager I take to mean the left front wheel sensor.

Thanks everyone for your input. The one good thing to come from this whole incident is 'discovering' this forum.

Later,

Bob
