 Subject: HELP: ABS and BRAKE warning lights on!!?
IP: Logged
Message:
I read the post a little ways down about the ABS/BRAKE dummy lights on and the speedo not responding. My ABS/BRAKE lights just started coming on last night, but my speedo works fine. Could this be the speedo sensor mentioned in the other post too? Or should I look for something else? Could it simply be the brake pads (rear shoes were getting down there last time I checked, ~6 months ago)? The lights come on while I'm driving and not using the brakes. Thanks in advance!! Oh, I have an '02 quad cab, AWD/4WD, 4.7, disks(f) & drums(r).

There is a thing called a "tone ring" at each wheel that is included in the ABS system. A sensor reads the grooved wheel as it's spinning. A lot of the time what happens is you may have just spun a tire and it come on. I see it happen every day. Reset the PCM by taking the positive terminal off the battery and cycle the ignition switch 3 times. This most of the time does the trick if it's nothing wrong.

Chris, the lights are not on each time I start the truck. They come on a short time after I get over 35~40mph. Is this the same behavior you see when it's just the tires spinning?
Also, should I be cycling the ignition 3 times with the battery disconnected, or after I've disconnected for a while and then re-connected?
Thanks!

No, if it was set off by spinning the tires and "fooling" the ABS system into thinking there was a wheel that was locking up, it more than likely would stay on all the time. As for question #2, do it while the battery is disconnected. This drains whatever current is left in the ECU so that the computer is reset when you put the cables back on the battery.

Look at your other post, the post by Lurkin gives symptoms of a bad clock spring, see if you have those symptoms.
