Have you changed the tail light stoplight assembly? There is a voltage sensor in the system that can show this problem if there is not the correct current being sensed when the brake light is activated. Some of the earlier LED replacement units had to have resistors added to correct this problem.grabyfam said:Did you solve your problem? I have an 03 GT that I am having an ABS problem on and have checked about everything even took it to the dealer and had them diagnose the ABS. They cleared the codes but the light still came on when they were there. The symptom is this, I can drive the bike out of the driveway and repeatable apply the brakes and they are OK. Then in about a 1/2 mile the light comes on after I apply the brakes. Then once it comes on it doesn't reset. Does anybody have this symptom or had this type of problem fixed? The dealer said that it was a wiring problem and said who knows if they could figure it out. So what I am looking for is suggestions on what other people have found that could be wrong. And what they have had there dealers find wrong. I really want my ABS to work again. I have inspected as best that I can and currently have my bike completely torn down of all fairings. Please HELP!!! I am a mechanic and to the best of my abilities have not solved this problem on my own and don't want to have the dealer take me for hundreds of dollars.
Boy tell me about it. My ABS lights wouldn't reset and the BMW "mechanic" diagnosed a faulty computer. The part lists at $2800.00 + Cdn and is supposed to take 9 hours (at $90/hr) so with taxes I was looking at getting pocket change out of $4000.00Bobmws said:...It sounds like you may need to locate a dealer with a competent electrician. Many good mechanics are not well versed in dealing with electrical problems.
Check the sensor gap with the feeler gauges in the tool kit first. The sensor may have moved because of the low side. Make sure to check the gap in more than one spot by taking a reading, then rotate the wheel and check again in another spot. There can be tight and loose spots.Richinga said:I low sided my bike a few weeks ago at a relatively low speed.
