Well, I have been reading the archives for about 3 hours and am hoping some new experiences have surfaced which match my symptoms.

At first they were on a little bit, then went away. Now, every time I start the engine, they're back. I have replaced the brake switch, and cleaned all four wheel rotation sensors. Some metal at or near the magnetic contacts but no help on my problem. I have also inspected the wiring from the sensors and the brake pad (left front is the only brake pad se

I recently serviced the battery connections and verified I have good grounds at the battery and from the engine to the frame, etc.

I want to know a couple things that might help me. I have a generic OBDII reader but only know of one place to hook it up. Where is the test connection for the ABS/ETS system and should my reader work with it also?

Also, the long travel switch may be suspect. is it one of the two cable operated switches on the brake pedal. One is the shifter lock out for sure.

Should the ABS/ETS pump test run each time the key is turned on?

I don't think my ML has the stability package so no steering angle signal that I know of.

I plan to jack up all 4 wheels and run the Ml in gear to check the signal from each wheel speed sensor. I don't kwow what it should read but if all four are the same I should be able to eliminate that.

I only have one brake pad thickness sensor, left front, is that correct?

Thanks, I think there are a bunch of us driving around with these lights on. I, for one am looking to fix this!
