02 ML320 BAS/ESP/ETS/ABS Lights
I know here we go again another post about the 3 famous lights on. I've read a number of posts already dealing with the issue and potential problems and things to look for . I've already done many of the recommendations that are just check this and check that but now I guess I'm at the point where I need to start spending money so I'd appreciate any help on where to start. Here is the problem which by the way is intermittant. Sometimes while driving and going around a turn I'll get the pulsation in the brake pedal like the ABS is applying the brake to one (or possibly more ) wheel(s). This will not produce any lights on the dash. At other times when I try to accelerate like maybe off of a stop or merging into traffic I get the hesitation or loss of power accompanied by the 3 lights on the dash. Things I have already done with no success: replaced the ABS relay , Inspected te plug on the ABS module for corrosion (none), Verfied the ABS pump runs by jumpering terminals in the relay socket, Reset the Steering Angle sensor, Inspected/cleaned the wheel speed sensors (no noticible damage or chafing to the wires but I didn't start peeling back the eletrical tape like I read one of the posts on here said), Pulled the low range motor on the transfer case and got it to work (It was inoperable and I was having the low range light too ) and replaced the brake light switch, Put a standard OBDII scanner on it but it didn't have anything to offer.
So there I think I tried all of the "don't cost much to try" stuff . Any suggestions on where to go from here??
