NotEnoughGPs Posted January 17, 2018 Report Share Posted January 17, 2018 2003 Grand Prix. 187,000 miles. New Moog wheel bearings. Both the ABS and low traction lights are on. As experienced in other GP's, the ABS wiring is broken or badly corroded. I tried to remove the wiring from some junkyard GP's, and noticed that the wires are very thin. Are they 18 or 20 gauge? Has anyone tried to run new wires from the ECBM to the connector on the wheel bearing for the front wheels? Quote Link to comment Share on other sites More sharing options...
runt Posted January 17, 2018 Report Share Posted January 17, 2018 They sell pre-made replacement harnesses which I'd recommend over trying to replace an individual wire. I think I had about $60 into both sides when I did my '07. NotEnoughGPs 1 Quote Link to comment Share on other sites More sharing options...
NotEnoughGPs Posted January 18, 2018 Author Report Share Posted January 18, 2018 Ok. I see that Rockauto sells the replacement ABS harness. I will get one of them as I have read that trying to solder any 18 gauge or 20 gauge wires to the stock wire connector on the ABS sensor on the wheel bearing itself is going to be impossible as the wire itself can be so corroded, it actually disintegrates. I also have been advised to get the ABS system scanned as there may be more of a problem than just a broken wire going to one of the ABS sensors.

rich_e777 Posted January 18, 2018 Report Share Posted January 18, 2018 I had a broken ABS harness on my old GTP but I just soldered the wires back together and taped them up in splitloom. Fixed it for me and I didnt have to replace the hub bearing. Imp558 and NotEnoughGPs 2 Quote Link to comment Share on other sites More sharing options...
Imp558 Posted January 18, 2018 Report Share Posted January 18, 2018 When a wire is badly oxidized you just cut it back to a clean spot. When there's mild oxidation either use acid core solder or simply fan the strands out and drag a razor knife backwards on them to clean them up before solder. For the less faint of heart it's even possible to extract the pins and solder a wire right back onto it to replace it all.

MiriV Posted January 19, 2018 Report Share Posted January 19, 2018 I also have been advised to get the ABS system scanned You should, the ABS module itself is prone to going bad. Quote Link to comment Share on other sites More sharing options...
