Hi I've replaced both front wheel hubs in the past yr and the flexible harnesses, i can't get trouble codes off, i scan it and code coo40 keeps coming up, i clear codes with scanner (and then scan again without turning key off and says no codes, i then turn key off for few seconds and turn back on and scan again and code is there again coo40 along with the 3 trouble lights, any ideas how to start testing wires etc? I've checked ohms at sensor was 1095 or so. Not sure exactly what and how to check flexible harness up to controller for possible bad wire?

 

my break light and traction light would not go off. had to replace the brake modular. new one cost 1682.00. could not find a used or rebuilt one to match the part number.It took care of the problem. All the rest of the warning lights stayed on. I tried an old trick, i disconnected battery negative ground. So far all of the lights are working the way they should.
