My ABS light dame on last week and I have pulled the following codes:
41,42,45,46,51,52 control valves
65 open or shorted pump relay
67 open motor circuit or shorted BPMV output
A short history - the light came on last fall - right after I had the truck oil sprayed. The light went off after a few days leaving about the half the control valve codes that are now showing. I washed the truck just before the latest recurrence but did not go under the hood or use high pressure so I doubt there’s a connection.
The garage I deal with says it looks like an electrical problem maybe ECM related but they don’t have the OBD1 gear required to do a proper diagnostic. The dreaded words “you’ll have to take it to the dealer for that” were uttered. Anyway I was wondering if anyone had any thoughts, particularly what it’s likely to cost me (in hours) for a dealer diagnostic these days. My guy (bless his heart) didn’t charge me anything for hitting a wall on this. Oh and I really have no problem living without ABS if the alternative means giving my wallet last rites to replace a faulty ECM. Here’s hoping I’m still in the good graces of the car repair gods and the light goes off as magically as it did previously without any expensive intervention required…
