Retrieving ABS codes when there is no LED on unit
Moderators: Helpinators, Moderators
Yeah, I tried cleaning the sensor. Afterwards, I back probed the ABS connector while spinning that wheel and got no response. The other wheels give an AC signal when I do that. I do get a circuit resistance around 1 Kohm, which seems to be in family with the other sensor circuit resistances. I pulled a sensor from the junkyard today so I'll see what happens when I swap it in.
I started getting intermittent low resistance readings (~40ohms) on the left rear sensor. The sensor was shorting to the chassis. I could make the short disappear by loosening the speed sensor mounting bolt on the wheel hub assembly. Anyway, I replaced the sensor and everything is functioning normally.
FYI: on ABS-2E systems the L connector is the red wire
