Abs /brake light on intermittently, lose speedo at about 50 mph,starts to bounce. rear sensor has been replaced, ebcm has been checked,rear has been scoped to make sure it’s reading the ring gear correctly,shop had it 14 days,charged me a fortune, problem back next dayhas anyone found the correct fix for this problem ?
Has the wiring on the axle to the rear wheel speed sensor been replaced? I have found broken wires on these. Measure the resistance in the wiring to the rear sensor at the ABS module connector, it should be about the same value as the sensor. Have someone wiggle the wiring on the axle while watching the ohm meter.
