The ABS light came on and I could feel the ABS through the pedal on even very gentle stops. Fluid is o.k. What could be wrong? I have done some ORM's that were suggested here that should have no bearing on the problem. Thanks in advance for any help, Kenny |

Sounds like an ABS wheel speed sensor is going bad. |

This is what I have so far............ ESP/BAS, Trac, and ABS lights are all on 2006 Jeep Liberty CRD Part number from Chry. 06 Jeep Liberty SPEED SENSOR Rear either side 52129178AC $13.35 Right front side 52128694AF $31.45 Left front side 52128695AF $31.45 Here are a few thing I found in the forum on this. I have the same issue. They say it also could be a possibly clock spring. The clock spring is what the steering wheel angle sensor takes it's measurement from. If the spring is broke, the ECU can't tell when your wheel is turned or going straight. Missing that critical piece of info the ECU disables ABS, ESP and BAS for safety. The Airbag light would be on also and the horn would not work either if the clock spring was broke. They say most scanners will not tell you which speed sensor is bad and most dealers want around $70 to diagnose. The ABS light will reset itself after you drive faster than a certain speed (I think its over 20mph) without an error signal to the ECU. I've replaced three sensors so far (2 rear 1 left front. One came with the new wheel bearing hub when I replaced it. |

This very same issues is common on GM vehicles as the sensor/tone ring gets some corrosion between them making the ABS activate all the time at slow speeds,can be scary.GM even has a recall out for it on some vehicles,a TSB for all others. |
