have you checked the wiring from the sensor all the way to the module ?

and no 12 and 14 are way different , the 14 module is a 1 year only part # , and shared with the 14 SS sedan

11-13 are a front and rear system , and the 14-17's are a cross system , 1 front and 1 rear are on the same master cylinder circuit

Has anyone figured this out? I'm having the same problem. I've replaced both rear wheel speed sensors and 1 hub bearing (that I don't think was bad). The problem started out as abs light on intermittently but now is constant. I suspect its a wiring problem but I haven't traced the wires from the back to the abs module. I was hoping someone had repaired this already and could tell me where the problem in the wiring most likely is.
