    Default abs question



    I recently had a ford 8.25 rear axle put in my 2000 xj. The abs light is on, and I assume it is because the wiring haness for the jeep, and ford axle do not match. Does anyone know how to eliminate the light, or join the 2 harnesses together.

    I have read about guys removing the fuse for the ABS.

    Do you want ABS to function as intended?

    I assume only the rear axle / brakes changed, yes? Are the "new" brake assemblies ABS capable?

    First off do they both have the same exciter rings. On the carrier?

    If they do match it should be an easy swap it's only a 2-wire system you're going to be right or wrong.

    Edit: do you mean Chrysler 8.25, or Ford 8.8?

    Not sure about the 8.25, but the Ford 8.8 has the tone ring on the carrier, not on the individual axle. There are exactly twice as many teeth on the 8.8 tone ring as the jeep axle, so you can grind off every other tooth and wire the two sensors together and plug into the ford sensor.

    You have to have the exact same amount of teeth per revolution on the front wheels as the back otherwise the abs freaks out and starts pulsing.

    On mine I removed all of the sensors and the sensor wires, and I pulled the bulb and relay for abs unit. Pulling the relay, the bulb stays on because it was powered from the ECU not the unit itself. Not sure if emissions will fail the vehicle if the ABS light is on.

    I removed all the ABS stuff out of my Jeep and have the light on constant now. It does not fail emissions due to the light.

    That is good to know. They were giving me all kinds of crap when I took my jeep in because they had to do the special computer only test because my tires were too big for the machine.

    My ABS is run through a fuse. So when I hit the trail I just pull the fuse.

    I tryed tuning Chinamans with ABS and it was almost undrivable
