ABS problem

Guys,


My 1998 Grand Cherokee is illuminating the ABS light all the time now. Was doing that from time to time and we swapped in a used controller as our state requires that the ABS work to pass inspection. Fixed it for a while.


Replacing that part is a PITA! And new controllers are absurdly expensive!!!


Is there a chance we have a bad hall effect sensor rather than a controller problem?


THank you



Mike

If your state requires functioning ABS (lol, wtf?) then I think you'd best invest in a scanner that can pull the ABS codes. DRB3 is the factory tool, snap on MT2500 should do it, some newer options can but it's hit or miss.

It's totally possible you have a bad sensor, connector, etc, but the only thing that can tell you that is the jeep.

It’s really not that hard to replace the abs controller if you realize that you don’t have to break into any of the hydraulics. Maybe this will help:

I bought a rebuilt unit, and it worked great right up until the last day I had the Jeep. Too bad I didn’t remove the controller before I donated the Jeep. Do a search on the forum. There are a ton of posts on this hm readings for the sensors, etc.

this is the part that gets me... generally if ABS isn't working the brakes would function as they would if the vehicle just didn't have ABS to begin with and i guarantee they make exceptions for such vehicles

so glad i'm not in an inspection state... of course there is always the "find a shop that will just give you the sticker" method... i've seen cars from inspection states with up to date stickers that make me wonder how it passed
