Hi I was wondering if anyone could help with a abs light on a 2005 jeep liberty crd limited, with 248k + on the clock.
This has been going on for a few months. So far I have replaced the abs pigtail, the rear diff sensor, then I found a 02 wiring harness and swapped that in. That fixed it for 2 tanks of fuel.Coming home from work today it popped back on.
I still have speedometer and cruise, but no odometer.

Could it possibly be one of the front sensors? My right front sensor went bad and that stopped the odometer. I don't know if the sensors could fail intermittently (maybe loose connection?).

There is a dealer procedure to bleed the ABS unit. Usually only an issue if you have had your fluid changed or some other procedure that may have introduced air into the system. I had it done when I was having issues. my issue was a broken wire in the harness that goes to the rear diff.

The price, about $80 is the same as a full brake fluid change and includes the bleeding.

I tried to replace the right front sensor and it broke off. I drill out the remains and inserted the new sensor, no help. Could be trashed from the drilling so I ordered a new wheel bearing with the sensor installed. Maybe that will do it?

New wheel bearing with sensor did not help. Now going to change left front?
