ABS LIGHT

[scubscout53]

When I bought my 96 Bronco four years ago the ABS light was on with a piece of black tape over it. I wasn’t concerned as it drove great. Figured I’d work on it down the road. After reading some posts on this site I’m wondering if I’m better off leaving it. I bought it from a long time Ford salesman in Alabama and he took very good care of the truck so I’m wondering if he might have experienced the issues others have mentioned. I don’t drive this truck very much and just put all new Goodrich all terrain tires on it. Thoughts?

Yo scubscout53,
Here is the reason for the tape;
4WABS Control Module Bypass for PSOM Operation due to a Bad 4WABS Control Module at 4WABS Module Connector; "...jumper 14 (CKT 530, LG/Y)to 21 (CKT 519 (LG/BK) & 39 (CKT 491 (O/LB)to 22 (CKT 523, R/PK)..."

It's electric motor was bench tested first to ensure function; the old one was tested too and it has an open circuit. But the ABS light is still on so chasing down codes 41/42 front brake sensors and code 65 Acceleration Sensor. Did not get a code 11 (Control Module) even though these are known to go bad if the HCU fails. Fun and games!"

Confession time

I was running some nice big 35" BFG mudterrains on the back of the Bronco. The front just had stock. If some one would **** me off i would stomp on the brakes .... nothing gets someone's attention like the sound of big nasty tires roaring to a stop. It would literial have people ******* them selves.

My freaking ABS light comes on and off.

It just so happens that it was on when some punk pulled out in front of me. I thought I would let them roar a little for him. Well....... the next thing I know I'm doing a 360 in the middle of the 4 lane. This time i almost ****** myself.

When the light is on ... it doesn't affect anything while normal breaking. When you have to slam on the breaks ..... crazy thing will happen. just be aware.

It seems, correct me if I'm wrong, that we're jumping ahead with no codes recorded yet...
