Hello, folks.

I've got a '96 Bronco XLT w/ the 351 V8. About a year and a half ago, I got a warning light re: ABS failure. A trip to the dealer revealed an error code of 63.

Neither the dealer nor my regular mechanic seemed too keen on doing anything about it, and so I learned to tap my brakes in the winter.

I recently came across another post describing the same problem, and a simple solution described hitting the pump with a hammer. Believe it or not, I tried this, and the ABS light went out. I was actually able to get onto some snow and intentionally lock up the brakes, at which time the ABS kicked in, and the brake pedal "pulsed". It only worked the one time, though.

Earlier today, I tapped the ABS module again, and was again able to get the ABS to work the single time. After that, the ABS light came on, and the brakes simply locked up on snow.

Any suggestions on what the problem is, and how I can correct it. It would appear that I do not need to replace the HCU, either clean or otherwise modify what's already installed.

I know the ABS in these big rigs is a common problem, and am hoping to get some ideas about a quick, easy, or inexpensive fix.

Thanks in advance,

Joe

Get rid of it. It is unnecessary if you don't drive like an idiot. I've never had ABS. My girlfriend's jeep has it and it pisses me off although I suppose it is nice that she gets a small insurance reduction for it.

like i said... abs motor, i'm guessing the dealer said $1400 for the part? is it worth it? junkie or parts truck would be the best place to find it. something about the location and water kills them

yo,
Before buying the HCU, verify it is not other possible causes for code 63;


Damaged pump motor.
Terminal backout in anti-lock brake electronic control module harness connector Pins 17, 29, 37 and 38.
Open or shorted pump motor relay coil.
Open contacts in pump motor relay.
Terminal backout in pump motor 4-way, Pins 1, 2, 3 or 4.
Open Circuit 539 (PK/LB)

see Fig. 41: 4-wheel ABS testing

You can go through almost all steps; @ Step P9 you'll need a multimeter that can read frequency - or go to an automotive electrical repair shop and ask them to measure it.

^this^

I don't have it and don't miss it on my car, but I don't drive that in the snow. If you decide to get rid of the ABS, I'd get an adjustable proportioning valve to hook up to the rear line and adjust your brake bias. Basically it will help keep you from just having the rears lock, which would make the ass end try to come around, and redirects more pressure to the front where the weight is when you're stopping.
