Disabling ABS

janorine · Oct 12, 2003

Hi all,
I pick up my new (to me) 96 XJ tomorrow and I'm already planning to swap out its existing Dana 35 for a 29 spline 8.25. however, I think the new rig may have ABS and of course, the 8.25 will not. My question is, how do I properly disable the ABS so as to not have any conflicts with the remainder of the brake and electrical system? Has anybody else out there performed this same swap?

I would also like to hear from people who have done this. I assume that if you simply pull the fuse then the computer will forever complain that the ABS system is faulty. How can the ABS be disabled and/or removed without causing any other problems.

Thanks,
-Brian

That was one of my concerns as well.

Pull the fuse under the dash, this disables the ABS system and the light comes on on the dash. Now pull the ABS pump relay from the powerbank under the hood. This kills the pump and makes the light turn off. No ill side effects with the current generation ABS systems. This is exactly how I disabled the system on my '95 XJ 3 years ago, and I've been running like that ever since with no problems what so ever.

Why?

Why would you want to disable the ABS? I'm being a smartass, but I'm new to this and am asking a real question.

Well, most "aftermarket" axles aren't equipped with ABS, so if you swap in a new axle, as I did, ABS won't work with that axle so the system needs to be disabled (it's a 4-wheel system and you can't just disconnect one half of the rig).

In janorine's case the axle he's swapping in isn't ABS equipped either, so his ABS system needs to be disabled.

Also, the ABS pump takes up a fair amount of room under the hood. Room that could be used for an air compressor or something else, so some folks disable the ABS system in order to take out the pump to free up that room under the hood. I just haven't gotten around to pulling out my pump yet.

I have no diagram of which fuse is which under the dash, do you know which one it is? Can you take a pic, or something? thx!

And then i just pull the huge relay under the hood in the relay box, and im done?

It's listed in the owners' manual and any service manual (ie: Chiltons, Hayes, etc). I don't know which one it is off-hand, but I could look it up tonight if no one posts it before then. The pump relay is marked in the relay bank, you just pull it out.

Speed_racer · Oct 13, 2003

yeah, the ABs one is marked in the bank. but my Haynes does NOT have a layout picture of the fuse block under the dash, nor a description.
it says "view the cover" lmao!! its 10 yrs old, that cover is long gone!

Jeepin Jason · Oct 13, 2003

cover? what cover? My '95 never had a "cover" for the fuse block under the dash... :anon:

Speed_racer · Oct 13, 2003

lol, weird! POS haynes

DO all 96's have ABS?

Stoney · Oct 14, 2003

if u just cut the lines or anything like that the system defaults to normal braking conditions! trust me i did it about a year ago! brakes work bling bling!!

No, ABS was never a standard feature on XJ's.

Dana 44

So if I get my hands on a older Dana 44 that was originally in an XJ I'll have to disconnect ABS as well?

Thanks,

Yeppers, that's my situation. My '95 came with ABS, but it now sports a D44 from an '87 XJ, so the ABS went bye-bye!

Speed_racer · Oct 14, 2003

did ya get the pic for me?

Jeepin Jason · Oct 14, 2003

crap, no I didn't, I'll try to remember to do it tonight, sorry

Speed_racer · Oct 14, 2003
