question and poll regarding abs module

I got my second abs module in the mail today and have a question do i have to replace the whole unit or just the plastic part with the connector? can it be seperated? If so does this mean i dont have to bleed the brakes?

Just trying to get around the 125 price tag mechanics want ( i dont know how to bleed brakes )

thanks

also just curious how many people have had this problem. maby we can get a recall. just seems crazy that this will be the second one i replaced in 4 years. that would have cost me 6,000 if i went to the dealer

Theres a couple of torx screws that will allow you to pull the solenoid assy from the valve body. I would do it that way first. I'm assuming that the coils burn out over time, and the computer senses this.

Bleeding the brakes is easy if you have a helper. I'll give you the info if needed.

so I could just remove the torx screws? should i expect anything to pop out or spring out, fall out, or leak out ( is there any fluid in this part?)i dont want to loose anything and then just screw the new one one with out bleeding the system?

I talked about this once before, guess when Dino, aka Bandit was on the board. So will say it again, so,

insert 2 cents

The ABS module ain't much more then a shuttle valve, and if you don't lock them brakes up and use that shuttle valve, it does nothing but sit there and rust up since brake fluid is a big sponge for water.

When ever it rains or snows, I lock um up and get that valve jump'in and I ain't had any problem at all with my VX or other ABS equip't vehicles. I try and do this at least once a month.

remove 2 cents:bwgy:

Undo the electrical connections, pull the screws, and the coils half can be removed from the valve body.

You can even drive with it off.

John C.

hey, this sounds encouraging, if I don't have to fool with bleeding the brakes then I may try this
First I need to get the ABS module
Thanks for the input on ABS Rowhard, never thought I would consider intentionally engaging the ABS but I guess you're right, weird that I've got my 98 A4 (160k) with ABS and never had an issue and never engaged ABS, if anything, I think I have used ABS once or twice when I got the VX as the thing was so stinking heavy compared to what I had been driving, oh well, it's in need of replacement now regardless....

Ok i got the new abs module and can take off the plastic part but on the one in my car its right up against the fender . I am guessing i cant bend the pipes to get the unit streight so does anyone know of a tool that would get into the tight space to unscrew those star screws?

Ok I finally took of the plastic computer part of the abs pump ( after 3 days of trying to get a tool for the bottom left screw i just said screw it and broke it off) and installed only the plastic computer part - the screw on the bottem , took of the battery termal to reset the code ( not sure if this actually does anything) and after a day of driving NO MORE ABS LIGHT ;party: this way i dont have to bleed the system

So I have a used ABS Module and wanted to do the same thing, remove plastic side and not bleed brakes. How has this worked for you since you did swap.

bleeding the brakes is so easy though.. its a routine scheduled maintenance that should be done every 2 years anyway.. i could easily replace the abs module and bleed all the brakes in under an hour.. or if you dont want to do it yourself, having the brakes bled at a shop should only be like 35-40 bucks imho its worth it to do it or have it done

Brake bleeding is super easy if you get brake bleeders (see Rickshaws gallery). They are easy to install and allow 1 person to do the job easily.

Another way of activating the ABS is off roading. When going down loose rocky/sandy hills with your brakes on you will feel the ABS working!:bwgy:

I replaced my ABS Module last month. It was very easy following etlsport's ABS Module Replacement (How To)
Along with Speed Bleeders, took about an hour to do.

been months now and no problems

What are you guys paying for the replacement module? And where are you getting them? Thanks in advance.

i paid 100 for mine.. found a parted vx and bought it from the owner.. it is also identical to the one found in either a trooper or rodeo with 4 wheel discs, just cant remember which year/model

Hey Frank (swift16),
I got mine here
Mine was from a 2001 4x4 Trooper. Paid around $130. The part number was the exactly the same 8971621921.

Frank, when are we going to do Cars & Coffee

Just got my VX last week and my ABS is going out. Other than not having ABS, is there any other reason to replace the module? Will it cause any damage to other engine parts? I'll probably fix it eventually regardless if I can get one for $130 <-thats a good deal.

Hi jon.

No,it cause no issue to the engine or drive train.

I think many members just get the ABS off drive without it

Okay, thats what I thought. I will let it stay broken for the time being. Thanks :yeso:

yep, i drove around without my ABS for over a year, even passed MD inspection with it broken

Anyone remember Torx size on ABS side plastic piece neede to just remove the half?

Cannot get torx out due to limited space to just replace electrical side any suggestions

iirc the only way anyone was able to remove the electrical side of it without removing it from the VX was to break the bottom mounting tabs off.. seriously.. its easier to just replace the whole thing and bleed the brakes

I am sure I will get flamed for this, but I know there are some other VXers that run with the ABS fuse pulled. ABS is not really needed. Mine only activated when I am wheeling and brake on a loose surface, just feather the brakes, problem goes away. I am not a big fan of ABS in general. Mine currently works, but if it fails, that fuse goes bye bye.

I have heard a lot of people say that they don't need ABS.

I would like to relate my experience -

A few years ago my son and I attended an Advance Sport driving day.
The day was held at a race track, 8 students, 4 small Alfa Romeos, 4 x experienced racing car drivers as instructors.
We were taught all types of braking techniques including ABS, cadance braking, feathering, and hand brake use for turns etc.
The Alfa's were set up with a dashboard switch that turned on / off the ABS.
A section of track was wet down and we all tried emergency stops from 50MPH with different techniques we had been taught. After trying in the Alfa's, we also tried in our own cars.

No one, including the race car drivers, could stop in less distance without ABS, as they could with ABS.
The different techniques we had learnt certainly made a difference, but the closest anyone got to an ABS stop (without using ABS) was about 2 car lengths.
By all means, drive your vehicle without ABS if you want to, but don't think you can stop as quick. It just ain't gonna happen.

Just thought it worth mentioning.

Of course Marlin doesn't need to stop any more, he can just crash right through.:bgwo::bgwb::bwgy:

I agree Marlin, but what benefit is there to pull the fuse? The light will remain on with fuse pulled wont it? I didnt have ABS in the other VX and I dont in the current VX, just want to get the light to go off so inspection is not an issue.

Lisa, it's so easy and just takes a few minutes to do-

Open hood, remove ABS module connector, bend over the #16 pin, replace connector, close hood. Two to three minutes tops.

Say goodbye to ABS forever. :) :_beer:

Thank you!! I too have no intention of fixing it whatever IT is.....

Even though I have the parts to fix my ABS I wont. I have had several extremely close calls when it was working. Slammed down on the brakes and it just kept on going and going, stopping just inches from the car in front of me.

Since it stopped working I have never had a close call... my stops have been quicker and in control. Maybe that is just my experience but I would never restore the ABS function while I posess my truck.

Anita, I agree 100%. That is the worst feeling when you hit the brakes and keep going 'cuz the ABS won't let you stop. Lots of other 'Zu owners over at the Planet have the same complaints. This Isuzu ABS system is too sensitive! If you think it's bad on pavement, try it on snow sometime. Holy crap! Very scary stuff.

All the new VX owners should test their ABS on a couple surfaces to see how sensitive it is on their VX so they don't get a big surprise when they need to stop quick. If I buy another ABS vehicle, I'll check it out right away and if it's too sensitive it'll get disabled immediately. Word.

i like that

so you pull the fuze and the light goes away....what fuze is it.

Just wanna share a light

Dave from shelton in CT told me he had his ABS pump swapped with a 2001 trooper equiped with the TOD system.

It's an direct fit;only cost him $ 130 from salvage yard.

hello this is david from shelton ct i have had this pump in for 3 days now and i have tried to abuse it and there has been no problems at all .

On smooth wet pavement ABS might help but on a bumpy road I bet I could stop at least 50 car lengths shorter now that my abs has gone out. I LOVE my truck twice as much since the light came on! With all the snow now and my new Coopers I just slam on the brakes and slide to quick silent graceful stop every time. No more clattering and shuttering and grinding vibration. So peaceful and reassuring to just have the truck freaking stop when you press down on the pedal. I've almost had a crash at least three times when I slammed on the brakes on bad pavement (always seems to occur where everyone slams on their brakes) and the ABS decided that it was better to keep the wheels spinning than let them lock up. And around here there's more bad pavement than good. I LOVE having no ABS!!!

I finally did get sick of looking at that ABS light though and so I bent the pin like it shows in this thread http://www.vehicross.info/forums/showthread.php?t=12016 and it's still on. Then I pulled the fuse and it's still on! Then I replaced the fuse and unhooked the battery for a minute and it's still on!!! What am I missing??? How do I shut off the dash light!

i just took all that crap off i hate ABS when offroad some time you need to be able to jack the brakes and slide a little

I wish I could just figure out how to turn off my ABS light. It's getting old.

Do a search, someone posted which terminal to bend off of the ABS relay to make the light go off

Ooops my bad, I see where you tried that and it didnt work.....

When we went wheeling at Uhwarrie all the Zu owners pull the fuse so the ABS is cut-out during the tough trail negotiations...
