abs removal
Tuesday, June 15, 2010 7:42 PM
i've seen threads where the abs module/master cylinder had been replaced with a non abs master cylinder & block, but it leaves the brake lights on in the dash. So I was wondering if resistors could be used to fool the ecu into thinking the abs module is still there, kinda like when you remove an airbag.

why do you need this?
it will still pass inspection, and will not cause any problems
just use black electrical tape and cover the light!

Wait for about 100K more miles until ABS dies. Then you can do sweet burnouts without pulling the e-brake yo!!

um... ive heard rumors that the gm 'tec II' can turn those lights off but idk if its true or not...



180hp in 1989 or 145hp in 2002, you decide. >

step1- pull cluster
step 2-
u have some options here.
A- pull bulb with plyers
B- apply tape behind cluster face.

The Tech II can infact turn off the ABS in a 00+ J car. Never tried in my 98 though. Turned it off on my 02 the day before going to a road course. High speed+Azenis+rain+no ABS=very controlled breaking. Never knew that the rear drums in a J car could get up to 350* untill that day. I guess adjusting them two days before was a damn good idea.

Well, maybe you should get rid of the rear drum, especially, if your taking the car to a road course.
You should put some Subaru STI rear disk on it.
Im not too sure who has done that before?!

It was a "high performance drivers education course" and I have no desire to "upgrade" my brakes. I didnt need any more stoping ability than what was available. I know that at least one of teh big brake upgrades for our cars was shown to increase stopping distance.

I'm curious to know which brake kit that would be.
And Phil, not everyone has the facilities to do what you do unfortunately.
Nor can everybody afford such a setup too.

That was Baer. They actually stated that our factory brakes were very good for our cars.

Wow, that is surprizing. Makes the NRD swap look really good then, cause that swap without a doubt cuts stopping distance by quite a bit. Never gauged it, but I can in the future. Interesting.

To answer the original question: Not using resistors.. no.

How the bulbs are controlled depends on the year of the car.. 95-99, it's driven by UART serial data from the EBCM (Electronic Brake Control Module). On 2000+ it's driven by Class 2 serial data from the BCM (Body Control Module). With either one, you'd have to open up the cluster to mess around with the output from the microprocessor inside the cluster to cut out the ABS light... or just break the bulb...

I'm working on this right now, I've got a few ideas that I'll be trying pretty soon here.

I can give 3 reasons. The brake light also comes on when your brake fluid is low, the brake light also signals your ebrake is on, and in NYS a brake light makes you fail inspection. I could care less about the e brake but I would like to retain the use of the low level sensor.

I just found this out today from talking to my local GM mechanics. Any idea where the EBCM is? It might be as simple as cutting a wire...

that's the reason I asked the question. I want to keep my brake light funtional when the abs unit is gone. I want to remove abs because 2 master cylinders have leaked on the 96 cavi. Only the dealer can reset it when it's removed so alot of $ for a recurring prob. Plus the abs design sucks.

no idea where EBCM is . . . but updates on this please!

The EBCM is under the dash on the driver's side of the car, on the A-pillar, on a 95-99 J-car. Exact same spot where the BCM would be on a 00-05 car.

There's usually a sticker that says "ABS" on the front of it. Two connectors to it.. one with thick wires (feeds to the master cylinder under the hood) the other with all the wheel sensor wires feeding into it.

Thanks for the info Lenko.

I just found a solution, but I'm going to keep it in the main ABS Delete thread. Here's the link...

Well, your 3 reasons is an "EPIC FAIL" !!!!!
You will NOT fail inspection in NYS.
The "brake" light comes on for the e-brake, not the "ABS" light ..... those are two different lights.
And the "brake" light come on for low fluid, not the "ABS" light.

But I replaced my MC, with a 1.375 bore, so I do not have the level switch anyways!

I misunderstood what light you were talking about, I was talking about the brake light the whole time not the ABS light.

A brake light will fail you in NYS, but you are right, an ABS light will not.
