Require Help W/ Abs Defeat.

[JimmyRiggin]

This will be my first post here. Apologies if this information is already present somewhere on this site, as I could not find it after about an hour of searching so I decided to start this thread.

 

VEHICLE: 1996 GMC JIMMY, SLS 4X4 4.3L Vortec.

Basically here is the issue....

 

ABS light is "on" I had the stored codes read by my friend and his expensive scan tool at the local shop, 5 codes came back.

 

At this point I won't bother telling you the codes since I have decided NOT to try and repair the ABS system. My decision is final, deactivate it permanently.

 

According to my repair manual, the control unit for the ABS on 4WAL (4 wheel anti-lock) seems to be called the "Electro-Hydraulic Control Unit (EHCU) which I have already located. I have tried unplugging all of the wires attached to this EHCU and it seems to have no effect on the ABS system.

 

I have been trying to locate the EBCM on the vehicle with no success. The Haynes manual I am using is very vague on this topic for some reason and does not tell me anything useful about the EBCM or the location of the EBCM.

 

So my question is this.... Is the EBCM part of the EHCU? Or is the EBCM located somewhere else?? Will unplugging the EBCM deactivate the ABS system entirly, causing the ABS warning light in the dash to go out and leave me with good old power brakes?

At this point I just want to have my ABS light off, NO ABS, but still have regular brakes. What would be the easiest way to accomlpish this?

 

Thank you for your time and any suggestions.

Unplugging the EBCM will result in the light on the dash always staying on.

Is there anything I can unplug that will result in the ABS light not coming on after I have erased the stored codes?

 

Thanks.

The bulb in the dash. If the system has a fault, it has a fault, unplugging things will hide the source of the code, but will creat a new one by lack of communication with the item unplugged.

What caused the ABS to come on? Did you get bigger tires or gears?

Probably the easiest thing to do would be to pull the gage cluster, locate the bulb and remove it.

if your ABS light is on the system is deactivated. This is a default, if the system detects any issue with any ABS component it disables ABS entirely and lights the light (same with the Air Bag system).

 

therefore, ABS is deactivated already. if you just want the light gone pull the cluster and kill the bulb, simple enough
