Exclamation The Dreaded ABS INOP light!!!

DON'T BEAT ME TO DEATH I AM NEW TO THE FBODY AND THE FORUM
I have long battled the ABS INOP light in my 97 firebird formula. Sometimes i would start it and the light would be on, other times it would be off. Sometimes it could be reset by turning the car off and then back on, sometimes not. Sometimes it would be just the ABS INOP light, but sometimes the "brake" and "low trac" lights would be blinking rapidly to a steady burning "abs inop." So what could the problem be considering i had it to three different dealerships for a total of five times and i left disappointed everytime? I was told everything from the rear reluctor ring/sensor, to the $975 ABS pump and module to the front hub sensors. they made these assumptions with the techII not being able to communicate with my ABS module, which was an odd symptom because it could not communicate whether the ABS INOP light was on or off. So with a little pull and play with the fuses and relays i found it to be a relay. The ABS relay (White with ABS IV markings). So after months of heartache the problem was solved by me buying a generic relay (not the $34.99 relay the dealer tried to sell me) that is the same one that you can pick up at any autozone for $4 that is commonly used with your foglight wiring harnesses. If you pay enough attention the wiring schematics and input load and passthrough loads are all the same as the OEM relay thats much more expensive. It was like magic, when i had my buddy hook his techII up he suddenly could communicate with the module. Wow and the dealership was willing to charge me almost a $1000 for an abs pump b/c from what they say "the install is not possible without the techII to bleed the valvebody." $4 vs. $1000...i would take $4. Just thought i would save hopefully a person or two the trouble.

Thanks for the info. Although, if mine ever fails I'll probably just get rid of the ABS since I never seem to use it. If a $4 relay will fix it I'll do that but if the expensive parts go the ABS delete kits are really cheap.

If the ABS engages it's because you hit the brakes to hard, most likely out of an extreme reflex action in an emergency situation.

The only time I ever had it engage in my firebird was when I drove it in the snow. ABS works well in rain, the rear wheels in my truck use it alot in heavy rain if I'm playing. Whenever I had it kick in in the snow it seemed like it took much longer to stop than if I had gone easy on the brakes and kept them for the point of locking up. Since my car only sees dry pavement and occasional wet pavement, it never kicks in. 315 wide tres help, too.

True, but the abs can come in very handy at times. I was really trying to say why would you want to get rid of it. Most of them can pump the brakes around 10 times per second, most people can barely pump it more than twice. And wouldnt you want to have brakes us in emergencies

You may have just solved the last of my Dashboard lights. Where is that little sucker up behind the fuse panel?

I was just gonna let it be, as I don't use the abs here.

Good timing. Need to replace the turn signal relay as well.

the relay is actually located under the hood in the relay/power distribution box that is located on the DS in very close relation to the ABS pump. That is my car though, not sure what you have so i cant tell you.

2004 Jaguar x-type. JL audio 12's and Sony 900 Watt RMS Amp. Other than that, stock down to the air filter. Will probably stay that way since i bought a dirtbike instead.
