ABS INOP light-because of AIR/EGR removal?
My buddy and I have both got headers on our LT1 birds and had all the EGR/AIR systems removed. The check engine light comes on, which is no suprise, but we both had our ABS INOP lights come on as well.
Does this have anything to do with the EGR/AIR removal or is it just a coincidence? Im hoping it goes away with the tune im getting done soon.

I would tend to think that the speed sensor that goes to your front calipers might have rested against one of the headers and burned before attributing the EGR/AIR removal. The wire runs right down the side of the wheel well and is perfectly placed that if your headers are really close to the frame that they'd probably melt.

Am I understanding the post correctly that you installed the headers and removed EGR/AIR at the same time? EGR and AIR have nothing to do with the ABS, but like I said if that speed sensor wire that goes to the front wheel hubs melts then your ABS INOP light will turn on - or it's even possible that it came disconnected as there's a jumper plug that's on the frame on each side of where the headers are.

My buddy's 94 did the same thing when he got his EGR/AIR removed...the brakes in the rear are new this year as of a few months ago, and the front ones where put on last year and I took them apart about 2 weeks ago and looked them over-Everything looks fine.
I still have to look at the driver's side wheel well to try and find that connection.

yea, I couldn't tell you what the deal is. The ABS seems to work fine, but the light is on. It happened after I took out all my EGR/AIR stuff, and it seems to be that im not the only person with this problem. I checked all the wires under the hood, and nothing I can see has been dismantled or burned. I'm hoping it goes away with the tune I'm going to get done this winter when I have the EGR AIR stuff deleted from the tune.
Does anybody else know anything about this?

hahaha the tune wont do anything man to get rid of the ABS light. there is nothing in the PCM anyways that will change that. seems like a coincidence that something got bumped or whatever during the EGR removal.
what it could be? i have no idea. but i do know for sure a tune to delete the AIR/EGR isnt gonna do squate to eliminate the ABS light

It's weird, this happened to my buddy's 94 TA also...and he didnt even have the air pump removed, he just blocked it off on the headers...huh...

ABS is computer controlled, and it should throw codes. Not sure if Auto Zone or someone like that has a code reader, a dealership certainly would, and I know on some cars it's read through the ALDL and there are terminals you can jump, count the flashing lights and you have your code.

Does the light come on and stay on, or is it intermittent? Get the codes pulled. Easy check would be to check fuses. Without knowing the code though it's just a guessing game.
I know you said you don't have light out on the car, but did you get someone to depress the brake pedal and make sure all of the lights brighten?
