What happens if you dont fix it?? Ive been having the same problem for the past month. Some days she agrees others not so much.

 

Your ABS and TC won't work-much easier to lose control of the car when you least expect it.

 

Before you do anything drastic, check your front tire pressure on both sides and make sure they're identical.

 

??????? might i ask why ?

 

I over inflated one of my tires on my 02Z. I was using one of those gas station air pumps and the gauge was garbage just like all the others... Doing this set the tire height different from the other tire. The computer measures the speed at which each tire spins to figure out if they're both turned straight, left or right. It measures that against the steering wheel position. If they don't equal the same, the AH doesn't know which is right and shuts down the AH and ABS.

So my since my tire pressure was different, at different temperatures my tire was taller than the other. That set the system off and turned off the AH/ABS. It took me a while to figure this out. But once the tire pressures were equal in both tires, this problem went away.

The AH/ABS turned off on my almost every single time I drove the car. On colder nights it'd take just a little longer to happen, but it would eventually happen.

 

Mine has been coming on in the morning just pulling the car out of the garage. Sometimes in the afternoon when I leave work, I turn on the car and a few seconds later the ABS and Traction Control lights come on. So I don't think mine is a tire pressure problem.

 

Gonna send mine off as well, I have the same problem. 02' z

 

DO NOT GO TO THE DEALER!!!

I just had the EBCM module fixed. Sent it off to ABSFixer. You will save some cash for other upgrades.

 

There's a company on the auction site that's fixing them for $50 bucks. The companies name is ATE.

 

Thats what mine is doing. If I can go 2 minutes without it coming on, Im good.

 

I have a 98 corvette that has the same type of problem. My code is C1277 on the DIC and sometimes the Active Handling light comes on and sometimes it doesn't. I'm wondering if rain or moisture effects it because it came on the other day after driving in the rain for a bit. But then yesterday it came on again when it was dry. If it's broken how does it fix itself for a few days and then decide to crap out again.

 

Good question Marcanthonystorm, I thought moisture or cold days had something to do with it. Ok, I have a stupid question, how do you read the codes??

 

If you change your tire sizes front and back and they changed differently, will this turn the ah/abs light on?

 

I have a 2003, and had the same message. Additionally, it said do not drive over 80MPH. I took it to the dealer and they told me that I neede to replace the ride module.

The ride module cost about $1,000.00 at the delaership. Ebay has them for about $200.00.

The module is located in the rear, driver side, sitting behind the carpeting liner. it is a big silver thing with heat fins on it. it looks like a big radio amp. Disconect the 2 plugs and replace.


That worked for me.

 

this is an interesting thread i had the same problem with my 01 about a month ago it came on i freaked out so i took it to the dealer they told me the same thing its the ebcm and its about a grand to fix but that was the only time it came on my vette is my 3rd car and doesnt get driven much so if it really is the ebcm it will just sit while i get that part shipped out to get fixed

 

Ok... here is a question and my flame suit is on.. Some may think Im crazy but.. Here goes.. I have a 98, 18,500 -+ miles on it. I plan to keep this car quite a long time. Since everything is working as it should and being that I have such low miles (knock on wood), would I benefit by disconnecting the "discontinued non serviceable non rebuild able" ABS module and just drive as I have no ABS? None of my other Corvettes ever had ABS and i never died.. This way, should I ever sell the car, I reinstall the module and I will have a known GOOD unit. Everyone keeps saying its OK to drive with a DEFECTIVE unit so why not take the known good one out and put it on the shelf? Yeah, I know some of you may be thinking, is this guy crazy?... Well, no.. I'm one of the few that owns a Vette and drives it like it was my Lincoln Mkz. I don't race, I rarely go over the speed limit. I just "cruise". I assume Ill get a DIC error, but if it means saving a non replaceable part that could be needed at a much later date (after Im dead and my kids own the car), I think it is a logical idea.. Any thoughts on this? Really, Im serious.. ABS, Active handling? I've never even pushed the button on the center console. Like I said... I just cruise every now and then. Sorry if this seems like a thread hijack, but I think others may have thought the same thing..

 

You'll have the Warnings on the dask ALL THE TIME and I'm guessing if the other 1/2 of the system (where the EBCM plugs in) does not get exercized every so often it will also die.

 

Located same place for a Z?

 

All these posts and only 1 post that actually listed a code. You guys with the problems should learn how to pull the codes on your car (see the sticky). Pulling the codes is a great tool for a C5. When I first bought my car, I had warning lights for ABS/TC, learned to pull the code, it turned out to be a front wiring harness ...the code told me exactly what wheel. Learn your codes.

Two things; first you will lose magnasteer function. The EBCM controls steering effort and when removed or inoperative the system reverts to straight hydraulic operation. The car will feel like you have lost power steering at low speeds. It is perfectly drivable just more steering effort required.

Second, there is no guarantee that putting your EBCM on a shelf will ensure it's still working 5,10 or more years from now. If you do a search on here you will find posts about cars with anywhere from 15,000 miles to over 100,000 miles having the problem. It's a crap shoot. Also, having the BPMV sit idle for years can't be good for it and you cannot drive the car without it unless you do some serious brake plumbing.
