What if it really was a failed EBCM that made them crash? ... then you'd just think they were crappy drivers who are trying to blame it on something else. Infinite do-loop.

Well actually, the NHTSA is concerned if it degrades the braking system the car originally came with. In fact they are concerned if the ABS is affected in any way. When filing the complaint, you are asked if the system, ABS/TCS in this instance, is affected. They will tell you that the part or system in question is degraded thus affecting the overall braking system. In fact, the real point here is:

1.) The potential for an accident is much greater due to loss of ABS/TCS. IN fact if these systems were not indeed safety items, would they be mandatory in the upcoming years, 2008 to be specific?
2.) The fact that this is a known problem and has not been addressed makes it even more of a problem because it is basically turning a blind eye to the problem.
3.) Safety of the driver is jeopardized regardless and that is where the NHTSA gets involved.


What alot of you are neglecting to realize or consider is the fact that many people haven't the foggiest idea what some of these lights mean. We on the forum understand more than most because we are more of the enthusiast type. We read up on this stuff like it is the latest greatest novel or magazine article. But suppose you are just Joe/Suzy who bought the car because it looks nice. You may have no idea what those lights mean. So you drive around and then lose control of your car while braking and kill yourself or some other driver/pedestrian. Could this have been avoided with ABS/TCS? Statistics state that over 40% of the accidents could be avoided if they had ABS or TCS. If the potential exists, then there indeed lies the problem. GM knows there is a problem and refuses to acknowledge and replace the part with a better part just like the case with the infamous column lock bypass.

After having an on going problem of ECBM service light keep coming on and going off. I pulled the 2 fuses for the abs one 40amp and one 20 amp located under hood. 2001 vette. I noticed a brass colored film on the contacts. With a small piece of steel wool I cleaned both sides of the contacts on both fuses and poof problem gone. I wonder why Mr. Goodwrench didn't try that!!! Maybe he wanted the $3200.00 he quoted me to fix it???

I really hate to sound stupid but where do you find the ECMB box in the car. This is my third vett and I don't remember nearly this many issues with my first two, a 75 and a76. Of course I was much younger then. I got a copy of the ground points from an excellent post by Bill, but have been unable to really locate the ECMB box. Any help will certainly be appreciated. Jerry

I was leaving my apartment complex in Sunny California one day to go to work. I was just idling out of the parking lot to the stop sign before I pulled out onto a VERY busy and dangerous street which happens to be across the street from a high school. The stop sign was at the bottom of a small hill, so no need for gas because idling and gravity would get me to the stop sign. I had no brakes at all! My brakes were in good condition and not due for any maintenance. I had my car for almost ten years by this time and I was very aware of the car and all it's requirements. My guardian angel was with me that day because I rolled right out onto the busy street and no one hit me and I didn't hit anyone and thank the Lord that no high school students were walking anywhere near me at the time. I immediately took the next street off the busy road and crashed into some shrubbery to stop my car. I called AAA and my insurance company and had the car towed to my mechanic. He assumed that I meant that my car needed brake work when I told him that I had "no brakes". He didn't understand that I literally had NO BRAKES. He almost hit the wall of his repair shop because it wouldn't stop. He emphatically stated that, "No matter what, your mechanical brakes should have worked, even if the ABS was malfunctioning." He took the fuses out and my mechanical brakes started working again. He took a quick look and let me know right away that the ABS module had fried. He said it was a serious safety issue and to take it to the dealership to have them document the problem and take it from there. I took it to the Bob Stall Chevrolet dealership in La Mesa, California. They verified that the module was fried but they would not comment on the brake situation. They just kept insisting that they couldn't duplicate the problem and the brakes worked fine when the car came in. They kept my car for about two months and then finally told me that the part that I needed was no longer made and they wouldn't be able to repair my car. I'm very thankful that no one was hurt the day that I was driving when the brakes failed. I don't understand how that could happen and neither does anyone else that I talk to, but I do have a witness who drove the car right afterwards and who can attest to the fact that I had no brakes at all. I think it is a serious safety issue and have tried reporting it to NHTSA and to GM. Crickets... I'm just posting it here in case anyone else has had the same situation or has heard of it.

That's a strange failure. The EBTC module had to fail so it energized the master cylinder isolation solenoids while at the same time not energizing other solenoids which could provide alternate fluid paths to the calipers.

EBCM rebuid at ASAP SPEEDO. Just got mine done.....works perfect.....$60 for the rebuild with lifetime garentee.........

Too Slow '90

From what I read the '97-'00 cars have the ones that can't be repaired.

I am in process of replacing second EBCM on my 04. First one was under warranty. It is a fault and a safety issue. Same goes for steering position sensor.

laurent_zo6

It appears that once your warranty period is over, GM's message to you is: "Thanks for your purchase, now drop dead!
There should have been many recalls on the C5 (Steering wheel lock, EBCM, valve springs, fuel tank, etc...) but unfortunately GM will only react when faced with class action lawsuits such as the current ones dealing with drivers' deaths.
A recall does not always fix the problem anyhow. Witness the steering wheel lock fiasco where you have to install a CLB or LMC5 after the recall work has been done.

Unless things have changed over the last few years that I have been out of the C5 community he only repairs one failure in the 2001-2004 models. The failed relay. He can't do anything about 99.99% of the other failures that can occur as he doesn't have access to the repair parts which can only come from a chip supplier to the GM supplier who designed the module. Those parts were probably ruled obsolete by that unknown chip supplier before the last of the 2004 models rolled off the assembly line. Chip suppliers change technology about every two years and if a chip technology doesn't sell well (100s of millions of parts/year) it is declared obsolete and production ceases.

He has another additional thing he can do to keep the relay contacts from wearing so quickly too I believe.

Ok; I removed my ebcm and all I did was retouch the five (5) solder joints with a soldering iron . Some times they have a bad joint, crack in solder or a cold solder break. It worked for me no problems for 2 years now. You can get pics of the 5 places to re-solder right here and its from bill curlee. do a search you have nothing to lose .. takes about an hour or so.... good luck..

ronaldjohnson

mine is out as well where do you send the module?
