Probably somewhat true but unless BOSCH holds the patent on these, I don't see where any company would be exposed to any liability that GM itself wasn't exposed to. I mean ABSfixer takes the same chance by rebuilding them.
whether bosch holds a patent has nothing to do with the liability a third party making a replacement would potentially have.
If someone makes a replacement EBCM, it's on the manufacturere to make it work correctly, and if it fails, they could potentially be open to liability.

As an ex vehicle design engineer, you are dead right. No small company in their right mind would try to produce an EBCM. One accident that lawyers (good ethical people that they are...) could tie to the replacement EBCM and you would be out of business at best. In jail at worst.
And yet a case cant be made for not keeping a needed safety device available? Would think a case could be made" I could have stopped but my ABS is inactive and GM wont sell a replacement part". Can work it both ways I would think.

hey now... there are some good people that are lawyers... some of them on this forum.. maybve one or two in this thread :-)

you mean you knew your EBCM wouldn't stop, and you drove it despite knowing that?
The brakes still work, you just lose antilock. Seems in your hypo it's your fault for driving a car you knew didn't have antilock, and not being better prepared to handle it.
The pre-2001 EBCM were made by Bosh, The reason they have not made a production run is GM has not placed an order for them. SEMA has a newer testing facility near the Bosh US headquarters and has been able to have several items made from them and other OEM's on specialty runs for different car makes. However, the C5 Corvette EBCM was not used on other cars although a few GM models were thought to be using it. Last winter I went on CF and other forums to find out is any other cars used that module and did not receive one usable answer. Some suggested a Buick or Cadiillac used it but never a year(s) or specific module. If we could get an accurate and verifiable count I could go to SEMA and see if they could influence a production run.
Lots of discussion that has likely appeared in the many many past threads on this EBCM topic. Has anyone noticed that the OP has not commented since his/her original 11/24 thread starter?
Yellow, if you were so inclined you could MAKE a replacement visor. How perfect it would be depends on how much time and effort you want to put into it.
In the case of computer parts, you can't. Right now it is a practical impossibility to make old computer chips. The equipment is too expensive and companies often have not released the relevant information (drawings and computer code).
If Bosch/GM would release the information (board layout and any needed computer code) it might be possible to repair a malfunctioning board with modern components. People have done that for old boards in other industries.
We would still have to figure out how to dissolve the encapsulant without destroying the rest of the components.
GM may not even have the original blueprints/schematics to produce the part. When the C5 was engineered and built, downsizing and outsourcing (aka; GREED) were extremely popular. I'm not saying they aren't popular still, but some companies are realizing contractors and contract companies/vendors don't always have the same dedication (Linimar?) as in-house employees. When GM decided on Bosch, Bosch may have insisted their technology was proprietary, and refused to release any drawings. Bosch has said publicly (info is out there) they will never manufacture the EBCM again. Market size is also important. Since probably no more than maybe 20% of the C5s (that is probably considerably more than actual) have experienced a failure, and many of those may be in the scrap yard, I have a feeling the market for an EBCM for a 20-27 year old car is very finite. My opinion......

Thanks. You've said exactly what I was trying to express....

This, ultimatly, is the real issue.
There are several off-the-shelf chips, caps, and I believe vrm that are super easy to replace. The issue is that on pre '01, it's all dipped in an encapsulant, and no one has figured out how to dissolve all of that without destroying the board.
IT's also why '01 and newer can be fixed *in some instances*. it's not dipped in encapsulant (or not all of it is coated) If the issue is a broken trace, a dead cap, or something similar, it can be fixed. But if for some reason the eprom is dead, the post '01 is just as unfixable as the pre '01.
But again, it's been said many many times, ebcm issues are few and far between. it's a far overstated issue.

GM Parts Direct listing says only used on 98, 99, 2000 Corvettes. Same for the version without active handling. Looking at Chevrolet's website directly, and Napa, Advance Auto, Autozone, and Oreilly I don't see the module at all. Even Rock Auto doesn't list it, the closest they have is the 97 version.

What do you want a count of?
Can you ask them what the minimum order and price per unit is? At least we would have an idea of how much money it's going to take.
What year and model cars used the same EBCM example would be 1998 Cadillac Seville, 1999 Buick LaSabre, etc ( those were not actual models that had the same EBCM but an exmple of the data we would need)

I have been through 3 in 45k miles. Tell me about "few and far between"?

you've had a string of bad luck. The fact is that it's a rare occurance. Sadly it hit you three times. which sucks, but doesn't change the fact that it doesn't fail that often.

I bought a few of these back in the day and have them sitting on a shelf -- best bet is to find a racing outfit that's running c5's ... they're not as prolific these days as they used to be, but even a one off racer that's serious typically they'll rip out the EBCM and put in a racing unit. I got several for a few hundred each.
I believe part of the problem is many, and I'll go so far as to say most, don't brake hard enough, or drive on slippery roads often enough (winter stored cars) to activate the antilock feature. This may lead to the pump freezing up. Like many things electrical and mechanical, if you dont use it, you may lose it.......

the main reason I bought a Tech2, to do the autobleed on the brake system, did my 99 every 10,000 miles. drove it 70,k with no issues ??

I have not commented because I don't know what to say.
My auto mechanic removed the EBCM and tells me it was burnt (he took it apart). I was not there, so i can't verify. Have been pursuing the used part route. People are generally looking for $2500 or more. On a couple of attempts at actually buying a used EBCM, they have also been burned out. People have been putting these up for sale in unusable condition.

Good point. Although I don't do it on a regular basis, I do exercise my 2001 EBCM at least once a year, in a large, grassy plot of land that's near where I live. Even so, however, my unit still went bad, a couple of years ago. Fortunately, 'absfixer' was able to repair it.......
