Default 1997 - 2000 ECBM Repair

As an owner of a really clean stock 1999 Corvette that I really enjoying driving every day and having concerns about having EBCM issues, I spoke with Tyler at Module Master / Circuit Solutions

208.892.0764
www.modulemaster.com
2006 S Main
Moscow, ID 83843

Tyler mentioned, "...that they are trying to find what causes the 97-2000 EBCM to have the "death code" C1255. Sometimes they have codes other than that and are occasionally fixable. As far as re-spinning the board, it would be possible, but the trouble lies in sourcing the IC on the board. It appears to be a proprietary flip-chip ASIC".

This could also theoretically be solved by using a programmable IC and writing an algorithm for it.

Our company is the leader in device programming technology. http://www.bpmmicro.com/

I will post an updates here as I receieve them.

Cheers,

Keep us informed Larry. A solution other than buying a used EBCM, if you can even find one, would be an instant hit around here.

It is actually an alumina substrate with several Flip Chip ASIC's.



You should ask Module Masters if they have the schematic?

The if you find the IC's the next trouble is sourcing what's programming on them. But yes, obsolete IC's are one of the issues that make it impossible to reproduce this controller without re-engineering it using newer components, which is a task that would cost millions of $$.

I also have a 1999 FRC that I like a lot, but also worry about the EBCM issue. I am no electrical engineer by any stretch, but normal economic forces should eventually drive a solution to this issue. Some bright person some place will devise a fix, and sell it to all of us that want a fix. What it will be remains to be seen, but I can't believe it is a problem without a solution. I wish you well and success in your endeavor Larry

Unlikely this will ever happen, the number of cars over time that will need this does not warrant the cost it would take to build new ones from scratch and if GM caught wind of it and decided to be nasty, they could pull the plug on it without a licensing agreement. You can't even get new replacement door panels for these cars, you think new EBCM's are going to happen?

But someone with the right influence and enough money can opt to purchase the patent from the original manufacturer and GM couldn't say anything about it, that is unless they happen to be the ones who hold the patent. Even then, if it makes good business sense to GM execs to make a short-term profit off of mothballed parts they could go for it.

It may be unlikely, I do not know? I do know that GM has egg all over their face with regard to ignition switch issues that go back a number of years. GM top execs getting fired, multiple accidents involving people getting killed. Give a good lawyer this issue, and a documented fatality or injury and how will that play out? I don't want to be morbid on this, but it will happen, and when it does and everyone points to GM knowing about this problem it will not be good for them. A licensing agreement will be of no concern then. One thing that may enter into it all, is what level of protection there recent bankruptcy affords them?

Manufacturers are only have to make parts available for 10yrs, after that, they are off the hook, the bankruptcy distances them even further. My point was, simple door panels aren't available for C5's, what makes you think an EBCM will be any time soon??

SO, look at cars GM's made a lot more than the Vette, many of those parts are no longer available either. GM licenses certain stuff after a while (generally exterior/interior parts), I though the EBCM were made by Bosch for GM which will make it more complicated.

The retooling cost to start making these again for the low number needed. Remember many of the 97-2000 C5 are beaters today, on the high end MAYBE $20K cars but many in the very low teens by now. GM sold these ate $1000+, can't even imagine how much it would cause to start making them again.

Well, if you want door panels try this guy. http://www.corvettepartsworldwide.co...els_s/1064.htm and I would expect them in the not-to-distant future from Mid America too.

and I am not trying to be a smart *** about this. But get any Corvette restoration catalog you want and look through it. All kinds of parts. To think that we are going to write off all C5's for this? Yea C5's may be close to the beater car, but so were the C1,2,3,4 at one point in time. As more and more of them need brake modules, I guess I am just optimistic that the same people that bring us parts for all the other old Corvettes will look at this issue and recognize a money making opportunity. Perhaps I am just to naïve about this, but I really hope not.

Anyhow, I gotta get back to work. Have a good day!

Don't hold your breath waiting, and there are a LOT of parts for old Vettes you can't get anymore, Try finding new parts for a crossfire injection unit or that 4 valve motor they used in the 1990's in the ZR1. How much would you pay for a unit like this -$2K???

Get over it, many old cars are kept running by the carcasses of other cars but eventually the pool of parts dries up, we'll have to get those guys from Cuba over here to show us how to band-aid cars with the guts of completely different models.

AND, if you look at those "door panels" it's one left side in black and a right side in gray, not exactly a great option.

Considering the cost of some of the classic car parts I've seen the return could very well be worth the investment. The initial rush of repairs from those who have EBCMs that have already failed might pay for the initial investment by itself, especially if this imaginary business owner took the old EBCMs in as cores that could be rebuilt and sold for a hefty profit.

Anything is possible.

Rebuilding would be the only viable option, reverse engineering the ASIC's would be the challenge and re-soldering them on the board. Take a lot of specialized equipment to do this and the test sets to run them through would REALLY be expensive.
