That's great, but I wonder why they would be making them for the 97-00 models?

JR-01

They aren't.

grampi50, because of the design. The re-design in 2001 changed the electronics. The new design is not impregnated with material (epoxy??) that the previous design had. Consequently, it's easier to repair. Also, the newer ebcms are more robust, thus failing less frequently. I'm surprised someone is building them as there is much less of a need for the newer design. They fail less, of those that fail the repair rate used to be as high as 80% recoverable. I'm told it's actually higher now because the repair firms found a way to repair some of the electronics they couldn't repair before. I don't know if that's true, but the recovery rate still remains high. Now add in the ebcms recovered from 01 to04 wrecks and that's quite an inventory. If someone is remaking the 01-04 ebcm, I doubt they reversed engineered it, they probably obtained the original plans.
With regard to the 97-00 plans, there was a thread back around 2015 that claimed there was a fire at the GM subsidiary that designed the ebcms and the plans for all three early versions were destroyed. I don't know if that's true however, there is much more monetary gain reproducing the older versions than the newer versions because there are so many newer versions available.
I used to be right on top of this when I owned my 04 C5. Although I've moved to a C7 in 2016, I still stop to look at and admire C5s at Cars N' Coffee. I still like them.

I believe it is the original equipment manufacturer that is building the Delco EBCMs in Mexico. They probably have a supply of the parts needed and are building to order. When the components are gone they will probably discontinue the part.

I'd agree. Extra parts or the parts were still available so it was relatively easy to keep manufacturing.

It definitely isn't a reverse engineered or re-designed part selling for ~$300 a pop.

anyone plea weigh in with an opinion. I have a low mileage appx 11,000) 2000 C5. I am getting the warning message and codes associated with what appears to be a faulty EBCM. How is this possible on such a low mileage car? Simply the coating expoy that was used has created the problem even with lower mileage?

JR-01

I have read that low voltage can burn out a relay in the module. Was a battery tender used on the car since it must have sat a lot during it's lifetime?

You might want to check with other C5 owners about the wire connections and a potential corrosion problem, especially with a seldom driven car. I know of at least one 98 C5 that threw a code but it turned out to be a connection had corroded. Another had a wire pinch also threw a code. To the best of my knowledge, those ebcms are still working with those cars. I would exhaust all other options before assuming the ebcm is gone.

My 03 EBCM died around 33k. I don't think it is milage but rather age.....

You could contact ABSfixer but I think they only do 01-04 Vette EBCMs

Sorry, my post was supposed to read "wouldn't"...

Check your battery. I got the same error codes, but it was just because my battery needed charged a little more.
