The whole EBCM & SPS thing really pisses me off and sort of scares me.
My car is immaculate and in perfect running order minus the fact that the cruise control doesn't work.
But if I'm reading things correctly, all it takes is for one of these things to fail to leave my gorgeous car sidelined indefinitely?
If that's the case I'm putting it up for sale tomorrow because the last thing I need or want is a $12000 paperweight.
So, honestly, what are the options for people facing these failures? It really pisses me off that GM has provided no recourse for loyal customers with these issues.
It doesn't become a paperweight, with a bad EBCM, all you do is lose traction control and abs. My Talon TsiAWD doesn't have either and is fine to drive.

It may be an inconvenience, but you can still enjoy the car.
2001 and later. NOT the 97 - 2000. Early year EBCM had a potting material placed over the electronics after manufacture and it is near impossible to remove that material so that a repair can be made even as simple as resoldering the main power relay.
Unscientific though it may be, it would be interesting to set up a poll here for `97-`00 owners to obtain at least some idea as to what the failure rate is, percentage-wise, on the ECBM from these years.

I've been driving around in a '99 that has been having EBCM issues for the past three years now. 15,000 miles later and still drives the same.
At the absolute worst other than losing full functionality of ABS and active handling I have to constantly hit reset on the DIC on start up. Otherwise I go about my business.
There's a good sticky in the tech section of a pre-2001 car being retrofitted with the post-2000 EBCM setup. This at one time was believed to be impossible or very difficult but a forum member proved it can be done. It is very involved however. I'd surmise that eventually vendors will come up with a retro-fit kit. The only major issue will be 1997 and 1998 cars are a "unique" bag because they have an entirely different ABS layout, along with other differences, than 1999-2004 cars.

The later model ebcm's have been successfully integrated onto the early cars. I read the entire thread and while somewhat complicated, it seems a viable option.
Didn't read all of the above thread, so what VV said. 👍
