Living with EBCM Failure
I am thinking about buying a car with this problem and would like to make sure I know what I would be getting into.
I understand there would be no functioning ABS, traction control, and active handling. I am completely fine with this part of it.
I understand some states won't let it pass inspection while the problem exists. That's not a problem in my state.
I know that the DIC will be constantly reminding me and throwing codes. How does this work? I assume I get a message at start up. If I hit reset, does it go away and leave me alone for the rest of that trip, or will it pop up randomly while driving?
I read somewhere around here about an 80mph limit. Is that the case? Is that only while the warning light is on? Will hitting reset remove the limit for that trip, if it does exist?
What's the most annoying part of living with this issue?
I would really like some input with those with personal experience.
Thanks

I had this failure in my coupe.
All I had to do was hit reset after start up and it wouldn't pop up again until next start up.
The small traction control light does stay lit in the gauge cluster tho.
I personally wouldn't let this failure deter me from buying.
Not a big deal IMO unless you like going to cars & coffee in Dallas lol

Does this not put the computer in some sort of limited mode? I thought I read that on the forum somewhere. I just want to make sure the car doesn't drive any differently. I don't mind hitting the reset on every start up.
It does NOT limit the speed to 80 as your earlier post mentioned. There are other failures such as for the F45 suspension RPO that do that but not an anti lock brake controller failure. Only driving difference is no anti lock brakes, no traction control and no active handling if it even had the JL4 AH RPO.
That leads to another question, though. If the also unrepairable SWSP fails, is that one of the other failures you are referring to that would be a problem?

You couldn't find all the parts inside, many are NOT marked in any way and even if you knew what they were finding them would be tough and of course the ASIC's would be impossible to source.
This will only get worse as cars have more and more complex electronics with finite lifespans. There will be a lot of nice looking cars with no way to repair them and if the OEM won't license the tech for others to fill the void for this stuff your SOL.
The "potting" is the problem. We use components similar to that in the military. We called them 'mil spec' and I always figured it was for two reason, waterproofing and bigger profits for the manufacturer.
Negotiate the cost of a new EBCM into the price of the car and fix it. Its easy, the part goes for almost a grand though.....
Assuming your looking at an early C5. A later '02-'04 is a $150 fix.

The Chevy dealer doesn't have the part. The part is not being made any more. It can only be found used on Ebay or from a scrap parts dealer that happens to have one.
