'97 Coupe with ECBM
I will get the dreaded ABS and Traction Control warnings every once in awhile, I reset the codes and the warnings would disappear for a week and up to 2 months. I would pull the codes most of the codes would have the H at the end, except for one (B0432 Rear Defogger Relay Circuit).
Two questions.
I have read that '97s show the warnings, but its not an accurate reading. Just a glitch?
If the above is incorrect. Can the '97 ECBM be fixed?
Thanks
Robert

A little history about me, this is my 4th Vette (2 - C4s, C-6 & now C-5, Goal is to have one of each group. Bucket list). I am able to work on the Vette and can do most things (5 out of 10).
Your help is very much appreciated.

I would say check your "grounds". I bought a 97 about 3 months ago, it had been sitting for a while. Seems like the more I drive it the fewer codes I get. I cleaned up some of the big ground connectors . If I hit a large bump or pothole I still get a traction control / abs code. Search the thread about "cleaning grounds". This is a good cheap place to start.I al so show 13.2 volts on my dash, it should be 14+ with the car running. Again this is a wiring issue. I have a good battery and alternator. I think if I run some better ground straps and positive leads to bring the voltage up, the electronics wont be so quick to throw codes. seach "big 3" a lot of info about how the C5 needs better wiring.

All the loss of comms codes points to a bad connection in the serial data link. Common spots where the wiring gets damaged are in the door to body accordions and under the seats. You can pull the rubber door accordions out at the ends and then pull some of the harness so you get a look at it. You should find a connector you can look at too. A search here will get you lots of pics and info on this. Basically, make sure there is no frayed wiring and pull the connector apart and make sure the connectors aren't damaged. There's a little tab or spring in the female end that puts pressure on the male tab and sometimes it gets bent back so it doesn't grab.

I have found that Lionelhutz seems to have quite a bit of knowledge when it comes to the C5. He seems ready to help in many situations. I gave him some $hi# a while back and wish I had not. Lionelhutz, I apologize. Rod
