I have a Check Engine light issue, it came on sometime last year. I recently pulled & cleared the codes, but it reappeared about the same time I had the bare-serial-data-wire-short-in-the-accordion-door-tube issue, making the DIC go haywire. Jiggling the accordion tube made it go away, and I've since purchased some liquid tape and re-pulled the codes. Here they are:I can't clear one of the TCM codes; I'll have to check which one tomorrow morning.

Thanks in advance,
Anthony

Ck this for your TCS code - http://forums.corvetteforum.com/c5-t...cs-1214-a.html

And this for the PO410 - http://forums.corvetteforum.com/c5-t...t-go-away.html

Good luck

Didn't rearch at all but 1096, 10, etc are bad grounds, probably at G105 located under the block on the driver's side. If this ground is loose,,,,gobbs of problems can result. Don't ask how I know!

Given the OP's codes, G105 is not a likely suspect. G105 grounds the O2's, fuel pump relay, and oil level sensor.

1214 is the EBCM relay on it's way out.

Thanks all, I've had the ABS/TCM warning lights/messages for at least a year now, been ignoring 'em for the most part. Looks like I'll be shelling out the $$$ for the ABSFixer.com repair, looking at the site now.

Another procrastination issue is my cleaning the grounds - I finally found a thread that shows me pictures of where they are! I have the service manuals ('02 Coupe) but it's so damned hard to find stuff in 'em. Still dreaming of a PDF version (shouldn't be a copyright issue since I have the original paper version)...

I suspect the vacuum line under the battery tray for the AIR / check-engine light issue, because my HVAC also isn't delivering much air from the vents (even on high fan) and I believe that vacuum line may also control the blower doors & stuff, or whatever they're called. Also just shined a light in the battery compartment & I've got crud in there I just bought that Optima battery like a year ago!

Thanks again all,
Anthony

If the vacuum line is fubarred, you'll only get air out the defrost vent-fails safe so you can see.

It was the vacuum line under the battery tray - well two of 'em actually. Both were pretty much shredded and brittle to the point that pulling on them broke the line. I had to get to the vacuum reservoir in the right front fender area near the battery to see everything. At this point I've only replaced the damaged vacuum tube sections, but I think I'll have to run new line :-(

I've got a bunch of pictures and wanna do a writeup to try to help anyone wanting to replace the line, just gotta find the time. Next is insulating the bare serial data wires in the door accordion tubes, then the ignition contacts repair. No work on Sundays? God must not've been a Vette owner.

...oh, and apparently I did not splurge for the Optima battery a year ago, I got the next model down... grrrr.
