Does anyone know if the C5 tools like Ease Diagnostics work on the C6? I haven't had a chance to try mine yet. If so, you might be able to find someone in your area who could "hook you up".

Yes you could display and translate the error codes in all C4's as well without any special diagnostic gadgets. In the early C4's you would need a piece of wire about 2" long. I usually used a piece of speaker wire, you ground the A and B terminals in the ALCL then you would just count the number of flashes of the Service Engine light and that would be the error code number, very simple procedure.

OnStar... Not Much Help
I went through the OnStar registration process today. Part of the 1-yr free service includes remote diagnostics, so I set them loose on trying to figure out the Check Engine Light problem.
The Good: The OnStar rep was positively ecstatic that I had a 2005 Vette, and went into a lengthy monologue about her experience with her friend's C4, including how she beat a Honda in a stoplight duel
. Then, diagnosis complete, she informed me that there was an error code in the PCM.
The Bad: She didn't have C6 code info, and couldn't translate the code.
The Ugly: She refused to give me the code, saying that they're only allowed to give it to a GM technician.
So I guess we'll find out why my 3-day-old car is still showing the Check Engine light on my Tuesday service appointment.
Anyone figure out how to pull up C6 codes in the DIC yet, and a key to translate them into English?

Last year I bought Autotap for Palm PDA. This has become a priceless tool for troubleshooting and monitoring of my LS1 engine with its nitrous oxide system. For those of you without Autotap, go to Autozone. They retrieve error codes for free. I did this several times before I bought Autotap.

Hope your check engine light issue is resolved. Not being able to pull up codes on your DIC ala C5 is a HUGE step back for owners. With a C5, you pull the code, post it on the forum and within 5 minutes someone will tell what is going on with your vette. Now, you need to purchase and subscribe to on-star, purchase expensive diagnostic tools, and/or rely 100% on a dealer. Then you hope to heck the C6 doesn't crap out completely before the appointment (or you take your chances and continue to drive it hoping you are not causing additional damage), and hope to heck the dealer doesn't screw up 50 other things on your car while he is clearing a silly code. Will the dealer/GM deny warranty coverage for any additional damage caused if you continued to drive when some light came on that? Are they expecting people to park their C6s until the earliest scheduled appointment which might be days/weeks away. What if your C6 is your only vehicle. Who picks up the tab for the rental car while your C6 is parked until appointment date. What will happen once the warranty runs out. Will all shops have the required diagnostic tools available to properly troubleshoot your C6 or will you be forever taking the vette back to the dealers. Hardly progress as I see it.

i agree 100% (see my homepage)
but i will suggest,
1. with 441 codes and each having 80 sub-codes, who is smarter you or the computers? does a coolant sensr need 80 sub-codes?
2. any good mechanic doesn't need any codes. often they are just an excuse to replace a part that is good, but has a bad connection.
3. everyone wants to make money in stocks, so, use this info to buy stocks that will profit.
4. frequent the trash bin at dealers and collect sensrs that are thrown away. many are good.
5. common problems will still be solved by forum members.
6. clean sensor contacs
7. buy an old car for back-up, also handy for snow, rain, bad neighborhoods

PLEASE DO NOT CLEAR THE CODES!!!!
GM is going to be keeping a close eye on problems with the new C6
If there is a code TAKE IT IN!!! It's free!
As far as the comment about replacing good parts for a bad connection.... Have you taken a look at the weather/oil/heat resistant connectors on your car??? It's pretty rare to see a wire or connector failure in a car that has not been wrecked!!!

Yeah you could... on my 93, the procedure is to use a paperclip to jump the A-G terminal on the ACLC under the dash, and you could cycle through the codes on the LCD readout. All you needed was a chart to reference the code #'s since the LCD doesn't display anything more than the number, and whether it's a history code.

If you wish to try to reset, connect the battery cable on the car to another car and jump start it. Let it set for a few minutes. Disconnect the battery. You will need to to take your car into the nearest chevy dealer..
Now, simply start the car and try again. If it doesn't start you need to call a tow truck. If the check engine light resets there is a problem that the dealer service center will have to diagnose.
When brand new and learning, with American cars this can happen. A complete reset such as this will not end the problem. But you really need to get a quality car that's even better a S2000 Honda
That will solve all of your problems and sell the fiberglass junk
Too bad for you!!
