Good question. On the C5
Now having said all that, you should find that in the tech tips along with several code values and their meanings.
Does all this work on a C6? No clue, let us know.
- Key to start, but leave the engine off
- Press and hold the Options key
- Press the Fuel key four times
- That will scroll all systems.
- Press 1 (Fuel), 2, 3, or 4, to enter manual mode
- In manual mode, use 3 to move forward, 4 to move backwards through each system
- 2 to move down, within a specific system, 1 to move back up
- Reset key will clear codes (press and hold)
- 5 (English/Metric) to exit diagnostic mode

Not sure what the problem is on your car but at the NCRS National they had to put GM's Silver C6 Conv. back onto there truck because they were having technical problems and the car wasn't even on, it was parked.

I have had my C6 for 12 days and still do not know the answer, being the system does not operate the same I have not figured out what sequence you can get the DIC to display any DTC info. Additionally I do not know what codes the system can display if it can be done by the user. Someplace I did see there were 81 trouble codes for the C6. Unless we have a GM tech out there we might not know for a while if this option is even available on the C6.

You can probably use the 'ol low tech solution to clear the code.........disconnect the battery for 10 minutes, reconnect, and see if it comes back. .

Computers computers better buy that fine 69 427 big block instead at least those are more accessible and easier to work on and don't depreciate.
