Check Engine Light - no current code
My check engine light came on tonight going to grab some food. 40ish mph in 5th gear. I just checked the DIC and there are no current codes but the #$@$ check engine light is still on. So my question is....
1) what is wrong?
2) how do I fix that?
3) how do I turn off the CEL?

You can acess all of the cars trouble codes from the dic and erase them! I know it works on my 99 but, I am not so sure on the earlier C5's. Here is what you do: Press and hold options and then press Fuel 4 times while still holding the options button you must do this quickly. A message will appear saying "Diagonstics" then it will automatically read off the codes. Like....02-PCM(No codes)....03-BCM(No Codes)...ect. if there is a code it will look something like this 02-PCM (1052H) NOTICE THE H at the end of the code, That represents a code that has happened in HISTORY. If there is a C after the code it is CURRENT. To clear the codes let it automatically cycle through the codes then it will come to (MANUAL DIAGNOSTICS) this is where you can clear codes. Use the options button to scroll forward and the TRIP to scroll backward find the code(s) to be erased like 02-PCM (2Codes). To erase this, press and hold the reset button until it says "NO CODES" There you have done it!!!. To exit the Diagonstic menu press the METRIC BUTTON!!!
