I have misplaced the manual for my 2000 C5 and wonder if someone could explain or point me in the right direction for clearing the codes so that I can start my car again. I have another post going on my current woes. Thanks for your help!

 

How to Pull Codes:
1. Turn your key to the "ON" position, but do not start the engine.
2. Clear any present messages by pressing the RESET button.
3. Hold the OPTIONS button down, and press the FUEL button 4 times. (This will get you into the "codes" section of the DIC.
4. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds. (Have a pen and paper handy to write down the codes)

Note: Any code that ends in an "H" is a history code (something that has occurred in the past, but is not reporting as an error currently.)

5. Once the computer has finished going through all of its codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# Codes."
6. To optionally reset codes once in manual mode, press and hold RESET until is displays "NO CODES."
7. Press OPTIONS to go into the next module (ie, from PCM, or Powertrain Control Module, to TCS, or Traction Control System.)
8. Repeat Step 6 until you have reset all the codes in all the computer modules.

Note: Only reset the codes if you want to- it is not necessary to reset them every time you pull the codes.

9. When finished, simply take your key out of the ignition.

 

Turn key to on position. Push and hold "Options" button. While holding options button press fuel button 4 times. This will start the diagnostic code check. Once done, use the DIC buttons to cycle through. When you get to the codes you want to clear press and hold "Reset" button until they clear. Push "E/M" to exit diagnostic mode.

Edit: Aw man, someone beat me to it.

 

 

I posted this in your other thread.....did you not read it?

You also did not post your codes. If you want help, post the codes.

 

If you clear the codes, will they come back if the issue isn't resolved? Like a TPMS system code??? I know I have one bad one but don't want to be reminded everytime!

 

Thank you all for your help!
