I have a 2006 Chevrolet C4500 Duramax Diesel and I would like to know how to turn off or reset the check engine light on the truck.
You can either bring it in to a Chevy dealer or use a programmer/tuner to reset the check engine light.
Depends cummins powerstroke or duramax or even a little TDI Jetta are all different
How do you reset check engine light for the 2009 Chevy trail blazer?
You must have an engine scanner to do that.
It requires an engine scanner to do that.
A flashing check engine light is an indication of a misfire.
Check

To find out why its on you'll need to either take it to a dealership or run a tuner on it and run a diagnostic check on the truck.
If the check engine light is blinking that means an engine cylinder misfire has been detected
That REQUIRES an ENGINE SCANNER to do that.
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.
