    Is there a way to reset Engine Check Light without going to dealer?

    Yes there is a knob on the right side of the steering colum. If you rotate it to the right you will see in the top center display a list of differnt settings. when you get to trouble codes press the knob in once. It will tell you the code. and what it means. Then if it's something easy to fix like low coolant level for instance, Then fix the problem and the check engine light will go out. Otherwise it's gotta go to the dealer or someone that can scan the ECM. Hope this helps Bill

    Thank you, Iron Pony. The problem is that truck may not see dealer for a while. I was wondering if there is some “magic” combination of pedals and buttons to press and turn to reset CEL. For example: to get faulty code you can also turn ignition on with engine off, wait a few seconds and press gas pedal 3 times. Stop engine red light will blink the code. In my case it was 3725.
    If I run with CEL on, how will I know about a new fault?

    There is no magic combination like there is for the service light for cars (oil change interval). If the check engine light starts flashing it is telling you that the problem is severe and that the engine could be damaging itself.
