How do I pull up a code on my 2001 2500. it's got a CEL and I got some dead pedal the other day. I'm at the fire station so I'm hopin I can check it on the odometer but I totally forgot the procedure. If you can help I'd really appreciate it.

 

Key on & off 3 times I think.

 

On and off twice followed by turning back on. Be ready to copy codes in case you have more than 1.

 

Borrow a scanner form one of the chain stores. You get more info than the key on procedure.
