DIAGNOSTIC CODES on 2002 Dodge Ram Van 1500

I HAVE HEARD YOU CAN OBTAIN DIAGNOSTICS CODE BY TURNING THE KEY ON AND OFF. CAN YOU TELL ME THE PROCEDURE?

yes, if you cycle the key 3 times and leave the key on, then the light will flash out codes.
it will not define the problem, just the system that has a failure.

a scan tool is the real tool that is required as you need freeze frame data and data to help track down the failure.
