Is there anywhere in this forum where the diagnostics are listed for EVERY Dodge Module... all in one place? This should be a permanent post (sticky).

Particulary... how to enter diagnostic mode... or state that there is none... and maybe a link to the Error Codes (which are easier to find).

PCM Powertrain Control Module
ECM Engine Control Module
BCM Body Control Module
ATC Control Module
FED

I have found that looking for Error Codes and Diagnostic Modes is not an easy task here.
