Decoding is very easy through stockmopar.com or mymopar.com. Mymopar.com only goes to 74 so you'll probably want to use stockmopar.com. There may be some inaccuracies but not enough to matter in most cases. There are other sites where you can decode also.

Yeah. I love the stock MOPAR one. One wrong code and you’re confused as hell.
The problem with on line decoders is they do not use any true/false or if/then logic. They just repeat what’s been input.
They do not account for variances between years.
