Would someone please tell me what "P done" means. I have a stock 2001 2/4 ton 5.9 diesel. Well almost stock, there is a quadzilla max mileage unit.
I turned the ignition switch on and off 3 times and read something that says "P done"
Thank you.

 

P done means you don't have any codes stored.

 

That essentially means you have no codes. But the key on/off trick isnt reliable. Invest in a good scanner or a SMARTY to check and clear codes.

 

P = power train.
