Last 2 mornings been very cold and truck didn't want to turn over even plugged in. Guessing batteries are going, starts fine once it warms up outside a little (teens). Anyway I checked for codes and this is what I got ECU codes230,236,1475,501,602. I also just installed my catcher ecm not sure if this has something to do with these or not. I have not done an APPS reset yet, not sure if it is needed. Any help would be greatly appreciated! Thanks Todd

 

I'm not sure what the exact codes mean but know that when the battery voltage gets low it will set off a bunch of them.
Maybe time for new batteries.

 

Get your batteries load tested, first. If any is bad, replace BOTH. Make sure you have good contacts at the terminals, check your wires.
