Hi Everybody ,
I left a dome light on by accident over the weekend. When attempted to start the truck the battery was really weak. Removed and recharged the batteries(they are almost new-2019). Now the truck starts right up with no issue but the check engine light came on.. On board system check gives me P20CD code. Is this normal after a battery removal?Do I need to reset something? I drove the truck for more than 100 miles since the battery recharge.Charging system and battery voltage all are normal.Prior to battery drainage the truck was running without any issues at all. Thanks

I don't know Hino's but that is an after treatment code. It won't clear itself after just one drive cycle. Just keep on driving, it'll take a few.
