Something that is not easy to check on these and often gets overlooked is the alternator, as you have to lift the cab to check it out.I would suspect a bad battery as you needed to jump it. It could be the battery or even the alternator not charging or over charging causig the error on the panel.
Personally i would charge the abttery over night and see how it performs in the morning. If it still needs a jump to start, get a new battery.
