Code P1635 came on on my F350 this morning while parked in my Drive Way

Question

This code caused the Check engine light to come on.  It came on right after I had to jump start the truck, it appeared as if the power was totally lost.

Answer 1

If the battery was totally lost and a jump start, was needed you need to check the charging system , as well as to check that the battery can hold a charge. P1635 for this year is not really valid , This year it would use P163A, or P163C or P163D. in either of these 3 codes all require that the battery be sufficiently charged and capable of holding a charge and a adequate charging system
