05 mounty all warning lights on, message center listing long list of codes/problems.

Anyone have a clue? Daughters car, V-8 approx. 150k, been running fine, started problem yesterday, starts up fine, but all warning lights are on, and message center displaying long list of codes and computer jargon, ends with check telltales???? Reset with scan tool, everything seemed normal, next start-up same thing again.

@Byker Does it continue to run normally despite all the warnings? If so, has it been driven for a reasonably long distance with the warnings present? If not, and it is attempted, it sounds as though it may be a candidate for "Forced Limited Power", AKA Limp Home. Not a fun thing to experience. What are some of those codes displayed? imp

Thanks for your reply, I think the problem is solved. As this is daughter's vehicle, at least part of my info was second hand. Tested battery, and was amazed that it would still start. Replaced it, re-set with scan tool, all seems normal again. Never seen this before, apparently low volt at start was triggering the problem. Anyone else ever seen this?

@Byker
I believe I've heard of low battery voltage causing some unusual things. As you said, surprising those events happened even though the battery had enough voltage to start the engine. imp
