Last week my wife was driving my truck for a 5 hr trip. When she arrived the CEL was on. I wasn't able to scan until Monday.
I'm assuming this is as simple as a bad ground or loose wire. Anyone have any ideas?

These were Mondays codes:
(WARN) [08:26:45.810] DTCs in PCM: P04DB:00-ED
(WARN) [08:26:46.423] DTCs in OBDII: P04DB-C

(WARN) [08:27:22.610] DTCs in OCS: U024C:00-28

It might help if you identified what you're working on....
