2012 Lighting issue
Headlights and taillights won't turn off and foglights on when key is in any position after boat trailer went in water. Dtc code shows U0422 invalid data from body control module. Need new BCM?

Now boat trailer is disconnected and same issue persists?
Did the trailer plug (on the back of the truck) enter the water at all?
Year/make/model of truck?
What engine and transmission?
How many miles on it?
