Stuck in Park with "Service Trailer Brakes & ABS" error messages

[Wldcrd03]

Came out to truck yesterday, started it, and noticed a "service trailer break system" and "Service ABS system" error messages and dash lights. Truck would not shift out of park. Let truck idle for approx. 15 minutes, messages went away, dash lights went off, and truck would shift out of park. Today, started truck with same issues occurring but message never went away and truck will not shift out of park. Has anyone else had this problem? If so, what was the cause?

Someone on here had some sticks stuck in theirs and it damaged some of the wires. Take a look under your truck for connectors or wiring problems.
