This error stays consistently on the obd tester but only affects the truck every so often where it will turn off the radio and the hvac and cluster will shut down. When it comes back it goes through an initialization of unlocking and locking the doors then the cluster comes back reading things like service 4x4 and service stability. Only happens about 5-10 times a year for the last 5 years. I just really need help finding the wiring diagrams for this. Thanks

Cruise control not working. No light indication appear on the dash. I have changed my brake switch along with my multifunction switch and the cruise is still not working. All of my signals and lights are working as they should. Please help me solve this problem.
