First check out fuses. You can also check ABS wiring, those who are in the inner side of each wheel.

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
