What is wrong with my GMC Sierra 2003 pickup? Clock keeps resetting and I get "check
brake system" message.? I turn my truck on and notice that the clock is reset(midnight); happened two time today. My display is showing "check brake system" yet brakes are fine. This happened once today but has yet to do it again. I tighten the battery cables this morning but it still reset. It is a diesel with two batteries. Don't know what problem is.
