Drove from Va to Sc yesterday, no issues. Went to start truck this morning and it won't crank. Battery is charged, key turns but nothing happens. Tried starting in park and neutral. "Service trailer break system" message has come up. Towed last weekend without issue, have not seen this message before. Stuck at family function now, will check fuses and hook up scanner when I can in a few. any suggestions or starting points are greatly appreciated. Trying to find a dealer near where I am, but anything local is most likely closed until Monday morning.
