My 2010 2500 megacab 4x4 cummins w/ six speed tranny had a message come up first thing this morning saying "service trailer brake". It was gone after I parked the truck and restarted it later. The message came back up once more later but was off again after a restart. Anybody have any ideas what this means? I haven't pulled a trailer in about 2 weeks.
The problem is still intermiten. Hooked up my trailer and everything works fine. Then the display comes on again later. It is displaying CF on brake readout which I assume means check fuse but they are all good.
Saturday morning I went to start my truck and click click the batteries are dead. So after $300 and 2 batteries everything is ok. Apparently they were weak and causing that error message because it has not come back on. Just sucks that batteries only lasted 1 1/2 years and 44,000 miles.
