I have a Thermo king SB-210 with about 15k hours on it. I was recently driving with my reefer on and when I parked I came outside to an off unit with a message of "Communication failure lost controller connect". I initially was thinking maybe there's a wire that came loose with the rough drive, so I restarted the unit and it was running for about 2 hours with no movement and I got the same message again. Any ideas?
Thanks in advance!
