West Tennessee | With 3 codes related to one controller I would unplug and plug back all connections at that controller and see if that does anything. Had a similar issue on our 9770 one year and that fixed all the codes and issues. Otherwise I would start through the diagnostic process on one of the codes. Probably find your issue somewhere in the process. Dealer "should" be able to print the process off from the diagnostic and repair manual for you if they will. | |
