Southeast MN | Working on setting up a camera system while in the shed (multiple key on/off cycles, sometimes starting engine) over the past couple days.
Tonight, went to start the tractor and it throws the error code 19742 and yellow warning symbol. Online, I found the following info for the code:
DCU 19742 Main Relay opens too early / too late _main relay shut off too early (before EEPROM update) _ P0685 ECM/PCM Power Relay Control Circuit /Open
P0685 seems to be a more universal, automotive code for "P0685 ECM/PCM Power Relay Control Circuit Open" and can find some suggestions for that on cars/pickups.
Before I talk to the dealer in the morning, is there anything I can check?
Much obliged.
