It seems like there might be an issue with the CAN Monitor Unit on the John Deere AT320355 AT320694. I'm not entirely sure what that part does specifically, but it looks like it may have stopped working. We should probably have a technician take a look to diagnose the problem accurately. —> …Purchase or Repair: Ticket Image...
