Information on CANBUS is sent in messages between controllers. The John Deere implement CANBUS is running at a baud rate of 250 kbd, meaning it can switch power up to 256,000 times per second to transmit messages. This is a BUS utilization of 100 percent.
If a controller, such as an implement, is not running as expected, a BUS utilization of 45 percent or higher could be a reason for the issue. Some devices cannot send and receive all necessary messages due to high BUS load.
NOTE:
Some ISOBUS implements do not work with BUS loads higher than 25 percent.
A working StarFire GPS receiver causes a BUS load of about 5-7 percent.
Unplugging implements or GPS receivers can reduce the BUS utilization.
