Four CANBUS states are possible:
Active: CANBUS is running without any problems.
Passive: Passive errors have occurred.
Warn: BUS Warn errors have occurred.
Off: BUS Off errors have occurred.
If one of these errors occurs, display records number of times that it happens.
Additionally, display records Overrun Error Count.
If value counts up higher than zero, a controller on CANBUS did not receive all messages. Important information might have been lost.
This is most likely due to high CANBUS Utilization.
Check wiring and connectors for connection problems. If there are no wiring problems, perform a cold boot. If problem persists, contact a John Deere dealer.
If value counts up higher than zero, a controller on CANBUS has issues.
Check wiring and connectors for connection problems. If there are no wiring problems, perform a cold boot. If problem persists, contact a John Deere dealer.
If value counts up higher than zero, a controller on CANBUS has issues. It missed a certain number of messages and does not receive messages anymore. Important information has been lost.
It most likely occurs in combination with high CANBUS Utilization.
Check wiring and connectors for connection problems. If there are no wiring problems, perform a cold boot. If problem persists, contact a John Deere dealer.
Overrun Error Count indicates that applications or controllers on CANBUS receive messages faster than they can process them. This results in missing messages and malfunction of the system.
It will most likely occurs in combination with high CANBUS Utilization.
Check wiring and connectors for connection problems. If there are no wiring problems, perform a cold boot. If problem persists, contact your dealer.
