U0068: The Low-Speed Can Communication Bus Off
The U0068 code is related to the Controller Area Network (CAN) bus system in a vehicle. The CAN bus system is responsible for interconnecting automotive devices without a host computer.
The U0068 code sets when a supervised periodic message that includes the transmitter device availability has not been received.
This fault code specifically relates to the Vehicle Communication Bus ‘E’ (+) High.
The CAN bus system uses two dedicated wires for communication, CAN high and CAN low.
When the CAN bus is in idle mode, both lines carry 2.5V. When data bits are being transmitted, the CAN high line goes to 3.75V, and the CAN low drops to 1.25V, thereby generating a 2.5V differential between the lines. The CAN bus system is not sensitive to inductive spikes, electrical fields, or other noise.
