Notes:
• The function of each pin is described later. Do not use the pins for other purposes than intended.
• Yanmar will not disclose nor customize the serial communication protocol.
• When the CAN bus is not used, jumper E30 to E39 to activate the CAN terminator resistor. (This is
required for connection of a service tool).
When the CAN bus is used, configure the bus according to the customer's CAN bus system.
• The intake air temperature, EGR temperature, FO temperature and reserved analog (atmospheric
pressure sensor) pins are not used and require no wiring.
