Connection to engine
This section describes the engine interface for the different engine types. The engine
interface is configured differently, depending on the engine type.
If the customer has not ordered the Scania base system, the customer must connect
his system to the engine interface himself.
Connection to engine without Scania base system
The CAN cables must comply with SAE J1939-15, i.e. they must be unshielded,
twisted cables (40 turns/m). Maximum recommended length is 40 metres.
The engine control unit has an integrated resistor of 120 ohms. In a CAN network,
two resistors must be located between the CAN cables (CAN high and CAN low) at
the ends of the CAN bus. The Scania coordinator has no integrated resistor.
Therefore, position a resistor of 120 ohms as close to the other end of the CAN net-
work as possible. The Scania base system has an integrated resistor of 120 ohms. As
a result, a resistor is not necessary.
