Electrical Continuity Of The Networks - Fiat TIPO Handbuch

The ACC module is connected to the Half module via a dedicated CAN-C line. The reason behind the
dedicated data transmission line between the two modules is the continuous exchange of information
between them during operation of the cruise control and of the FCW function.

Electrical continuity of the networks.

The three digital networks CAN-C1, CAN-C2 and CAN-BH have 120-ohm terminal resistors. The
electrical continuity of the networks can be checked directly via the diagnosis connector by setting the
multimeter to the Ohm function. When the network is electrically continuous, the value that the
operator needs to read on the display is approximately 60 ohms for all three networks.
