Location of the CAN CONFORT network ECU
The CAN CONFORT network is the interface between the driver and the vehicle systems.
Data transfer rate 125 Kbps (Low Speed).
Continuous transmission of information across the entire CAN CONFORT network.
A CAN CONFORT network is a network in which each computer constantly transmits various information to the entire network as a whole.
The control of the network connection and the establishment of the "+ CAN" power supply is carried out by the switching unit (BSI 1).
The computers of the CAN CONFORT network have their own termination resistance and are connected to the power supply, depending on the case, either "+ CAN", or "+ BAT" or "+ APC", which comes from the BSM.
Note: Open circuit in one of the two wires or short circuit between the wires "CAN CONFORT High" or "CAN CONFORT Low" carries out communication over the network, providing information about the error.
Note: The thick line represents optical communication, the triple line represents multiplex network.

CAN CONFORT network voltage level (oscilloscope readings)
Original published on the portal: Peugeotbook.ru
- "M": CAN CONFORT high.
- "N": CAN CONFORT low.
Voltage: 2V.
Time: 1 m/s.
Test conditions:
- the engine is not working;
- ignition is on.
Results: variable pulse packets display information transmitted on the high (High) line of the CAN CONFORT network.
Note: The CAN CONFORT Low signal complements the CAN CONFORT High signal.
CAN CONFORT Low signal voltage levels:
- low level - 1V < U < 1.4 V;
- high level - 4.8 V < U < 5.6 V.
CAN CONFORT High signal voltage levels:
- low level - 0 V < U < 0.2 V;
- high level - 3.8 V < U < 4.2 V.
