CAN Communication System

NETWORKING: CAN COMMUNICATION SYSTEM: TERMINALS OF ECU

NOTICE:
* Turn the engine switch off before measuring the resistance of CAN bus main wires and CAN bus branch wires.
* After the engine switch is turned off, check that the key reminder warning system and light reminder warning system are not operating.
* Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the engine switch, any other switches, or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.

HINT
* Operating the engine switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.
* This section describes the standard CAN values for all CAN related components.

1. CAN JUNCTION CONNECTOR (CAN LH JUNCTION CONNECTOR , CAN RH JUNCTION CONNECTOR)

HINT
* The connectors connected to the CAN junction connector can be distinguished by the colors of the bus lines and the connecting side of the junction connector.
* The connectors can be connected to any terminals on the same side.
