General Description

This is DTC which is related with communication error between BCM and other units.

※ Body CAN communication Control Units : BCM(Body Control Module), PSM(Power Seat Module), SMK(Smart Key), SJB(Smart Junction Box).

The controllers are mounted on the vehicle communicates others by CAN(C-CAN) communication way to share information and control their logic. the C-CAN communication is connected with two wires phyiscally to send information.

In order to successfully perform CAN communication, BCM and EMS ECU(PCM) are equipped with an internal 120Ω termination resistor. BCM sets the DTC related to CAN Communication when the CAN communication does not fail by any cause.

*¹ CAN (Controller Area Network) : CAN is serial bus communication type which links not only communication system but also control units each other.

*² LIN (Local Interconnect Network) : LIN is serial communication type which is used in electrical control system. (This is less expensive.)
