AutoHex Online Help: Hyundai VERACRUZ/ix55(EN) 2012
Component Location
General Description

The 6 components related with Body Control Module(hereinafter referred to BCM) connect with each other via CAN(Controller Area Network) communication system

These are BCM. Assist Door Module (ADM), Drive Door Module (DDM), Power Seat Unit (PS), tilt/telescope control unit and Personal Identification Card (PIC).

Wiper Motor Module (WMM) and Mulit-Function Switch (M/F) connect with BCM via LIN (Local Interconnect Network). Therefore it is possible to diagnose an overall system with scantool.

*¹ CAN (Cotroller Area Network) : CAN is a serial bus system especially suited for networking "intelligent" devices as well as sensors and actuators within a system or sub-system.

*² LIN (Local Interconnect Network) : LIN is a new low cost serial communication system intended to be used for distributed electronic systems in vehicles, which complements the existing portfolio of automotive multiplex networks.
