Abstract

An M/F switch diagnosis method through monitoring BCM(Body Control Module) input signals is provided to prevent a risk and an accident resulting from a fault of an M/F switch by providing a driver with fault information when the M/F switch is out of order. An M/F switch diagnosis method through monitoring BCM input signals includes the steps of: sending a 5V output signal in a neutral state of an M/F switch by connecting a neutral terminal of the M/F switch to a 5V output; determining that the M/F switch is out of order when no input signal is received or multiple input signals are received by determining a turn signal in a state when a BCM is prepared and an ignition is turned on; and performing a trouble shooting operation activating a turn signal lamp corresponding to a fault state, activating a buzzer, turning on a cluster, or outputting a DTC(Diagnostic Trouble Code).

It relates to the diagnosis of the fault through the output signal of the terminal.

일반적으로 BCM(Body Control Module; 차체제어모듈)의 대부분의 입력신호는 M/F(Multi-Function) 스위치로부터 LIN(Local Interconnect Network) 통신을 통해서 받게 되고, BCM을 통해 출력되는 출력신호는 드라이버 회로를 통해 각종 릴레이, 모터, 액츄에이터 등을 구동하게 된다.In general, most input signals of the body control module (BCM) are received from the M / F (Multi-Function) switch through LIN (Local Interconnect Network) communication, and the output signals output through the BCM are driver circuits. By driving various relays, motors, actuators, and the like.

그런데 종래에 있어서는 BCM에 출력단의 램프가 고장난 경우에 대해서 고장을 처리해주는 고장검출회로가 포함되어 있지만 입력부인 M/F 스위치의 고장을 진단하여 처리해주지 못하는 문제가 있었다.By the way, in the prior art, the BCM includes a fault detection circuit for handling a fault in the case of a failure of the lamp of the output stage, but there is a problem in that it cannot diagnose and handle a fault of the M / F switch as an input unit.
