LIN technology is, a serial communication system which is used for communicating only one signal, developed to substitute CAN network, Normally used for multi signal communiction. It is only single wire to make LIN communiction in order to make simple network that is not important speed. PCM receives battery infromation such as battery voltage, current and temperature etc.) through the LIN, and uses these data as a information for controlling the battery status and charge.
PCM sets this code when there is difference between battery voltage at power supply terminal of PCM and the voltage from battery senor.
