PURPOSE: An error signal conversion module and a conversion method thereof are provided to operate an HECU unit and an HAC part even in a situation that the yaw rate is equipped in a wrong way or assembled in an opposite way. CONSTITUTION: An error signal conversing method for a yaw rate sensor is as follows. The engine of a car is started(S11). An ECU unit determines whether the start of the car engine is the first or not(S12). The ECU unit is equipped in the yaw rate sensor signal corrector which determines whether the G value of yaw rate sensor is positive or negative number(S14). When the G value is not the same as the setting number, a parameter is produced to change the G value into the same setting number by the yaw rate sensor signal corrector(S15,16). The yaw rate sensor signal corrector multiplies the G value of the yaw rate sensor with the parameter(S17) and the value is put into the ESC unit(S18). The G value is the value on the vertical line or on the horizontal line. Before the first step, the setting number is set into the positive or negative number by the ESC unit. Before the third step, the ECU unit checks whether the speed of the car is over 10 KPH or not.
