Abstract: PURPOSE: An error code eliminating method of an engine control unit for a vehicle is provided to prevent errors in repairing by restricting the unnecessary replacement of the sensor, and to cut down replacement cost of parts from repair errors. CONSTITUTION: An engine control unit memorizes the error code in generating instant errors in an engine or vehicle control sensor(110,120). An ignition key is turned on(130), and the normality of the sensor is detected(140). The number of predetermined drive cycle is detected in deciding the normality of the sensor(150). The error code is eliminated from the engine control unit in case of the number of the drive cycle to be more than the reference number(160). The error code remains in the engine control unit in wrong operation of the sensor or if the number of drive cycle is less than the reference number(170). Replacement of normal parts is prevented with automatically erasing the error code in operating the sensor normally.

Abstract: PURPOSE: A method for preventing discharge of a battery is provided to prevent the rapid discharge of the battery by increasing the rotating speed of an engine according to a battery voltage. CONSTITUTION: A running state of an engine is checked(S11). A running time of the engine is checked if the engine is in the running state(S12).
