PURPOSE: A self diagnosing method of an inverter driver is provided to grasp on a wrong assembling of a PWM signal wire easily within a short time. CONSTITUTION: A self diagnosing method of an inverter driver comprises the following steps: a microcomputer (MICOM) transmits a PWM signal to the inverter driver (S10); the MICOM receives a feedback signal about the PWM signal from the inverter driver after transmitting the PWM signal (S20); and the MICOM determines whether a PWM signal wire is assembled wrongly or not from the feedback signal (S30). [Reference numerals] (AA) Start; (BB) End; (S10) Transmit a PWM signal to the inverter driver; (S20) Transmit a feedback signal about the PWM signal from the inverter driver; (S30) Determine whether a PWM signal wire is assembled wrongly or not from the feedback signal |
