The circuit (10) is inserted between an IC and a microcomputer to prevent mulfunction. The circuit comprises resistors (R1-29), capacitors (C1-12), diodes (D1-6), Zener diodes (ZD1-3), and transistor (Q1-3). If the system is normal, the microprocessor (20) applies the high signal to the base of the transistor (Q3) to turn on through the hybrid tap (HB8). Then the source power (Vcc) grounds between the corrector and the emitter of the turned on transistor to inform the normal state to the driver.
