DEVICE HAVING DARK CURRENT REDUCING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a multiplex transmission system having the dark current reducing function capable of effectively reducing a dark current when reducing the dark current by intermittently carrying an electric current. SOLUTION: This device is provided with a transistor TR1 for supplying electric power to a door lock switch 12 of an ECU 1 and a CPU 1 for intermittently operating and controlling electric power supply of the transistor TR1, and the CPU 1 operates and controls the transistor TR1 in a different intermittent period according to a different time zone.
