Toyota resumed the operations of 25 vehicle production lines at 12 of its 14 plants in Japan on Wednesday morning, following a suspension caused by a system glitch.
A malfunction in the system that processes orders for vehicle parts occurred Monday and has not been fully resolved, Toyota said, adding a backup system had been activated. The Motomachi plant in the city of Toyota, Aichi Prefecture, is among the 12 plants.
The Toyota group aims to put into operation a total of 28 production lines at all of its 14 domestic plants, including Toyota Motor Kyushu’s Miyata plant in Fukuoka Prefecture, and Daihatsu’s Kyoto plant in Kyoto Prefecture, by Wednesday evening.
According to informed sources, the glitch is believed to have resulted from the updating work of the system that manages ordering of parts.
Toyota and its parts suppliers use this system. Production at all Toyota plants in Japan stopped by Tuesday evening as the automaker became unable to order parts due to the failure.
The Toyota group operates the 14 plants in the Tokyo and the seven prefectures of Iwate, Miyagi, Gifu, Aichi, Mie, Kyoto and Fukuoka.
Operations will be halted Wednesday at Hino’s Koga plant in Ibaraki Prefecture, where the same order management system is used.
