Toyota is halting production for at least a day at all 14 of its Japanese plants due to a computer problem at a supplier that may be a cyberattack.

The supplier, Kojima Industries Corp., makes air-conditioning, steering wheel parts and other components for the automaker. The company detected an error in its computer server system that disrupted communication with Toyota and disabled its production tracking system.

"This has never happened before," Kojima spokesman Tomohiro Takayama told the Associated Press. "We are not sure yet if it is a cyberattack, but we suspect it might be one."

Toyota officials said the company didn't know how long the disruption might last.
