Japan's transport ministry inspected a Toyota Industries Corp. factory in central Japan on Tuesday, a day after the company admitted to rigging engine power data resulting in a partial halt of shipments from major automaker Toyota Motor Corp.

Based on the results, the ministry is expected to determine the severity of administrative punishment it will impose on Toyota Industries, such as an operation correction order and the revocation of certifications needed for mass production.

Toyota Motor said Monday it will stop the shipment of 10 models sold globally as Toyota Industries fabricated data on diesel engines it makes and supplies to the automaker. The affected vehicles include popular models such as the Land Cruiser 300 Series and the Hilux.

Toyota Industries doctored the volume of flow into the fuel injectors in engine output tests in a bid to make the engines' torque, or rotational force at the crankshaft, appear higher than it is, according to a report by a third-party panel.

The data rigging was also found in the testing for all industrial engines Toyota Industries currently produces, and it has stopped shipment of the affected products, the company said.

Toyota Motor Corp. was spun off from Toyota Industries in the late 1930s and the latter remains the one of the largest shareholders in the automaker, holding an 8.82 percent stake as of the end of September 2023.

Speaking at a press conference in Tokyo on Monday, Toyota Industries President Koichi Ito apologized for troubling customers, saying the management is responsible for "failing to discover and rectify" the misconduct that persisted for a long time.
