Toyota Motor Corp is to temporarily suspend shipments of 10 vehicle models after supplier Toyota Industries Corp disclosed certification problems concerning some diesel engines.
An investigative committee found irregularities during horsepower-output testing that took measurements based on computer modules running software that ultimately differed from the software that was used for mass production, the Japanese automaker said in a statement yesterday.
The certification issue is the latest blow to beset Toyota, following an announcement by subsidiary Daihatsu Motor Co last month that most of its vehicles were not properly tested for collision safety and that the automaker manipulated the results of tests dating as far back as 1989. As a result, Daihatsu is halting shipments and suspending operations through at least next month.

“To move forward as a group it’s necessary to have a management system that values the voice of workers on the ground,” Toyota chief executive officer Koji Sato said, adding that data fabrication is an issue at the automaker’s subsidiaries as well as communication problems.
Toyota is to halt the production of the affected models in Japan immediately and stop the manufacture of impacted overseas models from today, Sato said, with production to restart on a country-specific basis.
The committee involved in the Toyota Industries issue found irregularities during horsepower-output testing for three engine models.
In total, 10 car models use the engines around the world, the company said.
Those include the Land Cruiser Prado, the Land Cruiser 300, the Fortuner and the Hilux.
The committee had initially been investigating Toyota Industries over certification related to engines used in forklifts. The latest findings came after the probe expanded to construction machinery engines and then diesel engines for cars.
“We weren’t communicating enough with Toyota Motor regarding the test process” after orders increased from 2017, Toyota Industries president Koichi Ito said, adding that he will seek to rebuild communications with the parent company.
The impact of the scandal on earnings is currently unknown, Ito said.
“Going forward, we will be involved in all company-wide activities to help rebuild Toyota Industries and review the situation to thoroughly ensure that safety and quality are the top priorities,” Toyota said in a statement.
The Japanese Ministry of Land, Infrastructure, Transport and Tourism is to start on-site inspections today.
China has claimed a breakthrough in developing homegrown chipmaking equipment, an important step in overcoming US sanctions designed to thwart Beijing’s semiconductor goals. State-linked organizations are advised to use a new laser-based immersion lithography machine with a resolution of 65 nanometers or better, the Chinese Ministry of Industry and Information Technology (MIIT) said in an announcement this month. Although the note does not specify the supplier, the spec marks a significant step up from the previous most advanced indigenous equipment — developed by Shanghai Micro Electronics Equipment Group Co (SMEE, 上海微電子) — which stood at about 90 nanometers. MIIT’s claimed advances last
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has appointed Rose Castanares, executive vice president of TSMC Arizona, as president of the subsidiary, which is responsible for carrying out massive investments by the Taiwanese tech giant in the US state, the company said in a statement yesterday. Castanares will succeed Brian Harrison as president of the Arizona subsidiary on Oct. 1 after the incumbent president steps down from the position with a transfer to the Arizona CEO office to serve as an advisor to TSMC Arizona’s chairman, the statement said. According to TSMC, Harrison is scheduled to retire on Dec. 31. Castanares joined TSMC in
EUROPE ON HOLD: Among a flurry of announcements, Intel said it would postpone new factories in Germany and Poland, but remains committed to its US expansion Intel Corp chief executive officer Pat Gelsinger has landed Amazon.com Inc’s Amazon Web Services (AWS) as a customer for the company’s manufacturing business, potentially bringing work to new plants under construction in the US and boosting his efforts to turn around the embattled chipmaker. Intel and AWS are to coinvest in a custom semiconductor for artificial intelligence computing — what is known as a fabric chip — in a “multiyear, multibillion-dollar framework,” Intel said in a statement on Monday. The work would rely on Intel’s 18A process, an advanced chipmaking technology. Intel shares rose more than 8 percent in late trading after the
FACTORY SHIFT: While Taiwan produces most of the world’s AI servers, firms are under pressure to move manufacturing amid geopolitical tensions Lenovo Group Ltd (聯想) started building artificial intelligence (AI) servers in India’s south, the latest boon for the rapidly growing country’s push to become a high-tech powerhouse. The company yesterday said it has started making the large, powerful computers in Pondicherry, southeastern India, moving beyond products such as laptops and smartphones. The Chinese company would also build out its facilities in the Bangalore region, including a research lab with a focus on AI. Lenovo’s plans mark another win for Indian Prime Minister Narendra Modi, who tries to attract more technology investment into the country. While India’s tense relationship with China has suffered setbacks
