A Toyota spokeswoman declined to comment on the plans. Japan's top automaker has halted production at its three plants in Thailand, its Southeast Asia production hub, since Oct. 10 after flooding affected suppliers, forcing it to reduce production domestically from Oct. 24, with output currently at 70 to 80 percent of planned levels. Toyota aims to secure alternative parts supplies by the end of this year and boost output back to originally planned levels at the start of 2012, the source said. The source added that Toyota was also looking at how it might be able to restore production at overseas plants at about the same pace as its recovery in Japan. The plan is in line with analysts' expectations of a relatively swift restoration of production after Toyota said the disruption would not be as severe as the March earthquake and tsunami in Japan. "Our view was that it would take 1.5-2 months to resolve supply chain problems caused by flooding in Thailand," Bank of America Merrill Lynch auto analyst Takaki Nakanishi wrote in a research note. "Our impression was that the company would make back much of the production lost in October-December before the end of the business year (on March 31)." Toyota has said the supply of about 100 parts has been disrupted by the Thai floods, primary resin, casting and electronic parts. Nomura Securities analyst Masataka Kunugimoto said he was assuming the floods would cut output by a total of 250,000 vehicles in the year to March. Expectations of a relatively quick resolution to Toyota's supply problems leave just Honda Motor Co struggling to get its footing back. Honda's car factory in the industrial estate in Ayutthaya is under water and the company has said it could take until the end of the business year to restart production there. Separately on Wednesday, Toyota announced a recall of a combined 550,000 Toyota and Lexus vehicles globally, primarily in North America, to replace the crankshaft pulley on their engines. No accidents were reported from the defect. Shares of Toyota ended up 1.6 percent at 2,542 yen, roughly in line with the Tokyo's TOPIX index.
