#Denso

Toyota Motor Corp. says it had reached an agreement to consolidate all of its core electronics component operations within Denso. The move should allow Toyota to free up resources to compete more effectively in the new vehicle technology field.

Japan’s largest automaker noted it still has to discuss the logistics of transferring production of parts produced at its Hirose plant, near Toyota’s global headquarters, before the end of next year. But Denso, the company’s largest supplier, has already agreed to the core concept of the deal. By 2022, Denso will have taken over the mass production of all electronics components used in Toyota’s vehicles.

The fire-risk blower motor resistor harness has been recalled in the Hummer H3 and owners will start receiving repairs once parts become available. Owners of the Pontiac Solstice and Saturn Sky should be able to use the updated parts as well but will have to pay out of pocket as General Motors has not recalled them at this time. The Chevrolet Colorado and GMC Canyon also use a similar design and pose a similar fire risk but are slightly different than the recalled part due to having one less blower speed.

Hummer owners will most likely wait a few months minimum for the updated parts to get to their dealers to perform their free recall repairs. Colorado and Canyon owners may be waiting much longer — if they are recalled at all. The only silver lining for the Colorado and Canyon is that they use a similar resistor to the Toyota Tacoma and share a connector. The Tacoma also suffered from blower motor resistor issues and received updated parts along with a Technical Service Bulletin in 2011.

Toyota unveiled its plans Wednesday to trial a new hybrid system using silicon carbide power semiconductors that could find its way into hybrids and EVs.

Looking to wring out more fuel efficiency in its hybrids, Toyota has developed a silicon-carbide wafer semiconductor that could boost efficiency up to 10 percent.

Denso, the automotive electronics supplier with close ties to Toyota, has signed an agreement to buy $25.4 million worth of stock in the Sharp consumer electronics company. According to Automotive News, Denso says that the goal is to create new technologies that “improve the comfort, safety and convenience of vehicles by integrating vehicle technologies with home electronic technologies.”

It was the early 2010, the Toyota witch hunt was in full swing. While Toyota executives were burnt at the stake grilled on the Hill, Denso’s U.S. offices were raided by the FBI. Denso is a major automotive parts supplier, and a member of the Toyota family. The raid was part of an on-going investigation into alleged anti-trust violations. Or so they said.

After the NHTSA, NASA and the National Academy of Sciences could not find a ghost in the machine, the Department of Justice also cleared out its case file. For a fee.

Sajeev,

My ’99 Accord 5speed with 200k on the clock needs a new gas tank. The fuel pump is inside the gas tank. Should I get a new fuel pump with that gas tank? Changing the tank will cost about $600; including a fuel pump will add $300. I’m planning to keep this car another year and a half to two years, at which point it will have about 230k.

You thought the strikes that affected Honda and Toyota in China are over, and both are happily churning out cars again? That makes two of us. But we are mistaken.

Update: To see all of TTAC’s related articles on the subject of Toyota gas pedals, go here:

In yesterday’s post , we offered a bounty for anyone to open up both the CTS (bottom) and Denso (top) Toyota gas pedal assemblies. No one took us up, and no one anywhere else has done it, so we took it upon ourselves . Here they are, both e-pedal assemblies taken apart and examined, in our quest to understand if and what the significant differences are, and how Toyota’s possible “shim” fix would work. On initial observation, it appears that the CTS may be perceived as being the more solidly engineered/built unit, in that the pedal pivots on a traditional and solid steel axle whose bearings are brass or bronze sleeves. The Denso’s whole pivot and bearing surfaces are relatively flimsy-feeling plastic. But that can be deceptive, and we’re not qualified to judge properly if it is indeed inferior or superior. So the question that goes beyond the analysis of these e-pedals is this: are these units really the full source of the problem, or are they scape goats for an electronics and/or software glitch? Pictures and tear down examination and analysis follows:

Update #2: It’s clear to me now that the CTS unit I took apart already had the side cover plates (sheet metal) removed before I examined it. One can see where they fit, and are obviously intended to protect the exposed axle pivot and bushing seen above and below:

Automotive News [sub] reports that supplier giant Denso, which is 23 percent owned by Toyota, will launch a competitor to Ford’s Sync system. The system, named Blue Harmony, will provide music, directions, e-mail, Internet radio, news headlines and other driver distractions through a touchscreen on the center of the instrument panel, according to Denso sources. The system will use Denso apps to bring Pandora internet radio, Facebook, Flickr and other web-based services to the Blue Harmony platform.
