Stay tuned and check back because TOYOTA'S CORPORATE HANDBOOK will be updated as other examples are found.
TOYOTA'S CORPORATE HANDBOOK seems universal.
Please note the chapters don't necessarily occur in a predictable order.
Sadly, it is not entirely unexpected when you look at the trouble that owners had in convincing franchised dealers and Toyota that their new Auris HSDs were draining the 12V batteries in 48 hours.
You have a ScanGauge that should be able to read at least part of any DTC thrown?
OTOH if the car is behaving in a way that the engineers had not anticipated then it is possible that there will not be DTC to point directly at an SUA problem.
The Toyota documents she reviewed proved so troubling that Benjamison turned the documents – many marked "secret" and "confidential" – over to Senator Charles Grassley (R-IA). Benjaminson went public because lives were at stake and "the corporate PR megaphone has completely drowned out the victims."
An email written by Hiroshi Hagiwara, a Toyota vice president in Washington, D.C., and sent to executives in Japan a month before the [U.S. Congressional] hearings hints at the turmoil beneath the surface. Hagiwara and Chris Tinto, a V.P. for technical and regulatory affairs and safety, had been talking about the U.S. investigation and an earlier one in Europe that also involved unintended acceleration (UA).
"Tinto is extremely pessimistic," Hawiwara wrote, "and is saying (public hearings, someone will go to jail, I can't completely take care of the pedal problem, etc.)." Tinto's primary concern (according to Hagiwara): "For NHTSA, we said that our investigations in Europe found that the pedal return is a little slow at a slightly open position, and that there were no accidents, but this is not true. Last year's situation in Europe (many reports of sticking pedals and accidents, and a TI TS0-161 was filed on October 1, 2009) was not reported to NHTSA." That failure", Tinto said, "may be a violation of the TREAD ACT" – the federal law that requires car manufacturers that conduct recalls in foreign countries to report these to U.S. regulators.
Still speaking of Tinto, who worked for NHTSA in the 1990s before he was hired away by Toyota, Hagiwara continued: "He appears to question how Toyota has grasped and handled the overall UA problem (mat, accelerator pedal, ECU [electronic control unit], and electronic throttle systems, etc.)."

Behind the scenes, Toyota played hardball with critics. A public relations manager named Masami Doi had spelled out the approach in a December email. "There are at most around 10 people who are the sources of negative tone communications. If they can be suppressed, I think we will be able to manage it somehow. Like you said, let's go with an intention of destroying each individual person's ability to oppose us, one by one…."
