The sudden acceleration-related
problems that plagued Toyota's vehicles and which were blamed for
several accidents, injuries and deaths, led to a huge recall campaign, a massive fine and even a Congress inquiry. And it is not over yet. Not only because of the pending lawsuits, but also due to a report from CNN on its Anderson Cooper 360 program that aired on Thursday.
The
news network claims that it has uncovered a 2006 Toyota internal memo
marked “confidential” that described the results of the adaptive cruise
control software in the model bearing the internal code 250L that is the
Lexus LS 460.
According to CNN’s translation of
the original Japanese document, the report stated: "The cruise control
activates by itself at full throttle when the accelerator pedal position
sensor is abnormal." It also suggested that the carmaker would have to
implement "a fail-safe overhaul" for another production model, the 180L,
i.e. the Toyota Tundra.
Michael
Pecht, a mechanical engineering professor and director of the CALCE
Electronics Products and Systems Center at the University of Maryland,
worked as a consultant for the Congress during the investigation.
CNN
cited Pecht saying that “This looks like an example of electronics
causing a car to suddenly accelerate”, and questions why the document
was omitted from those obtained by the Congress, the NHTSA and NASA,
which helped in the investigation.
Toyota responded to CNN’s report – and it wasn’t with the traditional Japanese courtesy… The manufacturer’s statement begins as follows:
"CNN
has irresponsibly aired a grossly inaccurate segment that attempts to
resurrect the discredited, scientifically unproven allegation that there
is a hidden defect in the electronic throttle control system that can
cause unintended acceleration."
Toyota
says that the process described in the document is about a test process
carried out on its vehicles, not a software problem it knew about.
It adds that the translation of the document is inaccurate:
"The
translation of ‘勝手に’m which appears in the document, actually
translates to ‘by itself’ (as it does in the first translation by CNN)
or ‘on its own’… and ‘発進’ correctly translates to ‘starts out’. This
phrase ‘starts out on its own’ is used to refer to the fact that the
adaptive cruise control (ACC) was preparing to resume its pre-set speed.
This is not a reference to sudden unintended acceleration."
Moreover,
Toyota cites the translator hired by CNN who acknowledges that, “I
added these words based on my understanding of the context.”
So to sum it up, CNN claims that
Toyota knew of the unintended acceleration issue as far back as 2006,
while the carmaker responds that CNN mistranslated its documents, which
in fact described a standard testing procedure.
