The British engineers say the faults may not have been detected by Toyota's own testing procedures, but have found through their own research that not all of Toyota's on-board electronics are properly protected from EMI.
“Thirty years’ empirical evidence overwhelmingly points to (sudden acceleration) being caused by electronic system faults undetectable by inspection or testing,” said UK-based engineering consultant, Mr Keith Armstrong.
Mr Armstrong and his two colleagues, Antony Anderson and Brian Kirk, will travel to the United States today where they will report their findings to National Highway Traffic Safety Administrations (NHTSA) officials.
In the United States, Toyota issued the following statement in response to the findings:
“Toyota engineers have comprehensively tested our ETCS under both normal and abnormal conditions including electromagnetic interference, and we have never found a single case of unintended acceleration due to a defect in the system.”
