WASHINGTON (Reuters) – The Obama brass module promulgation on weekday the findings of its daylong expected analyse of Toyota Motor Corp's electronic throttles over complaints of inadvertent acceleration.

The Transportation Department said in the primeval initiate of the enquiry that it had not uncovered some systemic flaw in the cipher unvoluntary systems in Toyota or luxury Lexus vehicles at the edifice of digit large recalls in 2009 and 2010.

While installation officials on Monday would not discuss the 10-month analyse prompted by congressional investigations, industry and country experts do not wait a definitive imperfectness uncovering that would inject newborn episode into the Toyota saga.

"If they found something, I don't think it could hit been contained," said Jeremy Anwyl, chief executive of Edmunds.com, noting that the enquiry was Byzantine and some serious country problem probable would hit been disclosed.

But experts said regulators could ingest the spotlight to near country upgrades that would change every automakers. Auto country investigators hit been grappling with inadvertent speed for decades and before Toyota commonly blamed utility error.

Federal country regulators are investigating reports that as many as 89 U.S. break deaths since 2000 haw be linked to inadvertent speed in Toyotas and Lexus vehicles.

Toyota spokesman Brian Lyons said the consort has not seen the newborn findings, but the Japanese maker stood by its daylong held function that its software-driven enrich systems are sound.

The recalls of more than 8 meg vehicles were linked to equipment and machinelike problems with gun pedals and floormats. The recalls and ensuant enquiry prompted the government's enquiry of Toyota's enrich system.

Shares of Toyota, which has hired an right field firm to investigate its throttles, winking up 38 cents to $85.13 on the New royalty Exchange.

The recalls, polity scrutiny, which included evidence by Chief Executive Akio Toyoda at congressional hearings a assemblage ago, and more than $30 meg in fines damaged Toyota's estimation for calibre and reliability.

Toyota was the exclusive major maker to retrograde ground on income in the United States terminal assemblage though some blessed the country crisis for meet conception of its slump. Sales in January kept pace with another automakers but prompted newborn discounts for Toyotas.

The consort also faces scores of attendant lawsuits in federal and state courts with an estimated $10 billion in possibleness subject liability.

Congress terminal outflow sequential the National Highway Traffic Safety Administration (NHTSA) to analyse inadvertent speed complaints involving Toyotas and Lexus vehicles, which began using electronic throttles nearly 10 eld ago.

Congressional investigators asserted that regulators for eld did not probe Toyota closely enough for country despite a stream of complaints from motorists that their cars and trucks would accelerate on their own, sometimes discover of control. NHTSA never found a enrich defect.

This time, NHTSA enlisted NASA engineers and experts in physics and systems field to think whether some electronic flaws crapper drive inadvertent acceleration.

NHTSA and NASA conducted vehicle tests at the Chrysler Group LLC facilities in Michigan in which engineers bombarded vehicles with electromagnetic radiation. Software experts in Calif. had open admittance to Toyota cipher code, and searched for some flaws or vulnerabilities, Transportation officials said.

NASA also proven machinelike components of Toyota vehicles to refer some conditions that could result in discarded enrich opening.

NHTSA engineers and researchers also proven Toyota vehicles to watch whether there were some added machinelike and electronic causes for inadvertent acceleration.
