U.S. Secretary of Transportation Ray Lahood said Wednesday that his department would conduct a 'complete review' electronics on Toyota vehicles in response to customer and lawmaker complaints of unintended acceleration.

Lahood's comments comes ahead of testimony by Toyota Motor Corp. President Akido Toyoda, who is set to testify today before lawmakers on the issue.

The secretary had previously disclosed a probe into electronics was taking place but was prompted into making the renewed statement amid concerns that the current recalls were not adequately resolving all instances of the unintended accelartion.

The Department does not have conclusive evidence but added we will do a full investigation.

We're going to have a complete review on the electronics, he said.

Toyota's Probe

Under questioning by lawmakers yesterday about the adequacy of current recalls to fix all affected cars, Toyota Motor Co. U.S. sales chief James Lentz told Congress that the company has not ruled out electronic malfunctions.

While current recalls have addressed issues of unintended acceleration involving faulty floor mats and sticky pedals, Lentz said the recalls have not totally addressed all issues.

He said the company had commissioned an independent study by an outside consultancy, Exponent, on the issue of electronic throttles in its automobiles and that it had not discovered any issues so far.

He said, however that the initial Exponent report was preliminary and that a full report at a later date would be released publicly.
