Lentz also testified that on Monday night Toyota's engineers had replicated the electronic problem demonstrated to ABC News by Dr. Gilbert – he said they were able to cause a short circuit without triggering an error code.
"Toyota was able to produce the same conditions without triggering an error, is that correct?" asked Rep. Diana DeGette, D.-Colo.
"Yes," answered Lentz.
"When was that done?" asked Rep. DeGette.
"In the wee hours of the night," answered Lentz.
DeGette asked if Lentz wanted to amend his opening statement, in which he said Toyota had found no electronic issues after extensive testing. Lentz said he did not, and also tesitifed that Exponent, which conducted the tests for Toyota, was able to replicate the same phenomenon described by Gilbert in a non-Toyota vehicle.
In response to a question from Rep. Mike Doyle, D.-Pa., about replicating Gilbert's research, Lentz said he was "not sure about his testing paradigm," but said Toyota welcomed "anyone that can find any issues with our electronics."
"If there is a problem, we want to find it, and we want to fix it," said Lentz.
"I just think that before you leave Washington, you ought to get this guy's phone number," said Doyle.
