The U.S. House Energy and Commerce Committee is still pouring over Toyota's unintended acceleration issues, and right now the group is looking into older braking systems. Automotive News reports that the committee was told by investigators that an investigation of a 2005 Toyota Camry showed that some older model Toyotas were equipped with brake override systems (although not all newer models have such equipment). Toyota, as you may recall, has promised to equip all 2011 model year vehicles with a brake override system.

The Japanese automaker has also been asked by the committee to detail the work being performed by research firm Exponent Inc. relative to Toyota's unintended acceleration issues. Exponent has said that it hasn't found any electronics issues that would lead to unwanted acceleration issues. For his part, Committee Chairman Henry Waxman has told reporters in a letter that Exponent "has not been fully cooperative with the committee's requests."

Toyota is reportedly being given until July 6 to contact the House committee, and documents must be provided by July 12. Toyota spokesman Mike Michels has informed AN that the company will cooperate with requests from the committee.
