Is the toyota computer programmed so that the brake always over-rides the throttle? I have a 2009 Avalon.
Toyota is just, this month, begining to install brake override on the 2010 production line. So, we’ll have to assume that NO Toyotas producted until that time had brake override of the electronic throttle.
The best way to find out is to ask a Toyota dealer or contact Toyota directly. I think that they will be straight with you. Well, Toyota and most dealers.
