These posts will apply to to the midsized SUV’s listed below. There will be slight differences between brands and year models.  Year model 2002 mode actuators are different from all other years and so is the procedure. I have not had the opportunity to document one of these yet. If the vehicle has adjustable pedals the accelerator pedal assembly may have to be removed.
