Brake Shift Interlock System
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The brake shift interlock system prevents shifting from PARK unless the brake pedal is depressed. The brake shift interlock system consists of a brake shift interlock actuator mounted at the base of the steering column tube. If the ignition switch is in the RUN position, the brake shift interlock actuator is continually on unless the brake pedal is depressed.
