External Controls: BSIA
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
A BSIA system is used on vehicles equipped with an automatic transmission. This system prevents the transmission selector lever from moving out of the PARK position unless the brake pedal is applied. When the BSIA is de-energized, the transmission selector lever is locked in the PARK position. When the brake pedal is applied, the BSIA is energized and the transmission selector lever can be moved out of the PARK position.
