Shift Interlock System: Description

The transmission shift interlock system prevents driver from moving gearshift lever from "P" position unless ignition switch is in ON position, and prevents ignition key from being removed until gearshift lever is returned to "P" position. On models equipped with Brake Transmission Shift Interlock (BTSI) solenoid, gearshift lever cannot be moved from "P" position while ignition is on until brake pedal is depressed. This prevents accidental movement of gearshift lever from "P" position while engine is running. BTSI solenoid is located in steering column or center console.
