Brake/Transmission Shift Interlock Mechanism - Description

DESCRIPTION

" The Brake Transmission Shift Interlock (BTSI) system prevents the driver from shifting out of Park unless the service brake pedal is actuated. This feature is intended to prevent unintended acceleration caused by pedal misapplication. The BTSI system is a ""Power to Release"" shift mechanism. The system is mechanically locked in Park until power is applied to the solenoid contained within the shifter. No brake interlock adjustment is required. In the event of a solenoid problem or power loss, the shifter cannot be moved from Park unless a manual override is actuated. A BTSI override mechanism is provided with this shifter to allow the vehicle to be shifted out of PARK in the event of an electrical failure.
