Shift Interlock: Description and Operation
Operation
OPERATION
The Brake Transmission Shifter/Ignition Interlock (BTSI) is engaged whenever the ignition switch is in the LOCK (1) position. An additional electrically
activated feature will prevent shifting out of the PARK position unless the brake pedal is depressed at least one-half inch. A solenoid in the shifter
assembly is energized when the ignition is in the ON position and the brake pedal is depressed. When the key is in the ON position and the brake pedal is
depressed, the shifter is unlocked and will move into any position. The interlock system also prevents the ignition switch from being turned to the LOCK
position, unless the shifter is in the gated PARK position.
The following chart describes the normal operation of the Brake Transmission Shift Interlock (BTSI) system. If the "expected response" differs from the
vehicle's response, then system repair and/or adjustment is necessary.
BTSI Override
In the event of an electrical failure, the vehicle can be shifted out of PARK by using the following procedure.
