Description
The brake transaxle shift interlock (BTSI) system is comprised of the
following components:
• | The shift interlock actuator within the steering column (or under
the console) |
| The actuator is used in order to lock the gear shift lever. |
• | The brake-pedal mounted stoplamp/BTSI switch |
| This switch is used in order to enable/disable the shift interlock actuator. |
| The circuitry establishes the conditions for operation of the BTSI system. |
Operation
The brake transaxle shift interlock (BTSI) is a safety circuit that
prevents the vehicle from accidently shifting out of PARK when the ignition
switch is in RUN. The vehicle is equipped with a shift interlock actuator.
This actuator, when energized, physically blocks the gear shift lever
from moving out of PARK when the ignition switch is in RUN. The shift
actuator de-energizes, allowing the gear shift lever to move, by pressing
the brake pedal.
