Troubleshooting Hints - Brake Transaxle Shift Interlock

1. The shift lever should lock in Park with the Ignition Switch in the Run position and the brake pedal in the rest position. If the shift lever can be moved from the Park position, with the Ignition Switch in the Run position and without depressing the brake pedal, check turn signal operation. If the turn signals do not operate correctly, check TURN B/U Fuse 16 to see if it is open (the turn signal flasher is on the same circuit as BTSI). If the fuse is open, find and repair source of overload, then replace fuse. If the fuse is good (turn signals operate correctly), continue with Diagnostics.
2. With the Ignition Switch in the Off position, the shift lever should be able to be moved from the Park position without applying the brake. If not, the problem may be with the Steering Column Shift Lever Actuator (W/ Column Shift A/T) or Park Pawl Actuator (W/ Floor Shift A/T), or the shift linkage itself. If the shift linkage is binding, refer to Computers and Control Systems. Powertrain Management If the shift linkage does not appear to be binding, continue with BTSI Diagnostics.
3. If the Park/Neutral Position And Backup Lamp Switch needs adjustment or replacement, Refer to Computers and Control Systems. Powertrain Management
4. To Remove, disconnect, or adjust the Steering Column Shift Lever Actuator (W/ Column Shift A/T) or Park Pawl Actuator (W/ Floor Shift A/T) assembly.
