Corsica V6-3100 3.1L VIN M SFI (1996)
Shift Interlock: Initial Inspection and Diagnostic Overview
Circuit Operation
The Brake Transaxle Shift interlock (BTSI) System is designed to keep the driver from moving the gear selector out of "PARK" without the brake pedal
being depressed. With the brake pedal released, the solenoid is energized and impedes the gear selector from being moved from the "PARK" Position.
When the Brake Pedal is depressed battery voltage is removed from the BTSI Solenoid through the brake Switch from Fuse 9. The Solenoid is
de-energized, allowing the gear selector to move freely from the "PARK" Position.
Troubleshooting Hints - Brake Transaxle Shift Interlock
PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS:
1. Check Fuse 9 by visual inspection
2. Make sure G101 is clean and tight.
3. If Gear Selector does not shift out of "PARK," make sure the linkage is properly adjusted.
