- Shift Lock Mechanism
If the brake pedal is depressed with the ignition SW set at ON (The stop light SW is on), the shift lock control ECU is activated, allowing the driver to change the shift lever to a position other than the P position.
- Key Interlock Mechanism
When the ignition SW is turned to the ACC or ON position and the shift lever is at a position other than the P position, the shift lock control ECU is activated to flow the current into the key interlock solenoid. This inhibits to turn the ignition SW from the ACC position to the OFF position.
