System Outline
1. Shift Lock Mechanism
When the brake pedal is depressed with the ignition SW is turned on (Stop light SW on), the shift lock control ECU is
activated and allows the driver to change the shift lever to a position other than P position.
2. Key Interlock Mechanism
When the ignition SW is turned on and the shift lever is at a position other than P position, shift lock control ECU is activated
to flow current to the key interlock solenoid. This inhibits to turn the ignition SW from on to OFF position.
