System Outline

If the brake pedal is depressed while 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.

If the ignition SW is turned on and the shift lever is in a position other than the P position, the shift lock control ECU is activated to send current to the key interlock solenoid. This prevents the ignition SW from being turned from the ON to OFF position.
