Toyota Scion tC 2005 Wiring Diagram page 182

System Outline
When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 6 of the shift lock control
ECU. When the ignition SW is turned to ON position, the current from the ECU–IG fuse flows to TERMINAL 1 of the shift lock
control ECU.
1. 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.
2. Key Interlock Mechanism
With the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12
of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock lever
disengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.
