When the engine control module judges from each signal that lock-up operation conditions have been met, current flows from TERMINAL SL of

lock-up solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL BK of the engine control
module. The engine control module operates and continuous to the lock-up solenoid is cut.
