Toyota Corolla Repair Manual: Circuit description

The shift solenoid valve sl is turned on and off by signals from the ecm in order to control the hydraulic pressure operation, the lockup relay valve, which then the controls operation of the lockup clutch.

Fail safe function: if the ecm detects a malfunction, it turns the shift solenoid valve sl off.

Monitor description

Monitor description

Based on the signals from the throttle position sensor, the airflow meter and the crankshaft position sensor, the ecm sends a signal to the sl solenoid valve to regulate the hydraulic pressure and provide smoother gearshifts. The shiftsolenoid valve sl responds to commands from the ecm. The valve controls the lockup relay valve to perform the torqueconverter lockup function. If the ecm detects an open or short circuit for shiftsolenoid sl, it will illuminate the mil.
