Monitor Description
WARNING: This page is about a different variant/trim than selected.
Based on the signals from the throttle position sensor, the mass airflow meter and the crankshaft position sensor, the ECM sends a signal to the shift solenoid valve SL to regulate the hydraulic pressure and provide smoother gearshifts. The shift solenoid valve SL responds to the signals from the ECM. The valve controls the lock-up relay valve to perform the torque converter lock-up function. If the ECM detects an open or short circuit of the shift solenoid valve SL, it illuminates the MIL.
