If the TCM detects a malfunction, it turns shift solenoid valve SL off.
MONITOR DESCRIPTION
Based on the signals from the throttle position sensor, the air flow meter and the crankshaft position sensor, the TCM sends a signal to shift solenoid
valve SL to regulate the hydraulic pressure and provide smoother torque converter clutch engagement. Shift solenoid valve SL responds to
commands from the TCM. The valve controls the lock-up relay valve to perform the torque-converter lock-up function. If the TCM detects an open
or short circuit for shift solenoid valve SL, it will illuminate the MIL.
