DESCRIPTION
Based on the signal received by the shift solenoid valve SL, the ECM uses the shift solenoid valve SLU to control the lock-up clutch pressure.
If there is an open or short in the shift solenoid valve SL circuit, the ECM stops sending current to the defective shift solenoid valve.

MONITOR DESCRIPTION
These DTCs indicate an open or short in the shift solenoid valve SL circuit. If there is an open or short in the shift solenoid valve SL circuit, the ECM detects the malfunction, illuminates the MIL and stores a DTC.
