DESCRIPTION
The ECM controls the solenoid (SLU) valve using a predetermined current, and performs lock-up and flex lock-up control.
The ECM compares the engagement condition of the lock-up clutch with the lock-up schedule in the ECM memory to detect mechanical malfunctions of the solenoid (SLU) valve, transmission valve body assembly and torque converter assembly.
