SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor and air-flow meter to monitor the engagement condition of the lockup clutch.
Then the ECM compares the engagement condition of the lockup clutch with the lock-up schedule in the ECM memory to detect mechanical trouble of the shift solenoid valve SLU valve body and torque converter clutch.
