TM-112 < ECU DIAGNOSIS > [5AT: RE5R05A] TCM this happens, switch OFF the ignition switch for 10 seconds. Then switch it ON again to return to the normal ). FAIL-SAFE FUNCTION If any malfunction occurs in a sensor or solenoid, this function controls the A/T to make driving possible. Vehicle Speed Sensor Signals are input from two systems - from vehicle speed sensor A/T (revolution sensor) installed on the A/T Accelerator Pedal Position Sensor If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according Throttle Position Sensor If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according PNP Switch In the unlikely event that a malfunction signal enters the TCM, the position indicator is switched OFF, the Starter Relay The starter relay is switched OFF. (Starter is disabled.) A/T Interlock • If there is an A/T interlock judgment malfunction, the A/T is fixed in 2nd gear to make driving possible. NOTE: • When interlock is detected at the 3rd gear or more, it is locked at the 2nd gear. A/T 1st Engine Braking When there is an A/T first gear engine brake judgment malfunction, the low coast brake solenoid is switched Line Pressure Solenoid The solenoid is switched OFF and the line pressure is set to the maximum hydraulic pressure to make driving Torque Converter Clutch Solenoid The solenoid is switched OFF to release the lock-up. Low Coast Brake Solenoid When a malfunction (electrical or functional) occurs, in order to make driving possible. If the solenoid is ON, Input Clutch Solenoid If a malfunction (electrical or functional) occurs with the solenoid either ON or OFF, the A/T is held in 4th gear Direct Clutch Solenoid If a malfunction (electrical or functional) occurs with the solenoid either ON or OFF, the A/T is held in 4th gear Front Brake Solenoid If a malfunction (electrical or functional) occurs with the solenoid ON, in order to make driving possible.
