The use of EEPROM has enabled the A/T learned value to be retained even after the battery terminals are disconnected. However, the learned value should be initialised if the A/T assembly, the engine assembly, the valve body assembly or the solenoid valves are replaced. The initialization procedure is as below:

1. Shift the selector lever to the P range and turn the ignition switch to the LOCK (OFF) position. Then, connect the MUT-II/III to the diagnosis connector.

2. Initialize the learned value on the initializaion screen.

3. After this initialization, make the system learn the idling in accordance with "Learning procedure for idling in MPI engine" (Refer to GROUP 00 - Precautions before Service ).
