Programming and Relearning

Learning Control

GENERAL DESCRIPTION

^ Follow the messages displayed on the Subaru Select Monitor when working.
^ When the following work is performed, perform learning for the transmission. Replacement of TCM/Replacement or disassembly of transmission assembly/Replacement of control valve body/Performing "Clear Memories 2".

PROCEDURE

PREPARATION FOR LEARNING

1) Warm up or cool down until the ATF temperature displayed on the Subaru Select Monitor is 40 - 65°C (104 - 149°F).
2) After stopping the vehicle, shift the select lever to "P" range.
3) Apply the electronic parking brake.
4) Lift up the vehicle.

CAUTION:
While working, be sure to keep the lower edge of the tires 30 cm or more above the ground as vehicle will vibrate.

5) Connect the Subaru Select Monitor to data link connector.
6) Turn the ignition switch to ON.
7) Turn off all switches causing an electrical load, such as headlights, A/C, seat heater and rear defogger.

NOTE:
Error message is not displayed even when an incorrect mode is set. In this case, the learning may not be performed correctly, retry "AT learning mode" from the beginning.

SIMPLE LEARNING

NOTE:
Simple learning is performed with the vehicle lifted, without actually running the vehicle.

CAUTION:
Do not turn the power of the Subaru Select Monitor to OFF or disconnect the data link connector during the operation.

1) Select {AT related learning & inspecting mode} in the [[Transmission Diagnosis]] screen of the Subaru Select Monitor.
2) Select {AT learning mode} in the [[AT related learning & inspecting mode]] screen of the Subaru Select Monitor.
3) Follow the messages displayed on the Subaru Select Monitor screen when working.

NOTE:
During AT learning in progress, AT OIL TEMP light in the combination meter starts flashing at 2 Hz and the learning operation starts. The following message is displayed on the screen when the AT OIL TEMP light which was flashing at 2 Hz turns off.

4) "AT learning normally ended." is displayed, simple AT learning is completed.

NOTE:
^ If communication error occurs during learning, retry the "AT learning mode" from the beginning.
^ If the message "Execute AT learning again after fixing troubles of the vehicle" is displayed during learning, select [OK] to display the List of Diagnostics Trouble Code. After repairing the locations indicated by the DTC, start the "AT learning mode" over from the beginning.
^ When communication error occurs during learning, select lever does not shift occasionally. If select lever does not shift, turn the ignition to OFF and operate the lever.
^ If the message "AT learning ended abnormally." is displayed, start the "AT learning mode" over from the beginning.





^ For detailed operation procedures, refer to "PC application help for Subaru Select Monitor".

AT OIL TEMP Warning Light Display

OPERATION

The AT OIL TEMP light illuminates or blinks, when the ATF temperature is high and malfunction occurs in CVT.
^ When normal AT OIL TEMP light always illuminates when the ignition switch is ON (engine OFF). Light goes off after two seconds from engine ON.
^ When ATF temperature is high AT OIL TEMP light illuminates when the ATF temperature is abnormally high with engine ON.
^ When malfunction is detected AT OIL TEMP light blinks at 2 Hz when the TCM detects the malfunction of CVT with engine ON. In this case, inspect using "Diagnostic Procedure with Diagnostic Trouble Code (DTC)".
^ When AT learning is not finished AT OIL TEMP light repeats "Blinking at 4 Hz -> Turning OFF" every two seconds, when the AT learning is not finished with engine ON. In this case, perform the "Learning". (During AT learning, the light blinks at 2 Hz or illuminates.)





IF the AT OIL TEMP light does not illuminate, or illumination patterns are not as above, check the AT OIL TEMP light circuit.

INSPECTION

DIAGNOSIS:
^ AT OIL TEMP light circuit is open or shorted.
^ Combination meter malfunction
^ TCM is in special control mode.
^ AT learning is not finished.

TROUBLE SYMPTOM:
^ When the ignition switch is turned to ON, the AT OIL TEMP light does not illuminate.
^ AT OIL TEMP light remains lit after engine start.
