Refer to ROAD TEST .
PREPARATION FOR LEARNING
- Warm up or cool down until the ATF temperature displayed on the Subaru Select Monitor is 40 - 65°C (104 - 149°F).
- After stopping the vehicle, shift the select lever to "P" range.
- Apply the electronic parking brake.
- 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.
- Connect the Subaru Select Monitor to data link connector.
- Turn the ignition switch to ON.
- Turn off all switches causing an electrical load, such as headlights, A/C, seat heater and rear defogger, etc.
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 OFF during work, and do not disconnect the data link connector. |
- Select {Work Support} in the «Transmission Diagnosis» display screen of the Subaru Select Monitor.
- Select {Compulsory learning mode} in the «Work Support» display screen of the Subaru Select Monitor.
- 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.
- When «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» appears during learning, select [OK] and display the DTC list. 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 switch to OFF before operating the select lever. If the message «AT learning ended abnormally.» is displayed, start the "AT learning mode" over from the beginning. Message Main causes for abnormal termination «AT learning ended abnormally.» Fault is detected during AT learning. The accelerator pedal is depressed during AT learning. An unspecified operation was performed during AT learning ATF temperature becomes out of specification during AT learning. Battery voltage is low. Malfunction indicator light illuminates. Electric parking brake not applied strongly enough Brake pedal is not fully depressed. Abnormal idle speed increase, etc. For detailed operation procedures, refer to "PC application help for Subaru Select Monitor".
