TCM CONNECTOR REFERENCE
| CAUTION | Observe the traffic law when driving on public roads. |
- Shift the select lever to "D" range, and then drive the vehicle with changing the gear from 1st to 5th.
- When driving the vehicle at 5th speed of "D" range, set the gear to manual mode and drive the vehicle by downshifting using "-" of the paddle shift switch from 5th --> 4th, 4th --> 3rd, 3rd --> 2nd, and 2nd --> 1st. NOTE: At shifting down, drive the vehicle at least 10 seconds in each speed.
- Shift the select lever to "R" range and drive the vehicle for 2 seconds or more.
PREPARATION FOR LEARNING
- Warm up or cool down the vehicle until the ATF temperature displayed on the Subaru Select Monitor is 60 - 80°C (140 - 176°F).
- 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.
- Select {AT related learning & inspecting mode} in the «Transmission Diagnosis» screen of the Subaru Select Monitor.
- Select {AT learning mode} in the «AT related learning & inspecting mode» screen of the Subaru Select Monitor.
- Follow the messages displayed on the Subaru Select Monitor screen when working.
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. |
- Follow the messages displayed on the Subaru Select Monitor screen when working. NOTE: During "SHIFT control system learning in progress" and "AWD control system learning in progress", AT OIL TEMP light in the combination meter starts blinking at 2 Hz and the learning operation starts. The following message is displayed on the screen when the AT OIL TEMP light in the combination meter goes off. When the learning ended abnormally, AT OIL TEMP light blinks at 4 Hz.
- "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. If the message "AT learning ended abnormally." is displayed, start the "AT learning mode" over from the beginning. MESSAGE CHART Message Main reasons for abnormal termination AT learning ended abnormally. Fault is detected during AT learning. The accelerator pedal is depressed during AT learning. Operation which is not directed is performed during AT learning. Brake pedal not stepped on firmly enough. Electronic parking brake not applied strongly enough Abnormal idle speed increase, etc. For detailed operation procedures, refer to PC application help for Subaru Select Monitor.
DRIVING CHECK
Drive the vehicle to check that there is no malfunction such as shifting shock.
When shifting shock is felt, perform learning again. When reducing of shifting shock is not felt, check that other parts are normal.
