Continuously Variable Transmission (Diagnostics): Other Subaru Forester SJ

PROCEDURE

CHECK

Check the following items when a problem has occurred.

Note. Use copies of this list for interviewing customers.

Scheme 941

SUPPLEMENTAL RESTRAINT SYSTEM "AIRBAG"

The airbag system wiring harness is routed near the TCM.

MEASUREMENT

When measuring the voltage and resistance of the ECM, TCM or each sensor, use a tapered pin with a diameter of less than 0.64 mm (0.025 in) in order to avoid poor contact. Do not insert a pin of more than 0.65 mm (0.026 in) diameter.

BATTERY

Measure the battery voltage and specific gravity of the electrolyte.

Standard voltage: 12 V or more

Specific gravity: 1.260 or more

TRANSMISSION GROUND

Make sure that the ground terminal bolt is tightened securely.

Tightening torque

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. Fully apply the 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, etc.
8. Set SI-DRIVE to I mode. (Vehicles with SI drive)

SIMPLE LEARNING

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

1. Select {Work Support} in the «Transmission Diagnosis» display screen of the Subaru Select Monitor.
2. Select {Compulsory learning mode} in the «Work Support» display 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. 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. Parking brake not applied strongly enough. Brake pedal is not fully depressed. Abnormal idle speed increase, etc. For detailed operation procedures, refer to "Subaru Select Monitor operation manual".
