Automatic Transaxle (5AT) (Diagnostics): Other Subaru Outback BS

PROCEDURE

CHECK

Check the following items when a problem has occurred.

Note. Use copies of this list for interviewing customers.

Scheme 840

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

7 N.m (0.7 kgf-m, 5.2 ft-lb)

Scheme 841

ATF LEVEL

Make sure that ATF level is the specified amount. Refer to INSPECTION .

Scheme 842

FRONT DIFFERENTIAL OIL LEVEL

Make sure the front differential oil level is the specified amount. Refer to INSPECTION .

Scheme 843

GENERAL TOOL

Scheme 844

Scheme 845

Scheme 846

Scheme 847

Scheme 848

Scheme 849

Scheme 850

Note. Measure after warming up.

1. Shift the select lever to "D" range, and then drive the vehicle with changing the gear from 1st to 5th.
2. 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.
3. Shift the select lever to "R" range and drive the vehicle for 2 seconds or more.

PREPARATION FOR LEARNING

1. Warm up or cool down the vehicle until the ATF temperature displayed on the Subaru Select Monitor is 60 - 80°C (140 - 176°F).
2. 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, etc.

SIMPLE LEARNING

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

1. Select {AT related learning & inspecting mode} in the «Transmission Diagnosis» display 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: For the messages "SHIFT control system learning in progress" and "AWD control system learning in progress", AT OIL TEMP light in the combination meter blinks at a cycle of 2 Hz before learning operation starts. When AT OIL TEMP light in the combination meter goes off, the following message is displayed on the screen. When operation ends abnormally during the learning, AT OIL TEMP light blinks at a cycle of 4 Hz.
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» 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 Main reasons 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 Brake pedal is not fully depressed. Electric parking brake not applied strongly enough Abnormal idle speed increase, etc. For detailed operation procedures, refer to "Subaru Select Monitor" operating information.

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.
