Automatic Transmission/Transaxle: Testing and Inspection

Learning Control

GENERAL DESCRIPTION
When the following services have been performed, be sure to perform the transmission learning control. Perform the learning control in order of simple learning driving learning.
^ Replacement of TCM
^ Replacement or disassembly of transmission assembly
^ Replacement of control valve body
^ When {Clear Memory 2} is executed

PROCEDURE

PREPARATION FOR LEARNING CONTROL
1) Shift the select lever to "P" range, and turn the ignition switch to ON (engine OFF).
2) Read DTC using Subaru Select Monitor to confirm no DTC is detected.
3) Start the engine.
4) Drive the vehicle until ATF oil temperature displayed by the current data read operation on Subaru Select Monitor reaches 60 - 90°C (140 - 194°F).
5) Lift up the vehicle.

CAUTION: When performing learning control, be sure to keep the lower edge of the tires 30 cm or more above the ground as vehicle vibrates during the work.

6) Shift the select lever to "P" range, and turn the ignition switch to OFF.
7) Fully apply the parking brake.

CAUTION: When performing the transfer clutch learning, fully apply the parking brake to avoid tires from rotating.

SIMPLE LEARNING
1) Turn the ignition switch to ON (engine OFF).
2) With the brake pedal depressed, shift the select lever to "R" range.
3) Perform the {Clear Memory 2}.
4) Without depressing the brake pedal, turn the ignition switch to ACC and wait for 10 seconds.
5) Depress and hold the brake pedal with left foot until step 17).
6) Turn the ignition switch to ON.
7) Select {Normal sampling} on the �Current Data Display & Save� screen of Subaru Select Monitor, and confirm that ATF oil temperature reaches 60 - 90°C (140 - 194°F).
8) Shift the select lever to the "P" range, and wait for 3 seconds or more.
9) Shift the select lever to the "R" range, and wait for 3 seconds or more.
10) Shift the select lever to the "N" range, and wait for 3 seconds or more.
11) Shift the select lever to the "D" range, and wait for 3 seconds or more.
12) Shift the select lever to the "N" range, and wait for 3 seconds or more.
13) Slowly depress the accelerator pedal to full throttle.
14) Slowly release the accelerator pedal to full close.
15) Start the engine, and idle it.
16) Shift the select lever to "D" range.
17) Transmission simple learning starts. AT OIL TEMP light in the combination meter illuminates. (Parking brake mark is displayed on the multi-information display, but it is normal.) If AT OIL TEMP light does not illuminate, repeat the simple learning from step 1) again.
18) Confirm that the AT OIL TEMP light in the combination meter illuminates and that buzzer sounds at 2 Hz, and then release the brake pedal. (After the brake pedal is released, the buzzer will continue to sound for a while and the AT OIL TEMP light will blink.)
19) Confirm that the AT OIL TEMP light in the combination meter illuminates and that buzzer sounds at 2 Hz, and then depress the brake pedal with left foot. (After the brake pedal is depressed, the buzzer will continue to sound for a while and the AT OIL TEMP light will blink.)
20) Make sure that buzzer sounds at 2 Hz, and shift the select lever to "R" range.
21) The simple learning completes normally if the AT OIL TEMP light in the combination meter goes off. If the blinking of the AT OIL TEMP light changes from 2 Hz to 4 Hz, repeat the simple learning from step 1) again.
22) Shift the select lever to "P" range, turn the ignition switch to OFF, and then leave it for 30 minutes or more.
23) Lower the vehicle.

DRIVING LEARNING
1) Start the engine.
2) Connect Subaru Select Monitor to the vehicle, and select {Normal sampling} on the �Current Data Display & Save� screen.
3) Drive the vehicle for 5 - 10 km (3 - 6 miles) to warm up ATF temperature to be 60°C (140°F) or more.
4) Shift the SI-DRIVE selector to "S" mode.
5) While checking that the throttle opening angle on Subaru Select Monitor is within the specified range, shift the gear from 1st 2nd, 2nd 3rd, 3rd -* 4th, and 4th 5th, while driving the vehicle at "D" range.
Acceleration opening angle: 30% or more
6) Repeat the step 5) until the reducing effect of the shifting shock is felt.
7) If reducing of shifting shock is not felt after performing the cycle described in step 5), recheck that the learning conditions (throttle opening angle, ATF temperature, etc.) are as specified, and recheck that other parts are normal.
