Automatic Transmission/Transaxle: Testing and Inspection

Learning Control

GENERAL DESCRIPTION
Be sure to perform the {Clear Memory 2} only when the following services have been performed. And when the shifting shock is occurred during the total check with vehicle driving, perform the learning with following procedures.
^ Replacement of TCM
^ Replacement of transmission assembly
^ Simultaneous replacement of TCM and transmission assembly
^ Replacement of each clutch
^ Replacement of control valve body

CAUTION: When {Clear Memory 2} is executed, DTC may not be cleared.

PROCEDURE
1. Turn the ignition switch to ON.
2. Turn the air conditioner switch to OFF.
3. Turn the headlight switch to OFF.
4. Turn the rear defogger switch to OFF.
5. Start the engine.
6. Connect the Subaru Select Monitor to the vehicle.
7. Drive the vehicle for 5 - 10 km (3 - 6 mile) to warm up ATF temperature more than 70°C (158°F).
8. While checking that the throttle opening angle on Subaru Select Monitor is within the specified range, shift the gear from 1st ->2nd, 2nd ->3rd, and 3rd ->4th, while driving the vehicle at D range.
Acceleration opening angle: 12.5% ± 2%
9. While checking that the throttle opening angle on Subaru Select Monitor is within the specified range, upshift the gear from 4th ->5th while driving the vehicle at D range.
Acceleration opening angle: 15.5% ± 2%
10. Repeat the steps 8) and 9) until the reducing effect of the shifting shock is felt.
11. If reducing of shifting shock is not felt after 5 cycles, recheck that the learning conditions (throttle opening angle, ATF temperature, etc.) are as specified and recheck that other parts are normal.
