INTRODUCTION

This bulletin announces availability of a new power seat memory control module designed to address customer concerns of the seat memory feature not operating properly. When pressing the buttons to recall one of the last seat positions memorized, the seat (height, backrest position, etc.) may not always return to the correct or exact positions previously selected (or stored in the control unit memory).

PRODUCTION CHANGE INFORMATION

The new power seat memory control module was incorporated into production starting with the following VINs:

Legacy: H*002508
Outback: H*200084

PART INFORMATION

UNIT ASSEMBLY SEAT MEMORY	64122AL00A

SERVICE PROCEDURE/INFORMATION

IMPORTANT: ALWAYS review the vehicle Service history before proceeding to determine if there may have been a prior repair which would have required re-initialization of the power seat control module:

Driver's seat removal
Prior power seat control module replacement
Slide rail or backrest frame removal/replacement.

If any of the above repairs were performed and the seat initialization process was not completed properly, follow the initialization (calibration) procedure provided below or in the Power Seat (SE) section of the applicable Service Manual. When successfully completed, re-check for proper power seat memory operation BEFORE ordering/installing a new control module which may not be necessary.

POWER SEAT CONTROL MODULE INITIALIZATION PROCEDURE

IMPORTANT: For best results, it is strongly recommended to perform this procedure in as quiet an area as possible with the ignition "ON", all doors and windows closed and the engine off (KOEO). The "beep" sound heard at the completion of each step is relatively faint and may be difficult to hear. In addition, the battery should always be fully charged.

STEP 1- Using slide switch (1) , move the seat all the way rearward and hold in that position for approximately 3 seconds after it stops moving. An audible "beep" will be heard.
STEP 2- WITHIN 10 seconds of the "beep" and using slide switch (2), tilt the seat all the way downward and hold it in that position for approximately 3 seconds after it bottoms out. An audible "beep" will be heard.
STEP 3- WITHIN 10 seconds of the "beep" and using slide switch (3), lower the seat all the way downward and hold it in that position for approximately 3 seconds after it bottoms out. An audible "beep" will be heard.
STEP 4- WITHIN 10 seconds of the "beep" and using the slide switch (4), move the backrest all the way forward and hold it in that position for approximately 3 seconds after it stops moving. An audible "beep" will be heard.
STEP 5- WITHIN 10 seconds of the "beep", operate any one of the switches briefly "on" then "off". A rapid series of 3 "beeps" will signify the procedure has completed successfully.

If the 3 "beeps" are not heard when performing STEP 5 indicating successful completion, either:

One or more of the previous steps was not completed
More than 10 seconds elapsed between steps
Battery voltage has dropped below minimum requirements to complete the procedure.

If the condition persists, continue with the remainder of this procedure.

Disconnect the ground terminal from the battery sensor and wait for at least 60 seconds before proceeding further.
Remove the driver's seat assembly following the procedure in the applicable Service Manual to access/replace the control module.

IMPORTANT: The part number and location of the new seat memory control module are unchanged. For this reason, the color of the part number label affixed to the module must be confirmed to differentiate between the old and new parts as shown in the illustration below. The old module label is Blue (inset) while the new version is Brown.

NOTE:

When replacing the module, torque the 2 retaining nuts to 5.9 Nm (4.4 ft. lbs.).
When reinstalling the seat assembly, the 4 retaining bolts must be hand-tightened first then final torqued to 53 Nm (39.1 ft. lbs.) using the sequence shown in the illustration below.

Reconnect the battery ground terminal.
Follow the initialization (calibration) procedure as provided above or in the Power Seat (SE) section of the applicable Service Manual.
When complete, confirm proper power seat memory function.
