A: OPERATION
1. READ DIAGNOSTIC TROUBLE CODE (DTC)
When malfunction of the airbag system and the occupant detection system occur, the DTC stored in airbag
control module will be read out.
Refer to the DTC readout of the airbag system (diagnosis).
NOTE:
•For details concerning operation procedure, refer to the “SUBARU SELECT MONITOR OPERATION
MANUAL”.
•For details concerning DTCs, refer to the “List of Diagnostic Trouble Code (Airbag system, Occupant de-
tection system).”
2. DISPLAY OF STATUS INFORMATION
Check the operating condition of each sensor in the event of malfunction in seat belt buckle switch and seat
position sensor, or when the seat belt buckle switch and seat position sensor has been replaced.
1) On the «Main Menu» display screen, select the {Each System Check} and press the [YES] key.
2) On the «System Selection Menu» display screen, select the {Airbag System} and press the [YES] key.
3) On the «Airbag System» display screen, select the {Status Data} and press the [YES] key.
The following table is for support data.
*1: The seat position is forward.
*2: The seat position is rearward.
*3: Displayed when data other than before and behind the seat, such as the breakdown etc, is input.
*4: Displayed when it is initial.
*5: Seat position sensor not supported
*6. Seat belt fastened

3. CLEAR MEMORY MODE
Clear the DTC stored in the airbag control module
after repairing the airbag system and occupant de-
tection system. (After the breakdown is recovered,
the breakdown code for completed recoveries are
read out when the next breakdown occurs if the
memory clear work is not performed.)
1) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.

MANUAL”.
4. SYSTEM CALIBRATION (REZEROING)
NOTE:
When replacing the occupant detection system, or
removing and disassembling the passenger’s seat,
always perform the system calibration after install-
ing a seat in the vehicle.
CAUTION:
When the trouble occurs in the system during
calibration process, “Occupant detection cali-
bration failure” is detected in the DTC 2A of the
airbag system and the airbag warning light
lights. In this case, after turning the ignition
switch to OFF once, redo the system calibration
(Rezeroing), or after clearing the cause of the
failure, perform the system calibration again.
1) Park empty vehicle on a level surface.
2) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
3) On the «System Selection Menu» display
screen, select the {Occupant Detection System}
and press the [YES] key.
4) On the Occupant Detection System display
screen, select the {Zero Point Adjustment} and
press the [YES] key.
5) “See service manual. And check vehicle condi-
tion for successfully completing the rezeroing.” is
displayed. Check the following to adjust the condi-
tion of the vehicle.
•Adjust the seat backrest to be vertical. (Press the
power seat switch to put the seat in a position
where it will not move.)
•Adjust the seat sliding position to all the way
back. (Press the power seat switch to put the seat
in a position where it will not move.)
•Do not place anything on the top of the seat
cushion.
•Sit on the seat cushion to smooth the seat sur-
face.
•Check that the passenger’s seat belt is not in-
serted into the buckle, not tense or not stuck.
•Check that ambient temperature is in a range
from 0 to 40°C.
6) When the «Re-zeroing Adjust the passenger
seat to the condition shown in service manual» is
displayed, slide the passenger seat all the way to
the back, check that the backrest is adjusted to all
the way up, and press the [YES] key.
7) When the «Re-zeroing Unbelt the Passenger
seatbelt Continue: YES, Quit: NO» is displayed,
make sure the passenger’s seatbelt is disconnect-
ed from the buckle and press the [YES] key.
8) When the «Re-zeroing Empty the passenger
seat Continue: YES, Quit: NO» is displayed, make
sure that the passenger’s seat is empty, air bag
OFF indicator illuminates and air bag ON indicator
does not illuminate, and press the [YES] key.
NOTE:
•After pressing the [YES] key, «Now processing
.... Wait for a while. Do not touch or give impact to
vehicle and seat» is displayed. Do not touch or rock
