1) How to disconnect:
Holding outer part (A), pull it in the direction of ar-
row.
CAUTION:
When pulling the slide lock or disconnecting
connector, be sure to hold the connector, not
the harness.
2) How to connect:
Holding the connector, push it in securely until a
clicking sound is heard.
CAUTION:
•Outer side (A) move back, and so do not put
your hand on the outer part.
•Be sure to insert the connector in until it is
locked. Then pull it gently to make sure that it is
locked.

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
*7. Seat belt not fastened
*8: Displayed when data other than belt fastened or not fastened, such as breakdowns is input.
*9: Seat belt buckle switch not supported
*10: Passenger’s seat air bag operating state

G: DTC 23 CONNECTOR TO AIRBAG ECU FAILURE
DTC DETECTING CONDITION:
Connection of (AB6), (AB17) and (AB18) to airbag control module is improper.
CAUTION:
Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
Step Check Yes No
1CHECK POOR CONTACTS OF CONNEC-
TORS (AB6), (AB17) AND (AB18).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connectors (AB6), (AB17)
and (AB18) from airbag control module.
Is there rust or damage on the
harness connector and the
control module connector?
Replace the airbag
control module.
Module.> Replace
the body harness
with the airbag
main harness or
replace the body
harness with the
side airbag har-
ness.
Go to step 2.
2CHECK POOR CONTACTS OF CONNEC-
TORS (AB6), (AB17) AND (AB18).
1) Reconnect the connector securely.
2) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Go to step 3.Replace the airbag
control module.
Module.>
3CHECK AIRBAG CONTROL MODULE.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed? Replace the airbag
control module.

5CHECK THE AIRBAG HARNESS.
Measure the voltage between connector (2AB)
in the test harness AB and chassis ground.
Connector & terminal
(2AB) No. 1 — chassis ground:
Is the voltage more than 9 V? Replace the airbag
rear harness RH
with body harness.
Replace the occu-
pant detection har-
ness (seat
harness). If defec-
tive is not
improved, replace
the occupant
detection system
(seat cushion &
frame assembly),
and then the air-
bag control mod-
ule in this order.

P: DTC 31 FRONT SUB SENSOR RH FAILURE
DTC DETECTING CONDITION:
•Front sub sensor harness (RH) circuit is shorted.
•Front sub sensor harness (RH) circuit is open.
•Front sub sensor (RH) is faulty.
•Airbag control module is faulty.
CAUTION:
•Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
•After replacing the airbag module, seat belt pretensioner, roll connector, control module and sen-
sor, reconnect each part and confirm that the warning light operates properly.
