AIRBAG SYSTEM (DIAGNOSTICS)
2
CHECK CURTAIN AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 20 sec-
onds or more.
2) Disconnect the connector (AB33), and con-
nect the connector (1N) in test harness N to
connector (AB33).
3) Connect the airbag resistor to the connector
(2N) of test harness N.
4) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Replace the cur-
tain airbag module
(RH). <Ref. to AB-
18, Curtain Airbag
Module.>
Go to step 3.
3
CHECK AIRBAG REAR HARNESS (CUR-
TAIN AIRBAG MODULE HARNESS RH).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 20 sec-
onds or more.
2) Disconnect the connector (AB26) from seat
belt pretensioner (RH).
3) Disconnect connector (AB24) from side air-
bag module (RH).
4) Disconnect the airbag resistor from test har-
ness N.
5) Disconnect the connectors (AB6, AB17,
AB18) from airbag control module.
6) Connect the test harness AG connector
(1AG) to the connectors (AB6, AB17, AB18).
7) Measure the resistance between connector
(6AG) in the test harness AG and connector
(2N) in the test harness N.
Connector & terminal
(6AG) No. 6 — (2N) No. 1:
(6AG) No. 8 — (2N) No. 2:
Is the resistance less than 10
:? Go to step 4.
Replace the airbag
rear harness along
with body harness.
4
CHECK AIRBAG REAR HARNESS (CUR-
TAIN AIRBAG MODULE HARNESS RH).
Measure the resistance between connector
(6AG) terminals in the test harness AG.
Connector & terminal
(6AG) No. 6 — (6AG) No. 8:
Is the resistance 1 M
: or
more?
Go to step 5.
Replace the airbag
rear harness along
with body harness.
5
CHECK AIRBAG REAR HARNESS (CUR-
TAIN AIRBAG MODULE HARNESS RH).
Measure the resistance between connector
(6AG) in the test harness AG and chassis
ground.
Connector & terminal
(6AG) No. 6 — Chassis ground:
(6AG) No. 8 — Chassis ground:
Is the resistance 1 M
: or
more?
Go to step 6.
Replace the airbag
rear harness along
with body harness.
6
CHECK AIRBAG CONTROL MODULE.
1) Connect all connectors.
2) Clear the memory.
3) Perform the Inspection Mode.
4) Read the DTC.
Is the same DTC displayed?
Replace the airbag
control module.
<Ref. to AB-20,
Airbag Control
Module.>
Go to step 7.
7
CHECK FOR ANY OTHER DTC ON DISPLAY. Is any other DTC displayed?
Check DTC using
“List of Diagnostic
Trouble Code
(DTC)”. <Ref. to
AB(diag)-38, List
of Diagnostic Trou-
ble Code (DTC).>
Finish the diagno-
sis.
