Step
Check
Yes
No
1
CHECK POOR CONTACT IN CONNECTORS.
Check for poor contact of the connectors
between the airbag control module, curtain air-
bag module RH and the curtain airbag sensor
RH.
Is there poor contact?
Replace the airbag
rear harness along
with body harness.
Go to step 2.
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) Connect the battery ground terminal and
turn the ignition switch to ON.
8) Measure the voltage 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 voltage less than 1 V?
Go to step 4.
Replace the airbag
rear harness along
with body harness.
4
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 5.
5
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.
