Diagnostic Chart with Trouble Code
AIRBAG SYSTEM (DIAGNOSTICS)
AW:DTC BB ROLL OVER:FIRING OUTPUT
This DTC is indicated when the curtain airbag module and the seat belt pretensioner are deployed.
Once this DTC is displayed, the memory cannot be cleared. Replace the following parts.
• Airbag control module<Ref. to AB-19, Airbag Control Module.>
• Curtain airbag module (Operating side) <Ref. to AB-18, Curtain Airbag Module.>
• Curtain airbag sensor (Operating side) <Ref. to AB-21, Curtain Airbag Sensor.>
• Front outer seat belt with pretensioner (operating side) <Ref. to SB-10, Front Seat Belt.>
Step Check Yes No
1 CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module, curtain air-
bag module LH and the curtain airbag sensor LH.
Is there poor contact? Replace the airbag
rear harness LH
along with the 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 more than 20
seconds.
2) Disconnect the connector (AB31) from cur-
tain airbag module (LH), and connect the con-
nector (1N) in test harness N to connector
(AB31).
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
(LH). <Ref. to AB-
18, Curtain Airbag
Module.> Go to step
3
.
3 CHECK AIRBAG REAR HARNESS LH (CUR-
TAIN AIRBAG MODULE HARNESS LH).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB21) from seat
belt pretensioner (LH).
3) Disconnect the connector (AB19) from side
airbag module (LH).
4) Disconnect the airbag resistor from test har-
ness F.
5) Disconnect the connector (AB17) from air-
bag control module.
6) Connect the connector (1U) in the test har-
ness U to connector (AB17).
7) Connect the battery ground terminal and
turn the ignition switch to ON.
8) Measure the voltage between connector
(5U) in the test harness U and chassis ground.
Connector & terminal
(5U) No. 1 (+) — Chassis ground (–):
(5U) No. 3 (+) — Chassis ground (–):
Is the voltage less than 1 V? Go to step 4 . Replace the airbag
rear harness LH
along with the body
harness.
4 CHECK 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.
<Ref. to AB-19,
Airbag Control
Module.> Go to step 5 .
5 CHECK ANY OTHER DTC ON DISPLAY.
Is any other DTC displayed? Check DTC using
“List of Diagnostic
Trouble Code
(DTC)”. <Ref. to
AB(diag)-47, List
of Diagnostic Trou-
ble Code (DTC).> Finish the diagno-
sis.
