AA:DTC 46 SIDE AIRBAG LH FAILURE
DTC DETECTING CONDITION:
•Side airbag harness (LH) is shorted to power supply.
•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.
•When inspecting the airbag main harness, disconnect the airbag module connectors of driver's

Step Check Yes No
1CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module, side airbag
module LH and the side airbag sensor LH.
Is there poor contact? Replace the airbag
rear harness LH
with the body har-
ness.
Go to step 2.
2CHECK SIDE AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB20) from
(AB19), and connect the connector (1F) in test
harness F to connector (AB19).
3) Connect the airbag resistor to the connec-
tor (3F) of test harness F.
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 side
airbag module
(LH). 7, Front Seat.>
Go to step 3.
3CHECK AIRBAG REAR HARNESS LH (SIDE
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 (AB31) from cur-
tain airbag module (LH).
4) Disconnect the airbag resistor from test
harness.
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
(3U) in the test harness U and chassis ground.
Connector & terminal
(3U) No. 12 (+) — Chassis ground (–):
(3U) No. 10 (+) — Chassis ground (–):
Is the voltage less than 1 V? Go to step 4.Replace the airbag
rear harness LH
with the body har-
ness.
4CHECK 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.
Airbag Control
Module.>
Go to step 5.
5CHECK ANY OTHER DTC ON DISPLAY.Is any other DTC displayed? Check DTC using
“List of Diagnostic
Tr o u b l e C o d e
(DTC)”. AB(diag)-45, List
of Diagnostic Trou-
ble Code (DTC).>
