CHECK AIRBAG MAIN HARNESS (FRONT
SENSOR BUS LH).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 20 sec-
onds or more.
2) Remove the instrument panel lower cover
and disconnect the connectors (AB7) and
(AB2).
3) Remove the instrument panel side cover on
the passenger’s side and disconnect the con-
nectors (AB9) and (AB10).
4) Disconnect the connectors (AB17, AB6,
AB18) from airbag control module.
5) Connect the connector (1AG) in the test har-
ness AG to the connectors (AB17, AB6, AB18).
6) Disconnect the front sub sensor (LH), and
then connect the connector (1H) in the test har-
ness H to connector (AB13).
7) Measure the resistance between connector
(4AG) in the test harness AG and connector
(3H) in the test harness H.
Connector & terminal
(4AG) No. 7 — (3H) No. 5:
(4AG) No. 9 — (3H) No. 6:
Is the resistance less than 10
:? Go to step 3.
Replace the airbag
main harness
along with body
harness.

CHECK AIRBAG MAIN HARNESS (FRONT
SENSOR BUS LH).
Measure the resistance between connector
(4AG) in the test harness AG and chassis
ground, and the resistance between connector
(4AG) in the test harness AG and connector
(3H) in test harness H.
Connector & terminal
(4AG) No. 7 — Chassis ground:
(4AG) No. 9 — Chassis ground:
(4AG) No. 7 — (4AG) No. 9:
Is the resistance 1 M
: or
more?
Go to step 4.
Replace the airbag
main harness
along with body
harness.

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 front
sub sensor (LH).
<Ref. to AB-21,
REMOVAL, Front
Sub Sensor.>
Replace the airbag
control module if
not operating nor-
mally even after
replacing the sen-
sor. <Ref. to AB-
20, REMOVAL, Air-
bag Control Mod-
ule.>
Go to step 5.

CHECK FOR ANY OTHER DTC ON DISPLAY. Is any other DTC displayed?
Check DTC using
“List of Diagnostic
Trouble Code”.
<Ref. to AB(diag)-
38, LIST, List of
Diagnostic Trouble
Code (DTC).>
Finish the diagno-
sis.
