CHECK AIRBAG REAR HARNESS (PRE-
TENSIONER HARNESS LH).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 20 sec-
onds or more.
2) Disconnect the airbag resistor from test har-
ness.
3) Disconnect connector (AB19) from side air-
bag module (LH).
4) Disconnect the connector (AB31) from cur-
tain airbag module (LH).
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
(3AG) in the test harness AG and connector
(2N) in the test harness N.
Connector & terminal
(3AG) No. 12 — (2N) No. 1:
(3AG) No. 10 — (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 (PRE-
TENSIONER HARNESS LH).
Measure the resistance between connector
(3AG) terminals in the test harness AG.
Connector & terminal
(3AG) No. 10 — (3AG) No. 12:
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 (PRE-
TENSIONER HARNESS LH).
Measure the resistance between connector
(3AG) in the test harness AG and chassis
ground.
Connector & terminal
(3AG) No. 10 — Chassis ground:
(3AG) No. 12 — Chassis ground:
Is the resistance 1 M
: or
more?
Go to step 6.
Replace the airbag
rear 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 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.
