Step
1 CHECK POOR CONTACT OF CONNECTORS.
Check for poor contact of the connectors
between the airbag control module and the pas-
senger's airbag module.
2 CHECK PASSENGER'S AIRBAG MODULE.
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 side cover on
passenger's side.
3) Disconnect the connector (AB27) from
(AB4).
4) Connect the connector (1P) in the test har-
ness P to connector (AB4).
5) Connect the airbag resistor to the connec-
tors (2P) and (3P) of test harness P.
6) Connect the battery ground terminal and
turn the ignition switch to ON.
3 CHECK AIRBAG MAIN HARNESS (PASSEN-
GER'S AIRBAG HARNESS).
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 the con-
nectors (2P) and (3P) of test harness P.
3) Remove the instrument panel lower cover
and disconnect the connector (AB26) from
(AB2).
4) Disconnect the connector (AB3) from airbag
control module, and connect the connector (1R)
in the test harness R.
5) Measure the resistance between connector
(2R) in the test harness R and connectors (2P)
and (3P) in the test harness P.
Connector & terminal
(2R) No. 3 — (2P) No. 1:
(2R) No. 5 — (2P) No. 2:
(2R) No. 9 — (3P) No. 3:
(2R) No. 13 — (3P) No. 4:
4 CHECK AIRBAG MAIN HARNESS (PASSEN-
GER'S AIRBAG HARNESS).
Measure the resistance between connector
(2R) terminals in the test harness R, and
between connector (2R) and chassis ground.
Connector & terminal
(2R) No. 3 — (2R) No. 5:
(2R) No. 3 — Chassis ground:
(2R) No. 5 — Chassis ground:
(2R) No. 9 — (2R) No. 13:
(2R) No. 9 — Chassis ground:
(2R) No. 13 — Chassis ground:
5 CHECK AIRBAG CONTROL MODULE.
1) Connect all connectors.
2) Erase the memory.
3) Perform the Inspection Mode.
4) Read the DTC.
Diagnostic Chart with Trouble Code
Is there poor contact?
Does the airbag warning light
illuminate for 6 seconds and go
off?
Is the resistance less than 10
Ω?
Is the resistance 1 MΩ or
more?
Is the same DTC displayed?
