DTC DTTECTING CONDITION:
• |
Side airbag
harness (RH) is faulty.
|
• |
Side airbag module (RH) is faulty.
|
• |
Airbag control module is faulty.
|
Important | ||
• |
Before diagnosing the airbag
system, be sure to turn the ignition switch to OFF, disconnect the ground
cable from battery, and wait more than 20 seconds before starting
to work.
|
|
• |
Before replacing the airbag module, seat belt pretensioner
roll connector, control module, and sensor, reconnect each part
and confirm that the warning light operates properly.
|
|
• |
When inspecting the airbag main harness, disconnect
the driver’s airbag module and passenger’s airbag
module connectors for safety reasons.

WIRING DIAGRAM:
CHECK SIDE AIRBAG MODULE.
Turn the ignition switch to OFF, disconnect the battery ground cable, and wait more than 20 seconds.Disconnect the connector (AB20) from the seat belt pretensioner (RH).
Disconnect the connector (AB28) from (AB11), and connect the connector (1F) in test harness F to (AB11).
Connect the airbag resistor to connector (3F) in test harness F.
Connect the battery ground cable, and turn the ignition switch to ON.
Does the airbag warning light operate properly?
Yes |
Replace the front seat with side airbag module (RH).
No |
CHECK SIDE AIRBAG HARNESS (RH).
Turn the ignition switch to OFF, disconnect the battery ground cable, and wait more than 20 seconds.Disconnect the airbag resistor from test harness F.
Disconnect the connector (AB8) from air bag control module.
Connect the connector (1R) in test harness R to connector (AB8).
Measure the resistance between connector (3R) in test harness R and connector (3F) in test harness F.
