1. CAUTIONS FOR AIR BAG OPERATION
When there is any deployed air bag (including seat belt pretensioner), the air bag unit should be
replaced. Any DTC (Diagnostic Trouble Code) in the air bag unit should not be cleared since the
unit has data for status when the air bag was deployed as well as information related to the air bag
deployment.
Note that the used components related to the air bag, especially the air bag unit, should be
packaged in an air tight container to prevent any damage.
Do not connect a tester to any connector or component to check supply voltage or resistance of ai
r
bag related components. The detonator may explode due to a sudden extra power supplied by the
tester.
Before removing or installing any air bag related components, disconnect the negative battery
cable. 1.

Collision sensors, a kind of impact G (acceleration) sensor, detect the lateral and longitudinal collisions
and determine whether or not to deploy air bags. The roles of each collision sensor are as follows:
Front G sensors (inside the air bag unit)
Send signals to the front air bags (driver and passenger air bags) and the driver's and front
passenger's seat belt pretensioners. When the front collision G sensor sends out only the air bag
deployment signal, the signal deploys the two front air bags and activates their seat belt
pretensioners.
Once an air bag deploys, its repair parts vary according to the deployment situation and damage to the
vehicle from collision. Needed repairs also slightly vary between the front air bags and the curtain air
bags. The following are the differences:
Replacement parts when the front air bags deploy:
Air bag unit and its wiring (including connector), seat belt pretensioner and its wiring (including
connector), whole front air bags, instrument panel (IP)

driver/passenter air bags are deplyed when the front air bag is deployed like as they did.

5. AIR BAG WARNING LAMP OPERATIONAL CONDITIONS
The air bag warning lamp on the instrument panel has a few operational conditions. The following are
the conditions:
When Turning the Ignition Switch to ON Position Initially ▶
The air bag unit performs a turn-on test when the ignition is turned on initially. The air bag unit flashes the
air bag warning lamp 6 times at 1 Hz interval. After that, the air bag warning lamp will go off if no
malfunction have been detected.
When the Air Bag Unit Detects Any Malfunctions in Unit ▶
When the Air Bag Unit Detects Any Intermittent Failure ▶ When it is recorded as a system failure in the air bag unit, the air bag warning lamp on the instrument
panel comes on for about 6 seconds and goes off for 1 second. Then the waning lamp stays on.
When, due to an error from outside the system, the intermittent failure signal is received 5 times or less,
the air bag warning lamp comes on for about 6 seconds and then, goes off.
