PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) As shown in the following illustration, each ECU of this ve-
hicle is connected by communication bus and it transmits
each signal by communication. This communication bus
is self±diagnosed by Body ECU and it memorizes DTC
when it detects communication stop to ECU or commu-
nication bus +B short or GND short. There is a possibility
that Body ECU cannot self±diagnose accurately unless
it doesn't work normal. So, please note that the trouble-
shooting of Body Electrical System should be done after
confirming if Body ECU and Open door indicator works
normal by 2. ºBASIC INSPECTIONº described later.

(4) Move the SST at least 10 m (33 ft) away from the
front of the vehicle.
(5) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(6) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the negative (±) termi-
nal.
(c) Deploy the airbag.
(1) Check that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
CAUTION:
The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.
Use gloves and safety glasses when handling a steer-
ing wheel pad with the deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
the deployed airbag.
When scrapping a vehicle, deploy the airbag and
scrap the vehicle with the steering wheel pad still
installed.
When moving a vehicle for scrapping which has a
steering wheel pad with deployed airbag, use gloves
and safety glasses.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
2. DEPLOYMENT WHEN DISPOSING OF STEERING
WHEEL PAD ONLY
NOTICE:
When disposing of the steering wheel pad (with air-
bag) only, never use the customers vehicle to deploy
the airbag.
Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
