INSTALLATION
NOTICE:
Never use SRS parts from another vehicle. When re-
placing parts, replace them with new parts.
Never reuse the airbag sensor assembly involved in
a collision when the airbag has deployed.
Never repair a sensor in order to reuse it.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Using a torx wrench, install the airbag sensor assembly
with 3 screws.
Torx wrench: T40 (Part No.09042±00020 or locally
manufactured tool)
Torque: 20 N´m (200 kgf´cm, 14 ft´lbf)
(b) Connect the airbag sensor connectors.
NOTICE:
Installation of the connector is done with the sensor
assembly installed. Make sure the sensor assembly
is installed to the specified torque.
If the sensor assembly has been dropped, or there are
cracks, dents or other defects in the case, bracket or
connector, replace the sensor assembly with a new
one.
When installing the senor assembly, take care that
the SRS wiring does not interfere with other parts and
is not pinched between other parts.
After installing , shake the sensor assembly to check
that there is no looseness.

INSTALLATION
1. INSTALL FRONT AIRBAG SENSOR
Install the sensor with bolt and nut, then connect the connector.
Torque: 7.8 N´m (80 kgf´cm, 69 in.´lbf)
NOTICE:
Make sure the sensor is installed to the specified
torque.
If the sensor has been dropped, or there are cracks,
dents or other defects in the case, brackets or con-
nector, replace the removed sensor. Always replace
the set bolt and nut with new ones.
The sensor set bolt and nut have been anti±rust
treated. When the sensor is removed, always replace
the set bolt and nut with new ones.
After installation, shake the sensor to check that
there is no looseness.
The front sensor is equipped with an electrical con-
nection check mechanism. Be sure to lock this mech-
anism securely when connecting the connector. If the
connector is not securely locked, a malfunction code
will be detected by the diagnostic system.
