REMOVAL SERVICE POINT
NEGATIVE BATTERY CABLE
DISCONNECTION
Turn the ignition key to the “LOCK” position, disconnect the
negative battery cable from the battery and tape the terminal.
Caution
Wait at least 60 seconds after disconnecting the battery
cable before doing any further work. The SRS system
is designed to retain enough voltage to deploy the air
bag even after the battery has been disconnected. Serious
injury may result from unintended air bag deployment
if work is done on the SRS system immediately after
the battery cable is disconnected.

INSTALLATION SERVICE POINTS
PRE-INSTALLATION INSPECTION
(1) Before any front impact sensor is installed in the vehicle,
it must be visually inspected. If a dent, crack or other
deformation, or rust, is detected, discard the sensor and
replace it with a new one that passes the visual inspection.
(2) Before any front impact sensor is installed in the vehicle,
the resistance between its terminals must be confirmed
to be within the standard value.
Standard value: 2,000 40
Use the digital multi meter. If the resistance is not within
that standard value range, discard it and replace it with
a new one that has the standard value.
FRONT IMPACT SENSOR INSTALLATION
(1) Bend the wiring harness slightly (to the extent that there
is no slack), and clip securely by using the clip of the
front impact sensor.
(2) Install the front impact sensor so that there is close
adherence of the upper surface of the front impact sensor
and the installation surface of the upper frame (lower).
Caution
The SRS may not activate properly if a front impact
sensor is not installed properly, which could result
in the SRS system not operating properly during a
collision.
