7.2.2. SENSORS
A. FRONT IMPACT SENSOR
(FIS)
These sensors are mounted on vertical members
of front end module on the both side i.e. RH & LH,
so that, it will react almost instantly to the sudden
deceleration that results from the front impact.
They send signal to the SRS ECU and help in
firing the restraints in the minimum possible time.
These sensors along with SRS ECU are equipped
with
“Safe Mode”
function to ensure that the SRS
fires only when there is a physical crash event of
significant severity.
MAKE: BOSCH
SUPPLY VOLTAGE RANGE: 5.25 V to 16.5
! CAUTION
Do not attempt to check or replace any impact
sensor unless the vehicle battery is disconnected.
This renders the sensing system "powered OFF".
Wait for at least 10 minutes after the battery is
disconnected and then start the relevant
work/repair.
