SUPPLEMENTARY RESTRAINT SYSTEM (SRS)

11.1.6.2.2. 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 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.
