4. Construction and Operation
Side Airbag Sensor Assembly
1) Description
The side airbag sensor assembly is mounted on the right and left center pillars. It receives signals from
the side airbag sensor enclosed in the side airbag sensor assembly and judges whether the side airbag must
be activated or not.
2) Construction and Operation
The side airbag sensor assembly consists of side airbag sensor, safing sensor, etc.
a. Side Airbag Sensor
The side airbag sensor is enclosed in the side airbag sensor assembly based on the acceleration of the
vehicle that occurs during a side collision. The distortion created in the sensor is converted into an elec-
tric signal. This signal is a linear representation of the acceleration rate.
b. Safing Sensor
The safing sensor is enclosed in the side airbag sensor assembly. The sensor turns ON if an acceleration
force that is higher than a predetermined value is applied to the safing sensor as a result of a side colli-
sion.
Airbag Sensor Assembly
1) Description
The airbag sensor assembly is mounted on the center floor under the instrument panel.
When the airbag sensor assembly receives the airbag activation signal from the side airbag sensor assem-
bly, it applies current to the inflator.
Furthermore, the airbag sensor assembly diagnoses a system malfunction of the side airbag system.
This is the same airbag sensor assembly that is used for the
SRS airbag for the driver and front passenger.
2) Construction and Operation
The airbag sensor assembly consists of ignition control circuit, back up power source, diagnosis circuit,
memory circuit, etc.
a. Ignition Control Circuit
The ignition control circuit performs a prescribed calculation based on the signal output by the airbag
sensor and the front airbag sensor. If these calculated values are larger than a predetermined value, it
activates the ignition operation.
b. Back-Up Power Source
The back-up power source consists of a back-up capacitor and a DC-DC converter. In case of a power
system failure during a collision, the back-up capacitor discharges and supplies electric power to the
system. The DC-DC converter is a boosting transformer when the battery voltage drops below a certain
level.
c. Diagnosis Circuit
This circuit constantly diagnoses the system for any malfunction. When a malfunction is detected, it
lights up the
SRS warning light on the combination meter to alert the driver.
d. Memory Circuit
When a malfunction is detected by the diagnosis circuit, it is coded and stored in this memory circuit.
