3. DEPLOYMENT
According to the collision deceleration rate that each collision G sensor reads, the air bag unit sends out
about 2~4 or higher Amp current. This current generates some heat, which fires the detonator in the
inflator.
The table shows the basic inner resistance of the air bag related module and the basic instant current
necessary for firing.
1) Air Bag System Deployment (Firing Loop)
Do not connect a tester probe to the air bag connector or air bag body to measure the supply
voltage or resistance. The detonator may explode due to a sudden extra power supplied by the
tester.
Before removing or installing any air bag related components, disconnect the negative battery
cable. -

3) CAN Communication Interface (FIS and SIS)
The CAN communication interface uses the PWM for the supply current and the current loop and
communicates with the SDM to transmit the information. The serial communication and power for the
satellite are supplied through the communication line.
Stage FIS SIS
Initial stage Tracking/Check (Self test) Same as FIS
Normal operation Checks the FIS condition and sends the result as
"OK" or "NOK", and also sends the "severity" of the
crash. Same as FIS
Voltage The FIS hardware reset was performed under 5 V,
communication voltage low Same as FIS
Fault The fault is found in the current ignition cycle but the
fault is deactivated in the next ignition cycle. Multiple faults can be found
and deactivated in the same
ignition cycle.
The FIS moves to the initial stage if 'leakage to GND' is occurred in normal operating stage to shut down
the power and prevent abnormal operation.

SIS: Side Air bag Sensor
