Deployment; Air Bag System Deployment (Firing Loop); Resistance Of Air Bag Wiring - SSANGYONG Korando 2012 Manual

3. DEPLOYMENT

1) Air Bag System Deployment (Firing Loop)

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.
Air bag module
Resistance at -30 to
+85°C
Non-ignition current
at +85°C
All-ignition current at -
35°C
Periodic
test current
Insulating resistance
- 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.
