3. OPERATION
According to the collision deceleration rate that each collision G sensor reads, the air bag unit
sends out about 2 to 4 or higher Amp current. This current generates some heat, which fires the
detonator in the inflator. This table shows the basic inner resistance of the air bag related
module and the basic instant current necessary for a firing.

▶
Please do not connect a tester to any air bag connector or single item to measure the
supplied power 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.
