SEAT TRACK POSITION SENSOR CONSTRUCTION/OPERATION
CHU081057030S04
• The seat track position sensor consists of a Hall element (semi-conductor) and a magnet. The sensor converts
the effect of the magnetic flux (produced by the magnet) on the Hall element, into an electrical signal.
• When the driver’s seat is moved to a forward position, the metal plate installed near the front of the seat track
passes through the groove in the seat track position sensor. When this occurs the magnetic flux of the sensor
changes and that change is sent as an electrical signal to the SAS control module. The SAS control module
receives this signal and determines that the driver’s seat has been moved to a forward position.

Inflator Operation
1. The igniter built into the inflator begins to build up heat when the operation (deployment) signal is sent from the
SAS control module. The inflation agent is ignited by the build up of heat in the igniter.
2. The ignition of the inflation agent causes the combustion of an agent which releases nitrogen gas.
3. The nitrogen gas is cooled at the filter, and the filtrate is injected into the air bag.
Note
• The gas injection outlets for the inflators are divided into two tiers. Gas from inflator No.1 is injected from
the No.1 tier, and from the No.2 tier for inflator No.2.
