Side Air Bag: Description and Operation
Side Impact Modules
INFLATABLE RESTRAINT SIDE IMPACT MODULES
The side impact modules are located in the seat backs of driver and passenger front seat. The side impact modules contain a housing, inflatable air bag,
initiating device, and a canister of gas generating material. The initiator is part of the side impact module deployment loop. When a side impact of
sufficient force occurs, the side impact sensor (SIS) detects the impact and sends a signal to the sensing and diagnostic module (SDM). The SDM
compares the signal received from the SIS to a value stored in memory. When the generated signal exceeds the stored value, the SDM will cause current
to flow through the side impact air bags deployment loop. The SDM, side impact modules and the connecting wires makeup the side deployment loops.
The SDM continuously monitors the deployment loops for malfunctions and turns the AIR BAG indicator ON if a fault is present.
Each side impact module is equipped with a shorting bar located on the connector of the module. The shorting bar shorts the side impact modules
deployment loop circuitry to prevent unwanted deployment of the air bag when servicing the inflator module.
