Circuit/System Description
WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
For an overview of the component/system, refer to:Supplemental Inflatable Restraint System Description and Operation
| Circuit | Description |
|---|---|
| Control - Terminal 1 | The output circuit is switched to 12 V to activate the component. |
| Control - Terminal 2 | The output circuit is switched to ground to activate the component. |
| Component | Description |
|---|---|
| F101 Passenger Instrument Panel Air Bag | The pyrotechnic unit contains an ignitor, which, when supplied with voltage, ignites the propellant in the gas generator. |
| K36 Inflatable Restraint Sensing and Diagnostic Module | The control module monitors several sensors that can detect a collision. When a collision is detected, the control module will trigger certain air bags and seat belt pretensioners, depending on the angle and severity of the impact. |
During a side or frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy an air bag or pretensioner. There are 2 shorting bars which will short the control circuits together when the connector is disconnected. This will help to prevent unwanted deployment of the air bag or pretensioner during servicing.
