Circuit/System Description
WARNING: This page is about a different car, the 2022 Cadillac CT5. However, it is still accessible from the selected car via links, so may be relevant.
During a side or frontal crash of sufficient force the Restraints Control Module (SDM) will allow current to flow through the deployment loop in order to deploy an air bag or pretensioner.

| 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 |
|---|---|
| F112 Seat Belt Retractor Pretensioner | The pyrotechnic unit contains an ignitor, which, when supplied with voltage, ignites the propellant in the gas generator. |
| K36 Restraints Control 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. |
