Supplemental Restraint System (SRS) for a 2017 Toyota Corolla. The SRS, commonly known as the airbag system, is a critical component for vehicle safety. Proper maintenance and understanding of the SRS are essential for ensuring it functions correctly in the event of a collision.
Supplemental Restraint System (SRS) Overview
The SRS includes:
- Airbags: Front, side, curtain, and knee airbags.
- Sensors: Impact sensors, seat position sensors, and occupant classification sensors.
- Control Module: The airbag control module (ACM) or SRS control unit manages the deployment of airbags based on sensor input.
- Wiring and Connectors: Electrical wiring and connectors that link all components.
Components and Diagram
Below is a general overview of the SRS components and their typical locations:
- Front Airbags: Located in the steering wheel for the driver and in the dashboard for the front passenger.
- Side Airbags: Installed in the front seat side bolsters.
- Curtain Airbags: Located along the roofline on both sides of the vehicle.
- Knee Airbags: Found below the steering column and dashboard for driver and passenger, respectively.
- Impact Sensors: Located at various points around the vehicle, including the front bumper, sides, and rear.
- SRS Control Module: Typically located under the center console or the dashboard.
- Occupant Classification System (OCS): Includes sensors in the front passenger seat to detect the presence and weight of the occupant.

Steps to Access SRS Components
- Safety First: Disconnect the battery and wait for at least 90 seconds before working on the SRS to prevent accidental airbag deployment.
- Remove Trim Panels: Carefully remove interior trim panels to access airbags and sensors. Use trim removal tools to avoid damage.
- Locate the SRS Control Module: Typically found under the center console or behind the dashboard.
- Inspect Wiring and Connectors: Look for damaged wires, loose connectors, or corrosion. Repair or replace as needed.
- Check Sensors: Ensure all impact sensors are securely mounted and undamaged.
Troubleshooting SRS Issues
- Warning Light: If the SRS warning light is illuminated on the dashboard, it indicates a fault in the system. Use an OBD-II scanner with SRS capabilities to read the trouble codes.
- Common Issues: Common problems include faulty sensors, damaged wiring, or a malfunctioning control module.
