⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on airbag systems to prevent accidental deployment.
•Allow the vehicle to sit for at least 10 minutes after disconnecting the battery to ensure all capacitors in the airbag system discharge.

Symptoms

•Airbag warning light illuminated on the dashboard
•Possible error codes related to airbag system (e.g., SRS codes)
•Seatbelt pretensioners may not deploy during an accident
•Warning message displayed on the driver information system
•Unresponsive airbag deployment during a simulated test (if applicable)

Diagnostic Steps

1
Scan the vehicle's OBD-II system using a compatible scanner to retrieve SRS error codes.
2
Inspect the airbag system wiring and connectors under the driver's and passenger's seats for damage or loose connections.
3
Check the status of the seatbelt sensors to ensure they are functioning properly.
4
Look for any issues with the airbag control module (ACM) including corrosion or water damage.
5
Verify the condition of the battery and electrical connections, as low voltage can impact the airbag system.
