Symptoms & Diagnosis
Warning Signs of a Failing Airbag Control Module
Airbag warning light stays on, even after starting the car
Airbags fail to deploy in an accident
Airbags deploy for no reason
Diagnostic trouble codes (DTCs) related to the airbag system
Issues with other safety systems linked to the airbag module
Testing the Airbag Control Module
It can be tricky to know if the airbag control module is the problem. Here's how to check:
Scan for Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to retrieve any codes related to the airbag system. Specific codes pointing to the module itself are a strong indicator.
Check Wiring and Connections: Inspect all wiring and connectors leading to the airbag control module for damage, corrosion, or loose connections.
Consult a Professional: Airbag systems are complex. A qualified mechanic can use specialized tools to test the module and other components, like sensors and airbags, to pinpoint the issue.
Common Failure Causes
Corrosion: Moisture and humidity can corrode the module's internal components.
Electrical Surges: Power surges in the vehicle's electrical system can damage the module.
Accident Damage: Even minor accidents can damage the module, even if the airbags don't deploy.
Age: Over time, the module's components can simply wear out.

What to Look For
Proper Fit: Make sure the part is designed for your vehicle's year and model.
