An airbag is worthless if the airbag sensor isn't working properly. Many car models include sensors that automatically reset after an impact. However, not all vehicles are designed this way, and the sensor may have to be replaced or reset manually after an impact. If your airbags have deployed, it's a good idea to test the sensor. Testing the sensor is an easy task.

Testing the airbag sensor is an easy task that is very necessary.
Materials Needed:
Owner’s Manual
Pencil
Paper

Step 1 – Determine Problem
Whenever the engine is started, the control modules for the airbag will automatically self check the crash sensors. What this means is that you will only need to test the airbag sensor if the airbag warning light is lit up.
Step 2 – Scan Tool
You will need to get out a scan tool and use it on your airbag system. Make sure that you have your owner’s manual out so that you can understand what the trouble code means. It is a good idea to write down this trouble code for future reference.
Step 3 – Troubleshoot
Once you have the trouble code down, you will need to go ahead and read up on your owner’s manual so that you will be able to understand the all of the scenarios for the possible problem.
