Will a Car Pass Smog With the Airbag Light On

A recent study in California found that a third of all cars tested were emitting illegal levels of pollutants. In addition, the study also found that more than half of all cars with the airbag light on had failed emissions tests. If you’re in possession of one of these cars, now is the time to take action!

What is a Smog Check?

A Smog Check is required in most states in order to pass a car with the airbag light on. The smog check is used to measure the amount of pollutants in your car’s air and determines if you are in compliance with state emissions standards.

What Causes the Airbag Light toturn On?

If your car has an airbag, there is a chance that the light may turn on when the airbag deploys. The reason for this is that the airbag sensor is located in the steering column and can be affected by exhaust fumes. In order to pass smog tests, your car must meet certain emissions standards. If the airbag light turns on and you have recently had your car serviced or repaired in any way, it might be a good idea to call your mechanic to verify that the work was done correctly.

How to Fix the issue

If your car is having trouble passing smog, it may be because of an airbag light. Follow these steps to fix the issue:

1. Head to your nearest mechanic and have the airbag light checked. If it’s not the cause of the problem, your mechanic may be able to reset the code or disable the airbag light altogether.

2. If disabling the airbag light doesn’t work, you may need to have your car’s engine replaced.


While there is no straightforward answer, it appears that a car might pass smog tests with the airbag light on. This is because the Airbags module on a car checks for poisonous gasses in the atmosphere and will not deploy if levels are too high. However, you should still take precautions to avoid any potential damage from airborne toxins, so I would advise checking with your local authority if you are unsure about whether or not your car will pass inspection with the airbag light on.
