In this article, we take a look at common problems that trigger Acura and Honda check engine light.
If your Honda airbag light remains on, it most likely means that the Supplemental Restraint System (SRS) has detected a problem with the airbag system.
When your Honda airbag system is functioning properly the airbag light comes on when you turn on the ignition but should turn off once you start the engine.
If a problem is detected by the airbag system you will see the airbag light stay on. In newer models, a warning message will display on the dashboard stating the "check airbag system".
Driving a Honda with the airbag light on increases the chances of serious injury if you get into an accident.
