The airbag control unit monitors all of the crash sensors and fires the airbag once certain conditions are met. The airbag control unit also checks the sensors on ignition to ensure they are all in working order.
If a crash occurs where the airbag should have been deployed, a defective airbag control unit can fail to send the signal to fire. The sensors sent the signal to fire the airbag, but the defective control unit did not process the information correctly.
Not all collisions trigger the airbag. See collision requirements not met.
The airbag dashboard light illuminates when the airbag control unit detects a problem with the airbag system. If the control unit is defective, it may be misreading some of the sensors and activating the light.
