DESCRIPTION

The airbag sensor assembly consists of the acceleration sensor, safing sensor, drive circuit, diagnosis circuit, ignition control, etc.

If the airbag sensor assembly receives signals from the acceleration sensor and pressure sensor, it determines whether the airbags and pretensioners should be deployed.

These DTCs are stored when a malfunction is detected in the airbag sensor assembly.
