Center airbag sensor assembly malfunction

The center airbag sensor consists of the airbag sensor, the safing sensor, the drive circuit, the diagnosis circuit and the ignition control.

If the center airbag sensor receives signals from the airbag sensor, it determines whether or not the srs should be activated.

Dtc b1000/31 is recorded when a malfunction is detected in the center airbag sensor.

When a malfunction code is displayed simultaneously with dtc b1000/31, repair the malfunction indicated by this code (except dtc b1000/31) first.
