DESCRIPTION

The side airbag sensor assembly LH or RH consists of a lateral deceleration sensor, etc.

If the airbag sensor assembly receives signals from the lateral deceleration sensor, it determines whether the SRS should be activated.

DTC B1630/23, B1632/81, B1635/24 or B1637/82 is stored when a malfunction is detected in the side airbag sensor assembly LH or RH circuit.
