DESCRIPTION
The side airbag sensor assembly LH consists of parts such as the safing sensor, the diagnostic circuit and the lateral deceleration sensor.
When the airbag sensor assembly receives signals from the lateral deceleration sensor, it determines whether or not the SRS should be activated.
DTC B1625/22 is set when a malfunction is detected in the side airbag sensor assembly LH and rear airbag sensor LH circuit.
