DTC Code DTC Name
B1627/82 Lost communication with Side Airbag Sensor LH
B1628/82 Side Airbag Sensor Assembly LH Initialization Incomplete
B1637/82 Lost Communication with Rear Airbag Sensor LH
B1638/82 Rear Airbag Sensor Assembly LH Initialization Incomplete

DESCRIPTION

The side collision sensor LH circuit (to determine deployment of the front seat airbag assembly LH, rear seat airbag assembly LH and curtain shield airbag assembly LH) is composed of the airbag sensor assembly, side airbag sensor assembly LH and rear airbag sensor LH.

The side airbag sensor assembly LH and rear airbag sensor LH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor LH circuit.
