DTC B1623/81: Side Airbag Sensor Assembly RH Initialization Incomplete: Description

The side collision sensor RH circuit (to determine deployment of the front seat airbag assembly RH, front seat outer belt assembly RH, rear window curtain shield airbag assembly and curtain shield airbag assembly RH) is composed of the airbag ECU assembly, door side airbag sensor RH and side airbag sensor assembly RH.

The door side airbag sensor RH and side airbag sensor assembly RH detect impacts to the vehicle and send signals to the airbag ECU assembly to determine if the airbag should be deployed.

This DTC is stored when a malfunction is detected for the side collision sensor RH circuit (to determine deployment of the front seat airbag assembly RH, front seat outer belt assembly RH, rear window curtain shield airbag assembly and curtain shield airbag assembly RH).
