DTC B1623/81 Side Airbag Sensor Assembly RH Initialization Incomplete; DTC B1628/82 Side Airbag Sensor Assembly LH Initialization Incomplete; DTC B1633/81 Rear Airbag Sensor Assembly RH Initialization Incomplete; DTC B1638/82 Rear Airbag Sensor Assembly LH Initialization Incomplete: Description
The circuit for the side collision sensor LH or RH (to determine deployment of the front seat side airbag LH or RH and curtain shield airbag LH or RH) is composed of the center airbag sensor, side airbag sensor LH or RH, and rear airbag sensor LH or RH.
The side airbag sensor LH or RH and rear airbag sensor LH or RH detect impacts to the vehicle and send signals to the center airbag sensor to determine if the airbag should be deployed.
DTC B1623/81 or B1628/82 is recorded when a malfunction is detected in the circuit for the side collision sensor LH or RH (to determine deployment of the front seat side airbag LH or RH and curtain shield airbag LH or RH).
DTC B1633/81 or B1638/82 is recorded when a malfunction is detected in the circuit for the rear collision sensor LH or RH (to determine deployment of the rear seat side airbag LH or RH and curtain shield airbag LH or RH).
