DESCRIPTION

The circuit for the driver side - side collision sensor (to determine deployment of the front seat side airbag assembly (driver side) and curtain shield airbag assembly (driver side)) is composed of the center airbag sensor assembly, side airbag sensor (driver side), and rear airbag sensor (driver side).
The side airbag sensor (driver side) and rear airbag sensor (driver side) detect impacts to the vehicle and send signals to the center airbag sensor assembly to determine if the airbag should be deployed.
DTC B1622/81, B1623/81, B1632/81, B1633/81, B1642/81, or B1643/81 is recorded when a malfunction is detected in the circuit for the driver side - side collision sensor (to determine deployment of the front seat side airbag assembly (driver side) and curtain shield airbag assembly (driver side)).
