AIRBAG SYSTEM, Diagnostic DTC:B1630/23

DESCRIPTION

• for LHD:

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

  The rear airbag sensor LH detects impacts to the vehicle and sends signals to the center airbag sensor assembly to determine if the airbag should be deployed.

  DTC B1630/23 is recorded when a malfunction is detected in the rear airbag sensor LH.
