B1698/82 - Door Side Airbag Sensor LH Initialization Incomplete

DESCRIPTION

The side collision sensor LH circuit (to determine deployment of the front seat side airbag assembly LH, rear seat side airbag assembly LH and

curtain shield airbag assembly LH) is composed of the center airbag sensor assembly, side airbag sensor LH (for rear side), rear airbag sensor LH

and side airbag sensor LH (for front side).

The side airbag sensor LH (for rear side), rear airbag sensor LH and side airbag sensor LH (for front side) detect impacts to the vehicle and send

signals to the center airbag sensor assembly to determine if the airbag should be deployed.

These DTCs are recorded when a malfunction is detected for the side collision sensor LH circuit (to determine deployment of the front seat side

airbag assembly LH, rear seat side airbag assembly LH and curtain shield airbag assembly LH).
