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, and rear airbag sensor LH.

The side airbag sensor LH and rear airbag sensor LH detect impacts to the vehicle and send signals to the center airbag sensor assembly to determine

if the airbag should be deployed.

Theses 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).
