DESCRIPTION

The side collision sensor LH circuit (to determine deployment of the front seat airbag assembly LH, rear seat airbag assembly LH*, curtain shield airbag assembly LH and front seat outer belt assembly LH) is composed of the airbag sensor assembly, side airbag sensor assembly LH and rear airbag sensor LH.

The side airbag sensor assembly LH and rear airbag sensor LH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags and pretensioner should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor LH circuit.
