DESCRIPTION

The side collision sensor LH circuit (to determine deployment of the front seat airbag assembly LH, curtain shield airbag assembly LH and front seat outer belt assembly LH) is composed of the airbag ECU assembly, side airbag sensor assembly LH and side No. 2 airbag sensor assembly LH.

The side airbag sensor assembly LH and side No. 2 airbag sensor assembly LH detect impacts to the vehicle and send signals to the airbag ECU assembly to determine if the airbag and pretensioner should be deployed.

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