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) consists of the airbag ECU assembly, side airbag sensor assembly LH, rear airbag sensor LH and door side airbag sensor LH.

The side airbag sensor assembly LH, rear airbag sensor LH and door side airbag sensor LH detect impacts to the vehicle and send signals to the airbag ECU 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.
