DESCRIPTION
The side collision sensor LH circuit (bus 1) consists of the airbag sensor assembly, door side airbag sensor LH, No. 1 side airbag sensor LH and No. 2 side airbag sensor LH.
The door side airbag sensor LH, No. 1 side airbag sensor LH and No. 2 side airbag sensor LH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags and pretensioners should be deployed.
These DTCs are stored when a malfunction is detected in the door side airbag sensor LH.
