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.
DTC B1625/22 is stored when a malfunction is detected in the No. 1 side airbag sensor LH.
