The front airbag sensor LH circuit consists of the airbag sensor with ECU assembly and front airbag sensor LH.
The front airbag sensor LH detects impacts to the vehicle and sends signals to the airbag sensor with ECU assembly to determine if the airbags and pretensioners should be deployed.
DTC B1615 is stored when a malfunction is detected in the front airbag sensor LH.
