DESCRIPTION The side collision sensor RH circuit (bus 1) consists of the airbag ECU assembly, side airbag pressure sensor RH and side No. 2 airbag sensor RH. The side airbag pressure sensor RH and side No. 2 airbag sensor RH detect impacts to the vehicle and send signals to the airbag ECU assembly to determine if the airbags and pretensioners should be deployed. DTC B1630 is stored when a malfunction is detected in the side No. 2 airbag sensor RH.
