SUPPLEMENTAL RESTRAINT SYSTEMS  AIRBAG SYSTEM(for NR Series Engine)  B1630  Curtain Shield Airbag Sensor (RH)  B1632  Curtain Shield Airbag Sensor Lost Communication (RH)  


DESCRIPTION

The side collision sensor RH circuit (bus 1) consists of the airbag sensor with 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 sensor with ECU assembly to determine if the airbags and pretensioners should be deployed.

These DTCs are stored when a malfunction is detected in the side No. 2 airbag sensor RH.
