B1690

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: B1690, B16F9; Side Airbag Sensor RH; 2013 MY FR-S [03/2012 -]
B1690 - Side Airbag Sensor RH
B16F9 - Door Side Airbag Sensor RH Mismatch

DESCRIPTION

The side collision sensor RH circuit (to determine deployment of the front seat airbag assembly RH, curtain shield airbag assembly RH and front seat outer belt assembly RH) is composed of the airbag ECU assembly, side airbag sensor assembly RH, side No. 2 airbag sensor assembly RH and rear airbag sensor RH and No. 2 airbag sensor assembly.

The side airbag sensor assembly RH detects impacts to the vehicle and sends signals to the airbag ECU assembly to determine if the airbag should be deployed.

These DTCs are stored when a malfunction is detected in the side airbag sensor assembly RH.





WIRING DIAGRAM

Refer to DTCs B1622, B1623, B1632, B1633, B1642, B1692 and B1693 B1622.
