SUPPLEMENTAL RESTRAINT SYSTEMS  AIRBAG SYSTEM(for Type B)  B1691  Lost Communication with No.2 Side Satellite Sensor Bus RH  B1694  No.2 Side Satellite Sensor Bus RH Initialization Incomplete  


DESCRIPTION

The side collision sensor RH circuit consists of the airbag sensor assembly, No. 1 side airbag sensor RH and No. 2 side airbag sensor RH.

The No. 1 side airbag sensor RH and No. 2 side airbag sensor RH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the SRS should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor RH circuit.
