SUPPLEMENTAL RESTRAINT SYSTEMS AIRBAG SYSTEM(for Type B) B1632 Curtain Shield Airbag Sensor Lost Communication (RH) B1633 Curtain Shield Airbag Sensor Initialization Error (RH)

DESCRIPTION

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

The No. 2 side airbag sensor RH detects impacts to the vehicle and sends 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 circuit for the side collision sensor RH circuit.
