SUPPLEMENTAL RESTRAINT SYSTEMS AIRBAG SYSTEM(for Type B) B163A Side Airbag Sensor Assembly No.2 (LH) B163B Side Airbag Sensor Assembly No.2 Lost Communication (LH)

DESCRIPTION

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

The No. 1 side airbag sensor LH 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 No. 1 side airbag sensor LH or airbag sensor assembly.
