Airbag System (for Hatchback without VSC) (from 07/2011)

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM (for Hatchback without VSC): B161A/8A: Lost Communication with Front Satellite Sensor Bus
B161A/8A - Lost Communication with Front Satellite Sensor Bus

DESCRIPTION

The front collision sensor circuit (front airbag sensor RH circuit and front airbag sensor LH circuit) is composed of the airbag sensor assembly, front airbag sensor RH and front airbag sensor LH.

The front airbag sensor RH or front airbag sensor LH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbag should be deployed.

DTC B161A/8A is stored when a malfunction is detected in the front collision sensor circuit (front airbag sensor RH circuit and front airbag sensor LH circuit).
