SUPPLEMENTAL RESTRAINT SYSTEMS  AIRBAG SYSTEM(for Type C)  B167B  Lost Communication with Front Door Pressure Sensor LH  B167C  Front Door Pressure Sensor LH Initialization Incomplete  


DESCRIPTION

The side collision sensor LH circuit consists of the airbag sensor assembly and side airbag pressure sensor LH.

The side airbag pressure 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 side collision sensor LH circuit.
