SUPPLEMENTAL RESTRAINT SYSTEMS  AIRBAG SYSTEM(for Type A)  B166D  Lost Communication with Front Door Pressure Sensor RH  B166E  Front Door Pressure Sensor RH Initialization Incomplete  


DESCRIPTION

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

The side airbag pressure 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 side collision sensor RH circuit.
