SUPPLEMENTAL RESTRAINT SYSTEMS AIRBAG SYSTEM(for Type A) B166C Front Door Pressure Sensor RH B166F Front Door Pressure Sensor Threshold Malfunction (RH)

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 airbag pressure sensor RH or airbag sensor assembly.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Warning Indicate	Test Mode / Check Mode
B166C	Front Door Pressure Sensor RH	Either condition is met: · A side airbag pressure sensor RH malfunction. · An airbag sensor assembly malfunction.	· Side airbag pressure sensor RH · Airbag sensor assembly	Comes on	Not applicable
B166F	Front Door Pressure Sensor Threshold Malfunction (RH)	Either condition is met: · A side airbag pressure sensor RH malfunction. · An airbag sensor assembly malfunction.	· Side airbag pressure sensor RH · Airbag sensor assembly	Comes on	Not applicable
