SUPPLEMENTAL RESTRAINT SYSTEMS AIRBAG SYSTEM(for Type B) B1615 Front Airbag Sensor (LH)

DESCRIPTION

The front airbag sensor LH circuit consists of the airbag sensor assembly and front airbag sensor LH.

The front airbag sensor LH detects impacts to the vehicle and sends signals to the airbag sensor assembly to determine if the SRS should be deployed.

DTC B1615 is stored when a malfunction is detected in the front airbag sensor LH or airbag sensor assembly.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Warning Indicate	Test Mode / Check Mode
B1615	Front Airbag Sensor (LH)	Either condition is met: · A front airbag sensor LH malfunction. · An airbag sensor assembly malfunction.	· Front airbag sensor LH · Airbag sensor assembly	Comes on	Not applicable
