DTC    B1698/82    Passenger Side Door Side Airbag Sensor Initialization Incomplete

for Preparation Click here


DESCRIPTION

The circuit for the passenger side - side collision sensor (to determine deployment of the front seat side airbag (passenger side) and curtain shield airbag (passenger side)*1) is composed of the center airbag sensor assembly, passenger side - side airbag sensor (for front side) and passenger side - side airbag sensor (for rear side)*1.
The passenger side - side airbag sensor (for front side) and passenger side - side airbag sensor (for rear side)*1 detect impacts to the vehicle and send signals to the center airbag sensor assembly to determine if the airbag should be deployed.
DTC B1698/82 is recorded when a malfunction is detected in the circuit for the passenger side - side collision sensor (for front side) (to determine deployment of the front seat side airbag (passenger side) and curtain shield airbag (passenger side)*1).

DTC No.
