DTC Code	DTC Name
B1625/22	Front Passenger Side - Side Airbag Sensor Malfunction

DESCRIPTION

for LHD:

The front passenger side - side collision sensor circuit (to determine deployment of the front seat side airbag assembly RH and curtain shield airbag assembly RH) is composed of the center airbag sensor assembly, side airbag sensor RH (for front side), rear airbag sensor RH, side airbag sensor RH (for rear side) and front floor airbag sensor.

The side airbag sensor RH (for front side) detects impacts to the vehicle and sends signals to the center airbag sensor assembly to determine if the airbag should be deployed.

DTC B1625/22 is recorded when a malfunction is detected in the side airbag sensor RH (for front side).
