DTC B1693/81 Door Side Airbag Sensor RH Initialization Incomplete


DESCRIPTION

HINT:
"Door side airbag sensor RH" refer to the side airbag sensor RH.
  1. The circuit for the side collision sensor LH or RH (to determine deployment of the front seat airbag LH or RH, rear seat side airbag LH or RH and curtain shield airbag LH or RH) is composed of the center airbag sensor, side airbag sensor LH or RH, and rear airbag sensor LH or RH.
    The side airbag sensor LH or RH and rear airbag sensor LH or RH detect impacts to the vehicle and send signals to the center airbag sensor to determine if the airbag should be deployed.
    DTC B1693/81 is stored when a malfunction is detected in the circuit for the side collision sensor LH or RH (to determine deployment of the front seat airbag LH or RH and curtain shield airbag LH or RH).
    DTC B1638/82 is stored when a malfunction is detected in the circuit for the rear collision sensor LH or RH (to determine deployment of the rear seat side airbag LH or RH and curtain shield airbag LH or RH).
