DTC B1642/81 Lost Communication with Side Satellite Sensor Bus RH

DTC B1647/82 Lost Communication with Side Satellite Sensor Bus LH


DESCRIPTION

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 B1642/81 or B1647/82 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, rear seat side airbag LH or RH and curtain shield airbag LH or RH).
