DTC B1642: Side Satellite Sensor Bus Lost Communication (RH); DTC B1643: Side Satellite Sensor Bus Initialization Error (RH) [09/2019 - 12/2021]: Description
The side collision sensor RH circuit (bus 1) consists of the airbag sensor assembly, door side airbag sensor RH and No. 2 side airbag sensor RH.
The door side airbag sensor RH and No. 2 side airbag sensor RH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags and pretensioners should be deployed.
These DTCs are stored when a malfunction is detected in the side collision sensor RH circuit (bus 1).
