DTC B162B: Side Airbag Sensor Assembly No. 2 Lost Communication (RH); DTC B162C: Side Airbag Sensor Assembly No. 2 Initialization Error (RH); DTC B1694: No. 2 Side Satellite Sensor Bus RH Initialization Incomplete [12/2019 - 11/2023]: Description

The side collision sensor RH circuit (bus 2) consists of the airbag sensor assembly and side No. 2 airbag sensor RH.

The side No. 2 airbag sensor RH detects impacts to the vehicle and sends signals to the airbag sensor assembly to determine if the airbags, pretensioners and selectable force limiter should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor RH circuit (bus 2).
