DTC B163B/86: Side Airbag Sensor Assembly No. 2 Lost Communication (LH); DTC B163C/86: Side Airbag Sensor Assembly No. 2 Initialization Error (LH) [02/2017 - 10/2017]: Description
The side collision sensor LH circuit (bus 2) consists of the airbag sensor assembly and floor side airbag sensor LH.
The floor side airbag sensor LH detects impacts to the vehicle and sends 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 LH circuit (bus 2).
