DTC B167B: Lost Communication with Front Door Pressure Sensor LH; DTC B167C: Front Door Pressure Sensor LH Initialization Incomplete [11/2018 - 02/2019]: Description

WARNING: This page is about a different car, the 2020 Toyota RAV4 and 2019 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

The side collision sensor LH circuit consists of the airbag ECU assembly, side airbag pressure sensor LH and No. 2 side airbag sensor assembly LH.

The side airbag pressure sensor LH detects impacts to the vehicle and send signals to the airbag ECU assembly to determine if the SRS should be deployed.

These DTCs are stored when a malfunction is detected in the circuit for the side collision sensor LH circuit.
