Toyota RAV4 (XA40) 2013-2018 Service Manual: Driver side rear airbag sensor circuit malfunction
Description
The rear airbag sensor lh consists of parts including the diagnostic circuit and the lateral deceleration sensor.
When the center airbag sensor receives signals from the lateral deceleration sensor, it determines whether or not the srs should be activated.
Dtc b1630/23 is recorded when a malfunction is detected in the rear airbag sensor lh circuit.
