B1630/23 | Rear Airbag Sensor RH Circuit Malfunction |
B1690/15 | Door Side Airbag Sensor RH Malfunction |
DESCRIPTION
The rear airbag sensor RH and No. 2 side airbag sensor assembly RH consists of a safing sensor, diagnostic circuit, lateral deceleration sensor, etc.
If the airbag sensor assembly receives signals from the lateral deceleration sensor, it determines whether the SRS should be activated.
DTC B1630/23 is stored when a malfunction is detected in the rear airbag sensor RH circuit.
DTC B1690/15 is stored when a malfunction is detected in the No. 2 side airbag sensor assembly RH circuit.
