SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: B1630/23: Driver Side Rear Airbag Sensor Malfunction
B1630/23 - Driver Side Rear Airbag Sensor Malfunction
DESCRIPTION
The rear airbag sensor LH consists of parts including the diagnostic circuit and the lateral deceleration sensor.
When the center airbag sensor assembly 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.
