DTC B1623/81: Side Airbag Sensor Assembly RH Initialization Incomplete: Description

The circuit for the side collision sensor RH (to determine deployment of the curtain shield airbag RH) is composed of the center airbag sensor assembly and side airbag sensor RH (for rear side).

The side airbag sensor RH (for rear side) detects impacts to the vehicle and sends signals to the center airbag sensor assembly to determine if the airbag should be deployed.

DTC B1623/81 is recorded when a malfunction is detected in the circuit for the side collision sensor RH (to determine deployment of the curtain shield airbag RH).

DTC No.	DTC Detection Condition	Trouble Area
B1623/81	When one of following conditions is met: The center airbag sensor assembly receives a line short circuit signal, an open circuit signal, a short circuit to ground signal or a short circuit to B+ signal in the circuit for the side collision sensor RH (to determine deployment of the curtain shield airbag RH) for 2 seconds.
