DTC B1693/81: Door Side Airbag Sensor RH Initialization Incomplete; DTC B1698/82: Door Side Airbag Sensor LH Initialization Incomplete: Description

The circuit for the side collision sensor LH or RH (to determine deployment of the front seat airbag LH or RH and curtain shield airbag LH or RH) is composed of the center airbag sensor, rear airbag sensor LH or RH, side airbag sensor LH or RH and door side airbag sensor.

The rear airbag sensor LH or RH, side airbag sensor and door side airbag sensor LH or RH detect impacts to the vehicle and send signals to the center airbag sensor to determine if the airbag should be deployed.

DTC B1693/81 or B1698/82 is stored when a malfunction is detected in the circuit for the side collision sensor LH or RH (to determine deployment of the front seat airbag LH or RH and curtain shield airbag LH or RH).

DTC Code	DTC Detection Condition	Trouble Area
B1693/81	One of the following conditions is met: The center airbag sensor detects a line short circuit signal, open circuit signal, short circuit to ground signal or short circuit to B+ signal in the circuit for the side collision sensor RH (to determine deployment of the front seat airbag RH and curtain shield airbag RH) for 2 seconds. A door side airbag sensor RH malfunction. A rear airbag sensor RH malfunction. A center airbag sensor malfunction.
