DTC B1693/81 Driver Side Door Side Airbag Sensor Initialization Incomplete

DESCRIPTION

Detection Condition (Part 1):

Detection Condition (Part 2):

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

The side airbag sensor LH or RH 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 B1623/81 or B1628/82 is recorded when a malfunction is detected in the circuit for the side collision sensor LH or RH (to determine deployment of the front seat side airbag LH or RH and curtain shield airbag LH or RH).

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

INSPECTION PROCEDURE

NOTE:
- When disconnecting the cable from the negative (-) battery terminal while performing repairs, some systems need to be initialized after the cable is reconnected.
- After the ignition switch is turned OFF, the navigation system requires approximately 90 seconds to record various types of memory and settings. As a result, after turning the ignition switch OFF, wait 90 seconds or more before disconnecting the cable from the negative (-) battery terminal.
