AIRBAG SYSTEM, Diagnostic DTC:B1690/15, B1692/81

DTC Code DTC Name
B1690/15 Driver Side Door Side Airbag Sensor Malfunction
B1692/81 Lost Communication with Driver Side Door Side Airbag Sensor

DESCRIPTION

for DTC B1690/15:

The driver side - side airbag sensor (for front side) consists of the safing sensor, the diagnostic circuit, the lateral deceleration sensor, etc.

If the center airbag sensor assembly receives signals from the lateral deceleration sensor, it determines whether the SRS should be activated.

DTC B1690/15 is recorded when a malfunction is detected in the driver side - side airbag sensor (for front side) circuit.

for DTC B1692/81:

The circuit for the driver side - side collision sensor (to determine deployment of the front seat side airbag (driver side) and curtain shield airbag (driver side)*1) is composed of the center airbag sensor assembly, driver side - side airbag sensor (for front side) and driver side - side airbag sensor (for rear side)*1.

The driver side - side airbag sensor (for front side) and driver side - side airbag sensor (for rear side)*1 detect impacts to the vehicle and send signals to the center airbag sensor assembly to determine if the airbag should be deployed.

DTC B1692/81 is recorded when a malfunction is detected in the circuit for the driver side - side collision sensor (for front side) (to determine deployment of the front seat side airbag (driver side) and curtain shield airbag (driver side)*1).
