DTC B1690/15: Door Side Airbag Sensor RH Malfunction; DTC B1692/81: Lost Communication with Door Side Airbag Sensor RH: Description

for DTC B1690/15:

The side airbag sensor RH (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 side airbag sensor RH (for front side) circuit.

for DTC B1692/81:

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

The side airbag sensor RH (for front side) and side airbag sensor RH (for rear side) 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 side collision sensor RH (for front side) (to determine deployment of the front seat side airbag RH and curtain shield airbag RH).
