DTC B1785: Front Occupant Classification Sensor LH Collision Detection [11/2021 - 10/2023]: Description
DTC B1785 is stored when the occupant detection ECU receives a collision detection signal sent by the front occupant classification sensor LH in the case of an accident.
DTC B1785 is also stored when the front seat assembly RH is subjected to a strong impact, even if an actual accident did not occur.
If the vehicle was not in a collision, but the occupant detection ECU receives a collision detection signal and stores DTC B1785, the DTC can be cleared by performing zero point calibration.
Therefore, if DTC B1785 is output, first perform zero point calibration.
