DTC B1786: Front Occupant Classification Sensor RH Collision Detection: Description

WARNING: This page is about a different variant/trim than selected.

DTC B1786 is stored when the occupant detection ECU receives a collision detection signal sent by the front occupant classification sensor RH if an accident occurs.

DTC B1786 is also stored when the front seat assembly RH is subjected to a strong impact, even if an actual accident does not occur.

If the vehicle was not in a collision, but the occupant detection ECU receives a collision detection signal and stores DTC B1786, the DTC can be cleared by performing Zero Point Calibration and Sensitivity Check.

Therefore, if DTC B1786 is output, first perform Zero Point Calibration and Sensitivity Check.
