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

DTC B1786 is stored when the occupant classification 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 is not in a collision, but the occupant classification ECU outputs a collision detection signal and sets 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.

HINT: 

When DTC B1650/32 is detected as a result of troubleshooting for the airbag system, check the DTCs stored in the occupant classification ECU. When DTC B1786 is output, perform troubleshooting for the DTC.
