B1786

DTC B1786 Front Occupant Classification Sensor RH Collision Detection

DESCRIPTION

DTC Detection Condition:

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

However, when the occupant classification ECU outputs a collision detection signal, even if the vehicle is not in a collision, DTC B1786 can be cleared by "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 "AIRBAG SYSTEM", check the DTCs stored in the occupant classification ECU. When DTC B1786 is output, perform troubleshooting for the DTC.
