B1785

DTC B1785 Front Occupant Classification Sensor LH Collision Detection

DESCRIPTION

DTC Detection Condition:

DTC B1785 is output when the occupant classification ECU receives a collision detection signal sent by the front occupant classification sensor LH when an accident occurs.

DTC B1785 is also output when the front seat 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 B1785 can be cleared by performing the zero point calibration and sensitivity check.

Therefore, when DTC B1785 is output, first perform the zero point calibration and sensitivity check.
