DTC B1787 Rear Occupant Classification Sensor LH Collision Detection

DESCRIPTION

DTC Detecting Condition:

DTC B1787 is output when the occupant classification ECU receives a collision detection signal sent by the rear occupant classification sensor LH when an
accident occurs.

DTC B1787 is also output when the front seat assembly RH is subjected to a strong impact even if an actual accident does not occur.

However when the rear occupant classification sensor LH outputs a collision detection signal even if the vehicle is not in a collision DTC B1787 can be cleared by performing the zero point calibration and sensitivity check.

Therefore when DTC B1787 is output first perform the zero point calibration and sensitivity check.
