B1787

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 if 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 occupant classification ECU outputs a collision detection signal, even if the vehicle is not in a collision, DTC B1787 can be cleared by "zero point calibration" and "sensitivity check".

Therefore, if DTC B1787 is output, first perform "zero point calibration" and "sensitivity check".
