DTC B1788 Rear Occupant Classification Sensor RH Collision Detection

DESCRIPTION

DTC Detection Condition:

DTC B1788 is output when the occupant classification ECU receives a collision detection signal sent by the rear occupant classification sensor RH when an accident occurs.

DTC B1788 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 RH outputs a collision detection signal even if the vehicle is not in a collision DTC B1788 can be cleared by performing the zero point calibration and sensitivity check.

Therefore when DTC B1788 is output first perform the zero point calibration and sensitivity check.
