SUPPLEMENTAL RESTRAINT SYSTEMS: OCCUPANT CLASSIFICATION SYSTEM: B1787: Rear Occupant Classification Sensor
LH Collision Detection
B1787 - Rear Occupant Classification Sensor LH Collision Detection
DESCRIPTION
DTC B1787 is stored 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 stored when the front seat assembly RH is subjected to a strong impact, even if an actual accident does not occur.
If the vehicle is not in a collision, but the occupant classification ECU outputs a collision detection signal and sets DTC B1787, the DTC can be
cleared by performing the Zero Point Calibration and Sensitivity Check.
Therefore, if DTC B1787 is output, first perform Zero Point Calibration and Sensitivity Check.
HINT
When DTC B1650/32 is detected as a result of troubleshooting for the airbag system, check the DTCs stored in the occupant
classification ECU. When DTC B1787 is output, perform troubleshooting for the DTC.
