DTC |
B1787 |
Rear Occupant Classification Sensor LH Collision Detection |
DESCRIPTION
DTC B1787 is stored when the occupant detection ECU receives a collision detection signal sent by the rear occupant classification sensor LH in the case of an accident.
DTC B1787 is also stored when the front seat assembly RH is subjected to a strong impact, even if an actual accident did not occur.
If the vehicle was not in a collision, but the occupant detection ECU receives a collision detection signal and stores DTC B1787, the DTC can be cleared by performing zero point calibration. Therefore, if DTC B1787 is output, first perform zero point calibration.
