Rear Occupant Classification Sensor RH Collision Detection (B1788)
DESCRIPTION
DTC B1788 is stored when the occupant classification ECU receives a collision
detection signal, which is sent by the occupant classification sensor rear RH when
an accident occurs.
DTC B1788 is also stored when the separate type front seat cu ...
