Toyota Tundra Service Manual > Occupant Classification System: Rear Occupant Classification Sensor RH Collision Detection (B1788)
DESCRIPTION DTC B1788 is set when the occupant classification ECU receives a collision detection signal, which is sent by the occupant detection sensor rear RH when an accident occurs. DTC B1788 is also set when the front seat frame with adjuster RH is subjected to a strong impact, even if an actual ...
