Description
Dtc b1786 is output when the occupant classification ecu receives a collision detection signal sent by the front occupant classification sensor rh when an accident occurs.
Dtc b1786 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 occupant classification ecu outputs a collision detection signal, even if the vehicle is not in a collision, dtc b1786 can be cleared by performing the zero point calibration and sensitivity check.
Therefore, when dtc b1786 is output, first perform the zero point calibration and sensitivity check.

Inspection procedure
Ok: completed is displayed.
Standard value: 27 to 33 kg (59.52 To 72.75 Lb)
Hint:
First clear dtcs stored in the occupant classification ecu and then in the center airbag sensor.
Ok: dtc b1786 is not output.
Hint:
Dtcs other than dtc b1786 may be output at this time, but they are not related to this check.
Hint:
Perform the inspection using parts from a normal vehicle if possible.
Ok: completed is displayed.
