Description
Dtc b1787 is output when the occupant classification ecu receives a collision detection signal sent by the rear occupant classification sensor lh when an accident occurs.
Dtc b1787 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 b1787 can be cleared by performing the zero point calibration and sensitivity check.
Therefore, when dtc b1787 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 b1787 is not output.
Hint:
Dtcs other than dtc b1787 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.

Removal
Hint:
Use the same procedures for the rh side and lh side.
The procedures listed below are for the lh side.
Disconnect cable from negative battery
terminal
Caution:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and ...
Lost communication with front passenger side - side airbag sensor assembly
Description
The side airbag sensor rh consists of parts including the diagnostic circuit
and the lateral deceleration
sensor.
When the center airbag sensor receives signals from the lateral deceleration
sensor, it determines
whether or not the srs should be activated.
