DTC B1786 Front Occupant Classification Sensor RH Collision Detection
DESCRIPTION
DTC B1786 is output when the occupant classification ECU receives a collision detection signal sent by the front occupant classification sensor RH if 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 "Zero point calibration" and "Sensitivity check".
Therefore, if DTC B1786 is output, first perform "Zero point calibration" and "Sensitivity check".

INSPECTION PROCEDURE
1 PERFORM ZERO POINT CALIBRATION
OK: "COMPLETED" is displayed.
2 PERFORM SENSITIVITY CHECK
Standard value: 27 to 33 kg (59.52 to 72.75 lb)
3 CHECK DTC
OK: DTC B1786 is not output.
HINT: Codes other than DTC B1786 may be output at this time, but they are not related to this check.
4 REPLACE FRONT SEAT ASSEMBLY RH
HINT: Perform the inspection using parts from a normal vehicle if possible.
5 PERFORM ZERO POINT CALIBRATION
OK: "COMPLETED" is displayed.
6 PERFORM SENSITIVITY CHECK
Standard value: 27 to 33 kg (59.52 to 72.75 lb)
7 CHECK DTC
HINT: First clear DTCs stored in the occupant classification ECU and then in the center airbag sensor assembly.
OK: DTC B1786 is not output.
HINT: Codes other than DTC B1786 may be output at this time, but they are not related to this check
8 REPLACE OCCUPANT CLASSIFICATION ECU
9 PERFORM ZERO POINT CALIBRATION
OK: "COMPLETED" is displayed.
10 PERFORM SENSITIVITY CHECK
Standard value: 27 to 33 kg (59.52 to 72.75 lb)
