The B1651 does no come up as a valid code i have B156

This B1786


SUPPLEMENTAL RESTRAINT SYSTEM: OCCUPANT CLASSIFICATION SYSTEM: B1785: Front Occupant Classification Sensor LH Collision DetectionDTC B1785 - Front Occupant Classification Sensor LH Collision DetectionDESCRIPTIONDTC B1785 is output when the occupant classification ECU receives a collision detection signal sent by the front occupant classification sensor LH if an accident occurs.
DTC B1785 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 B1785 can be cleared by "zero point calibration" and "sensitivity check".
Therefore, if DTC B1785 is output, first perform "zero point calibration" and "sensitivity check".HINT: When DTC B1650/32 is detected as a result of troubleshooting for the AIRBAG SYSTEM, check the DTCs stored in the occupant classification ECU. When DTC B1785 is output, perform troubleshooting for the DTC.WIRING DIAGRAM
INSPECTION PROCEDUREPROCEDURE1. PERFORM ZERO POINT CALIBRATION
(a)Connect Techstream to the DLC3.
(b)Turn the ignition switch on (IG).
(c)Using Techstream, perform "zero point calibration" ( See: Restraints and Safety Systems > Programming and Relearning > Initialization).
OK:
"Zero Point calibration is complete." is displayed.
NG -- REPLACE FRONT SEAT ASSEMBLY RH
OK -- Continue to next step.
2. PERFORM SENSITIVITY CHECK
(a)Using Techstream, perform "sensitivity check" ( See: Restraints and Safety Systems > Programming and Relearning > Initialization).
Standard value:
27 to 33 kg (59.52 to 72.75 lb)
NG -- REPLACE FRONT SEAT ASSEMBLY RH
OK -- Continue to next step.
3. CHECK DTC
(a)Turn the ignition switch on (IG).
(b)Clear the DTCs stored in the occupant classification ECU ( See: Restraints and Safety Systems > Reading and Clearing Diagnostic Trouble Codes).
(c)Clear the DTCs stored in the center airbag sensor assembly ( See: Air Bag Systems > Reading and Clearing Diagnostic Trouble Codes > DTC Check / Clear).
(d)Turn the ignition switch off.
(e)Turn the ignition switch on (IG).
(f)Check the DTCs ( See: Restraints and Safety Systems > Reading and Clearing Diagnostic Trouble Codes).
OK:
DTC B1785 is not output.HINT: Codes other than DTC B1785 may be output at this time, but they are not related to this check.OK -- END
NG -- Continue to next step.
4. REPLACE FRONT SEAT ASSEMBLY RH
(a)Turn the ignition switch off.
(b)Disconnect the negative (-) terminal cable from the battery.
(c)Replace the front seat assembly RH ( See: Seats > Removal and Replacement > Removal) for power seat or ( See: Seats > Removal and Replacement > Removal) for manual seat).HINT: Perform the inspection using parts from a normal vehicle if possible.NEXT -- Continue to next step.
5. PERFORM ZERO POINT CALIBRATION
(a)Connect the negative (-) terminal cable to the battery.
(b)Connect Techstream to the DLC3.
(c)Turn the ignition switch on (IG).
(d)Using Techstream, perform "zero point calibration" ( See: Restraints and Safety Systems > Programming and Relearning > Initialization).
OK:
"Zero Point calibration is complete." is displayed.
NG -- REPLACE OCCUPANT CLASSIFICATION ECU
OK -- Continue to next step.
6. PERFORM SENSITIVITY CHECK
(a)Using Techstream, perform "sensitivity check" ( See: Restraints and Safety Systems > Programming and Relearning > Initialization).
Standard value:
27 to 33 kg (59.52 to 72.75 lb)
NG -- REPLACE OCCUPANT CLASSIFICATION ECU
OK -- Continue to next step.
7. CHECK DTC
(a)Turn the ignition switch on (IG).
(b)Clear the DTCs stored in the occupant classification ECU ( See: Restraints and Safety Systems > Reading and Clearing Diagnostic Trouble Codes).
(c)Clear the DTCs stored in the center airbag sensor assembly ( See: Air Bag Systems > Reading and Clearing Diagnostic Trouble Codes > DTC Check / Clear).
(d)Turn the ignition switch off.
(e)Turn the ignition switch on (IG).
(f)Check the DTCs ( See: Restraints and Safety Systems > Reading and Clearing Diagnostic Trouble Codes).
OK:
DTC B1785 is not output.HINT: Codes other than DTC B1785 may be output at this time, but they are not related to this check.OK -- END
NG -- Continue to next step.
8. REPLACE OCCUPANT CLASSIFICATION ECU
(a)Turn the ignition switch off.
(b)Disconnect the negative (-) terminal cable from the battery.
(c)Replace the occupant classification ECU ( See: Seat Occupant Sensor > Removal and Replacement > Removal).
NEXT -- Continue to next step.
9. PERFORM ZERO POINT CALIBRATION
(a)Connect the negative (-) terminal cable to the battery.
(b)Connect Techstream to the DLC3.
(c)Turn the ignition switch on (IG).
(d)Using Techstream, perform "zero point calibration" ( See: Restraints and Safety Systems > Programming and Relearning > Initialization).
OK:
"Zero Point calibration is complete." is displayed.
NEXT -- Continue to next step.
10. PERFORM SENSITIVITY CHECK
(a)Using Techstream, perform "sensitivity check" ( See: Restraints and Safety Systems > Programming and Relearning > Initialization).
Standard value:
27 to 33 kg (59.52 to 72.75 lb)
