If the vehicle has been in a rear end collision, expect this. If not, it just may need to have the Occ Class Sys reset. Toyota Dealer only.

    Is there any documented information about the B1650 code after a rear end collision? I was just irear ended in my 07 Prius and the SRS light has come on. The shop I took it to diagnosed it, but the other drivers insurance will not pay to have the problem fixed saying there is no proof. The Toyota dealership told me the diagnoses will not show the cause. Any help whould be appreciated.

SOURCE: DTC B1650 occupant classification system

If it is like a Chrysler, you will need to go to the dealer and have them redo the OCS. This has to do with the passenger airbag system and how much force it will send the air bag with.

2014. What are the probable causes of DTC B1650?


go google and type in--- fault code b1650 on toyota 2014 model--and there is a site --www.toyotapart.com which has a pdf down load and explanation of the fault
it concerns the passenger initialization of the air bag systems and how they are locked out if there are no passengers
it requires a special procedure to reset it
it covers recalls as well
I would suggest that you down load the pdf version, study it then take the car to a service dealer senter and have it fixed under warranty

Where is passenger side air bag relay 2007 MKZ


There is no relay for the passenger side air bag . What seams to be the trouble ? There is possibly a code set in the air bag control module .
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants, in addition to that provided by the 3-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles are also equipped with driver and front passenger safety belt retractor pretensioners. These vehicles can also be equipped with optional side air curtains that deploy from the A-pillar to the C-pillar upon a side impact. Vehicles with optional side air curtains are also equipped with seat side air bag modules in the front seats.
Side air curtains deploy from the headliner, protecting the first and second row outboard occupants during a side impact. Seat side air bag modules deploy from the outboard front seat backrest upon a side impact. In addition, a front impact severity sensor is mounted to the lower radiator support, a seat position sensor is mounted to the driver seat and a usage detection switch is added to the front driver and passenger outboard buckles. If equipped with optional side air curtain modules and seat side air bag modules, there are an additional 4 side impact sensors.
Vehicles are also equipped with an occupant classification sensor (OCS) system as part of the front passenger seat. The OCS system includes 2 OCS rails and an OCS module.
Passenger Air Bag Deactivation (PAD) Indicator
The passenger air bag deactivation (PAD) indicator is a visual indicator used to inform the front seat occupants of the passenger air bag deactivation state. The PAD indicator is a stand-alone lamp installed into the vehicle instrument panel in a position visible to each front seat occupant.
The restraints control module (RCM) controls the state of the PAD indicator through a direct hardwire connection, based on information provided by the occupant classification sensor (OCS) system. The PAD indicator is lit to indicate the passenger air bag module is disabled. An exemption to this is when the front passenger seat is determined to be empty and passenger safety belt buckle unbuckled, and therefore indication of a deactivated passenger air bag module is not necessary. In all other cases, the PAD indicator is unlit when the passenger air bag module is enabled.
When the ignition switch is in the ON position, the PAD indicator prove-out period is initiated by the RCM. The RCM briefly activates the PAD indicator to prove-out the indicator function and verify to the front occupants correct functional operation of the PAD indicator.
The PAD indicator will be lit/unlit within 1.0 to 1.5 seconds of a change of state from the OCS system.
When an OCS system fault is present, the RCM defaults the passenger air bag module to the last valid state received from the OCS system until the ignition switch is turned OFF. If the OCS system fault is still present when the ignition switch is turned ON, the RCM defaults the passenger air bag module to enabled regardless of the size of occupant in the front passenger seat. The PAD indicator will be unlit. For information on the OCS system, refer to Occupant Classification Sensor System in this section.
The following table indicates the passenger air bag status and the PAD indicator status based the size of the front outboard passenger occupant.

Suzuki forenza 2005 what is b1446 mean


short answer, Occupant controls failure. Passenger seat.

medium answer , air bags ,seat sensors and or seat belt systems failure.

Long answer.

no engine of the 5, are stated. nor country,



This is covered 100% in the book called FSM.

the factory service manual, on all cars. they have one

read it.? or at alldata.com and here

just $4 to read it.

https://suzukipitstopplus.com/



my best guess, is air bags (and ARE a danger to all mechanics that fail to read the FSM warnings, !!!)

the module is not communicating , due to power loss is the clue.

in case you dont know, error codes never tell you what part is bad

it at the least tells you what signal is dead, bad or a sensor not responding

what a tech,does, is do more test to ISOLATE the true cause.

others guess, and go broke fast $$$$$$



the Forenza is this Suzuki with Daewoo body and GM enigne,

are real pistol to work on,,,

rule 2, is the code is unique to suzuki, no other cars.

B1446 (i roll dice and guess)

2.0L engine, automatic.

out of FSM it states

but what does , OC mean,

its short, (not nice huh)

for

e Occupant Classification System (OCS)











Trouble Code: B1446 (2.0L L4 VIN - Auto)

OC Passenger Short to Power (Battery) or No Response








Trouble Code Conditions:

The OC sensor wiring is shorted to the battery wiring

Possible Causes:



  • Circuit


  • Sensor




OC rules before PLAYING around. a short excerpt.




If the vehicle is equipped with the Occupant Classification System (OCS), do not connect the battery negative cable before performing the OCS Verification Test using the scan tool and the appropriate diagnostic information. Personal injury or death may result if the system test is not performed properly.

Never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace one, then perform the Airbag System test before replacing the other.

Both the ORC and the OCM store Occupant Classification System (OCS) calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an irreversible fault will be set in both modules and the OCS may malfunction and cause personal injury or death.

If equipped with OCS, the Seat Weight Sensor is a sensitive, calibrated unit and must be handled carefully. Do not drop or handle roughly. If dropped or damaged, replace with another sensor. Failure to do so may result in occupant injury or death.

If equipped with OCS, the front passenger seat must be handled carefully as well. When removing the seat, be careful when setting on floor not to drop. If dropped, the sensor may be inoperative, could result in occupant injury, or possibly death.

If equipped with OCS, when the passenger front seat is on the floor, no one should sit in the front passenger seat. This uneven force may damage the sensing ability of the seat weight sensors. If sat on and damaged, the sensor may be inoperative, could result in occupant injury, or possibly death.

Replacing severe


cebd8d08-0b93-4be4-a8ba-b0eb7c57df3a.jpgCheck connections under passenger seat.
The SRSCM sets DTC B1322 if
there is any fault in Weight Classification System.



In contrast to the initial
one-stage airbag systems, newer restraint systems involve complex logic to
select, or alternatively suppress, various levels of safety system deployment.


Inherent to an advanced
Restraint System is the ability to discern information regarding passenger
occupancy.


It is intended that these
inputs be provided through the weight measuring OC system.


The object of such safety
system is to reduce the risk and level of injuries by automatically adapting the
airbag(s) and seat belt pretensioner to the driving status of the vehicle, its
occupants, and the crash severity.


The current OC system covered
in this specification continually senses and classifies the front passenger side
seat.


OCS is utilizing a robust
weight measuring technology. Thus, if any of the following conditions occur,
'command zero' and 'accuracy check' should be performed


The weight classification ECU
or any of the sensors is replaced.


The vehicle is brought to the
repair shop due to an accident or a crash even though the severity seems to be
minor.


The passenger airbag ON
indicator is off (not illuminated) when the passenger seat is not
occupied.


The passenger airbag ON
indicator is delayed more than 10 seconds before turning off when an adult
passenger is seated in the right front seat.


The passenger seat is removed
from the vehicle and re-assembled.


Any accessories (side table,
seatback table and seat cover, etc) are replaced or installed.
