Error Code B1312 is a failure of the Passenger Seat Airbag Sensor. There is a sensor in the bottom seat cushion that detects if someone is actually sitting in the seat and controls the passenger side airbags. This sensor seems to be prone to failure and is not available as a separate replacement part. You have to replace the whole seat at a cost of over $2000. This issue has been covered in the forum before:

I believe the entire Air Bag System is deactivated when this sensor fails. You should check that the wiring connector under the seat is properly connected, I have heard that if it comes loose, the error code will appear.

If you are in the USA, I would make a complaint to the NHTSA. Suzuki is ignoring this issue and forcing owners to pay for repairs. Its a major safety problem that they should correct.

We don't have this sensor in Australia.

Perhaps there is a way to stop the BCM testing for it..

I was thinking the same thing. I think it depends on the type of air bags the GV uses.

If the seat sensor simply measures if someone is seating in the seat, then in theory it should be possible to jumper the connection and fool the system into thinking there is always someone there. The passenger airbags would deploy in an accident even if the seat was empty.

If the sensor measures if someone is seating in the seat and the weight of the person, then it probably isn't possible to fool the system. Some airbags are "dual-stage" and deploy at different intensities, depending on the size of the passenger.

I think the GV uses single-stage airbags, that don't take into consideration the size of the person. Although, the 10 channel airbag system as used in NA has an "Occupancy Classification ECM" which might be weighing the passenger. The is no mention of the seat sensor in the factory manual anywhere, nor the error code B1312, so I can't confirm its mode of operation.

In general it is a really bad idea to mess with the air bag system. A slight miscue will set them off accidently or disable them so they don't fire when you need them. Probably the best, safest solution is to replace the seat or get Suzuki to replace the seat.

I'm really sure the Canadian GV has a sensor that determines seat occupant weight for the front passenger seat.

Oh, and $2000 would easily be enough for me to sue them in Small Claims Court.

They are dual stage and there is a sensor mat in the seat that measures both weight/size and if someone is there or not all together. All cars have dual stage air bags now. The seat can be warrantied under the bumper to bumper warranty. After that you are on your own. The sensor is only damaged from sharp objects or liquids spilt in the seat.

There is no way to "trick" the SDM. There is way more to the system then a paperclip would solve!

There is always a way :-)

You could but a SDM from down under :-) haha..

No seriously, don't think about disabling it, Annfan is right.. It's too dangerous to mess with stuff like that.

I agree with that and by the way rescue squads are very anxious for spontaneous airbag incidents
