so is this the expensive but easy solution to the weight sensor diy? and do you still need a resistor for the airbag with this?

The unit is (probably*) just a resistor that is "tuned" to the resistance of the seat sensor when it is occupied. The resistor values I've seen used in the DIYs on this site are to emulate an empty seat. I haven't looked at the FSM in a while but, IIRC, the un/occupied values are in the FSM.

*Couldn't find a schematic of the unit but it's replacing a resistive element.

Is there any disadvantage to always having the seat sensor occupied? That would just mean that in the case of an accident, the passenger air bags would deploy even with no passenger, correct?

It's been a while since I look at the details in the FSM (link in my sig) but IIRC, you are correct.

If I were using the vehicle on the track, I'd go with the unoccupied option (assuming no passenger). On the street, occupied (just in case there was a passenger). YMMV.

I’ve also had good success with the airbag 360 module. Only problem is passenger belt light is constantly illuminated unless seatbelt is clicked

Couldn't you get around that with a resistor in the seat belt harness?

Maybe a more experienced member could answer but honestly I’m not sure. I just live with the light when I don’t have a passenger. The resistors in the airbag plug have functioned flawless for me with no light

do you still have the white plug from the seat belt plugged into the connector coming out the floor?

If so just disconnect it and the light should go away

Thanks for the suggestion! I didn’t know it was that easy. I originally connected it back up thinking it would throw an error if the harness wasn’t plugged in

Just installed my racing seats with the resistor fix, airbag360 emulator then did the airbag light fix and good to go. Thanks all.

Good afternoon.

And I tried this with my 370z, I put 4.7ohm 1 / 2w resistors and the passenger presence sensor, the error does not appear for a while, but at the same time the airbag light flashes again.

When making a diagnosis with ecutek, I only get failure in the passenger airbag.

I have the original belt support installed only on the passenger, the driver does not have the OEM anchor.

Do you know what can happen?

Now what would be really slick would be to put the resistor on a switch into the seat sensor circuit. You could enable/disable the airbag at will. You could even drop the switch into the blank 3 (assuming you have the blanks to begin with)
