Check ur blinking light, it differs by code....

I just let mine blink :p

I would also like to have airbags. If I had the choice of no light but no air bags or air bags and a light, id go with airbags. Would Nissan be able to reset it for me?

I looked through the SR and SRC sections of the 2009 FSM and can't find any details on the "Occupant Classification System Seat Sensor Mat". :(

SRC-15 - SRC-17 shows what the different blinks mean.

SRC-17 tells how to clear errors once a malfunction is fixed - turn the car off and then back on.

SRC-157 (Wiring Diagram - SRS AIR BAG CONTROL SYSTEM)
Occupant Classification System Control Unit terminals 4 and 2 connect to Air Bag Diagnosis Sensor Unit terminals 1 and 26, respectively.
Terminals 4/1 through connector B201(Red)/M117(LG) pin 6.
Terminals 2/26 show no connector
Occupant Classification System Control Unit terminal 5 is ground through connector B202.

Not trying to highjack the thread, but what is the best way to disable the passenger side front airbag. I need to have a child seat in the car for emergencies. So it is crucial for the airbag to be off. I know the car has the automatic sensors, but I notice the light goes on and off when my 20lbs dog gets on it. I just want to make sure the sensor doesnt come back on when I need it to be off! Should I just pull the airbag fuse and call it a day? Also does hte light come on after you plug the fuse back in?

Thanks

cossie, just disconnect the air bag weight sensor and side air bad connector, it will disable it. Later when u want it back, just connect it and do the SRS reset procedure takes few seconds only.

Just an update on this. I'm working on soldering test leads onto the terminals at the moment. Also I have a 12V power supply showing up tomorrow for testing this out. And before anyone criticizes my soldering job, this is the first time I've ever soldered in my life so it's been a learning process.

Test leads done and 12V power supply hooked up. Let the testing begin. :tup:

If you can get this to work I would pay for it! Hopefully there's some way to trick the system to have the airbags on so i can finally install recaros :happydance:

you should be able to read resistance on each point and replicate accordingly. I would guess U need to get X amount of those dots to "turn on" or have same resistance across X amount and it will turn the air bag on.

I never went this far as to tear down the pad but this is a good direction!

My guess is that it counts the number of switches made, but resistance is a good possibility.

Anymore updates Gomer? Awesome work thus far, thanks!

Been super busy the last few weeks getting the car ready for AutoX season. Unfortunately this project has taken a backseat so far. Hopefully I'll be able to get back into it in the next couple weeks.

Wow, good progress gomer, be interesting to see if you can fake it out. I have the weight sensor sitting under the pad of the fake Bride seat in my passenger side, but it has never worked correctly, and pretty much always ends up disabling the airbag.

Design Complaint (against Nissan and whoever else does them like this): Based on reading the manual, what I know about how the system works (stock) is this: that sensor module is supposed to look at the pattern of its inputs (I'm not sure if they're just switches, or each one has a variable pressure value) and classify the seat's contents into one of three categories: 1) Nobody/nothing significant in the seat, airbag off 2) Child in seat, airbag off 3) Adult in seat, airbag on. There's only a single status indicator light, which lights up as to say "Hey the passenger airbag is disabled for child safety", which is option (2) above. That status light is off in both conditions 1 and 3. Given that there's some analog real-world variability to the situation (e.g. an adult with their weight distributed strangely at the edges due to body shape or posture), it's a really bad design flaw that the system doesn't tell you the difference between "no airbag because nobody's there" and "airbag on because an adult's sitting there". Hopefully in pristine stock state those two things are so different that it virtually never gets the distinction wrong, but how would you ever know?

And of course, if you're trying to make it work with another seat (and you know, seats are reasonable aftermarket options even just for comfort...), and all you've got to work with is that indicator light, you *really* have no idea whether it's working right just because the light stayed blacked out when an adult sat down, because again that could mean either of two conditions (and either airbag on for adult or off for "not sensing any real passenger").

I really wish there was option for a simple switch for airbag on/off. I get that they want things to be automatic because people will forget the switch, but the whole thing (not just Nissan's design, but the whole way that airbags work and the safety data on them) smells of poor decisions/design when it all gets this complicated on the tradeoffs. At the very least, they could've made the airbag off light also light up when it detect nobody/nothing, and only have the light turn off when it detects an adult and enables the airbag. At least then you'd know for sure what was going on.

I don't care much anymore, personally, because within a few months I'll be stripping out all the airbag system and doing a cage and harnesses anyways :P

Bump for any progress on this.
