Occupant sensor
 

I've done some searching about this but haven't found a definitive answer.

I'm installing a pair of seats in my BRZ and want to retain the stock passenger occupancy sensor. I've disassembled the stock seat and removed the pad but I can't get it to trigger the airbag on in the new seat.

Has anyone done this successfully?

Or is there some kind of bypass type of switch that allows me to manually select on or off?

Help would be greatly appreciated. Thanks

my iphone seems to have magical powers to trigger the airbag sensor when i place it on the passenger seat. so annoying.

Same here. Lol

I'm starting to think that no one running aftermarket seats has a working passenger side airbag lol.

I read one guys writeup about folding it up and stuffing it under the seat, but that's not how these sensors work. If you fold it in on itself, it throws an airbag light.

Does ANYONE have a working passenger side airbag with aftermarket seats?

Mine would work but I ended up throwing it under the carpet. We did not have the time to take apart my new EVO seat to stick the new sensor in. Basically you just need to take the seat cover off the stock seat, pull the sensor pad and then put it in the new seat and plug it in to the harness. I will eventually have it moved into the new seat.

This is what you are looking for.

I removed that pad along with the module and have it installed in the seat. It does not switch to AIRBAG ON when someone sits in the seat. I tried putting the pad under the seat, which obviously doesn't work either, and rolling it up onto itself causes the airbag warning light to trigger.

Does your passenger airbag go to ON status?

all phones that emit an electrostatic aura do this..

I put it under the seat bottom foam in my recaro pole positions. Worked just fine.

Nice!

How did you remove it from the factory seat? Just pulled that grey foamy stuff off of the cushion?

Lifted the fabric and worked it out from under there. Some of that thin grey foam came with it so I guess that's what it's glued to

Mine constantly thinks someone is in the seat. So I had to have the seatbelt chime turned off via techstream.

Known issue. It's because it is NOT weight sensitive but uses a current flow to detect. Most likely it is not your iPhone but you are charging your iPhone and the connector is in the seat. Several threads on this on here.

I can make my Droid Maxx do it at will. Insert the charging plug, lay on seat, I have a phantom passenger. Unplug, no passenger. Plug back in, lay the phone so that the charging plug is lifted off the seat and on the bolster, no passenger.

Things that are wet, or liquid can also set it off. Its similar to a touchscreen or biometric reader that uses a very low current charge to make a connection.

You learn new things everyday! Thanks for the insight!

Mine does work. Whilst I didn't do the install myself I had a chat with the guys that did, and that's how it goes.

Mine did too!

nope, Iphone has an electrostatic aura and at least the iphone 5 and 6 unplugged will trigger the sensor if it's placed around 75% of the area.. certain spots will not trigger it (sensor shown above in the thread)

Good to know, but same cause. A lot of folks think that its a weight sensor and it isn't, which is the real point in the end.

Just to add some closure to this..

I picked up a spare FR-S passenger seat base from a wrecker and removed the occupant sensor from it. Being much more careful with the ribbon cables and also when separating the grey foam off of the seat foam, i was able successfully transfer it over to my Edirb 023 without issue.

I must have damaged something during the removal of my original one, so if anyone else attempts this, be very careful.

Just wanted to revive the thread to ask these questions

Questions to follow:

1 - In order to swap my FRS to BRZ heated leather seats, I only need to swap the occupancy module from my stock seats to remove the chime?

2 - will the BRZ seats still deploy without the occupancy module swap? (Leaving in BRZ Occ module and living with the annoying chime.

3 - Leaving the occupancy seat alone and living with he chime could I use techstream to disable the chime or simply add a seatbelt on? Will the airbag still deploy?

4 - with the occupancy module stock FRS or BRZ - will either scenarios cause an airbag light?

Emulators exist for other markets, surely it can't be rocket surgery to make one.

Maybe @Beastronix could produce something?

Hell, if someone sends me a sensor I'll figure it out, if I get stuck I have an EE on staff that I could lean on.

I've added this to my potential project list. I'm stretched thin with free time at the moment, so not sure how soon I can look into it.

I can currently disable the airbag lamps, but I only do this for race prepped cars. I have no data at the moment that proves certain steps in this process actually switch the airbag deployment sensors.

Also note this is all over CAN. Defeating everything over the network is my go to, but I'm not opposed to alternatives if they are needed.

Did anyone get anything working here. I am having the same exact issue. I have taken the occupancy sensor out and I can not for the life of my get the airbag light off and the Passenger Airbag enabled. Any suggestions would be greatly appreciated. I can not place these inside the seats I have so I need some way to bypass this or somewhere to "wrap it up" and make it work and think someone is sitting there.
