Carpet Cleaned but SRS Airbag Light On Now - iCarsoft i980 Clears Code

Be Warned – If you disconnect the passenger side seat air bag connectors (due to “special seat weight module”) without disconnecting the battery this will happen.

Bought the car sight unseen and had delivered (from 700 miles away) a couple months ago and have been very pleased except whoever had leased the car let either a dog or cat ride and pee in it, a bunch.
The car stunk like a wet dog whenever it was damp outside or the inside of the car got very hot.
I had enough of the sink and took all the carpet out, soaked and washed it in Clorox/Detergent water mix, rinsed and dried in hot sun for 2 days.
Put everything back together and the Airbag light was on.
I figured I didn’t connect something or pulled a wire but nope……found the “soft code” Mercedes Star diagnostic horror stories about the SRS Airbag system in our Smart cars.
(Note – I had previously disconnected the driver side seat air bag connectors which turned on the light but when reconnected the light went back out…..did this figuring out how to install a magnet on proximity switch to make the drive side seatbelt buzzer turn off.)
After reading similar issues on this forum, I ordered a used iCarsoft i980 scanner ($95) which reset the Airbag light.
Thanks smartcar forum.

Thanks for the photos - I've been looking for a good photo of the battery-pack disabling "pyrofuse" unit under the driver's side seat. Kane at evilution has asked me for a picture and I told him I was not interested in the work involved unless I had to do it to repair something else after the warranty is expired, so your post is uncannily at the right time.

And also, can you provide some details on how you disabled that annoying seat belt buzzer?

(There is a magnet in the latch and when the seat belt is inserted and latched that magent moves close to the switch and tells the car the seat belt is on so the buzzer shuts up.) To get around this, remove the proximity switch out of the driver's side seat belt latch...it just slides out. The get a strong small magnet and tape it to the little small round end of the switch...you have to orient the magent with the correct polarity or it want work....just turn the magent over if it doens't turn the buzzer off the first time. See picture.


Also included a couple more pictures of what is under the carpet under the seats.

Could you also just remove the switch and connect the wire ends - or leave open, depending on what the "belt fastened" switch state is?

I'm reluctant to do any even minor mods for one more year (when the warranty expires). Shame it is not as easy as my Subaru - just turn the key switch on (but don't start the engine) , fasten and unfasten quickly 20 times in 30 seconds, turn the key switch off.

Curiously, the only mod I did do while it was a lease was to disconnect the "noisemaker" behind the grille (US DOT requirement for 2016 and newer EV's I think). Before returning the lease, (but got a reasonable offer way below the residual from the dealer so I bought it), I reconnected the noisemaker, but the noisemaker no longer makes any noise. The SAM seems to have it's tendrils around the operation of even the most superficial accessories...

I actually pulled the driver's seat out of the car and studied the wiring to figure out the proximity switch in the seat belt latch.
It is very very easy to do and nothing you can't put back just like original in 3 minutes.
Just remove the switch from the seat belt latch....switch will just slide out with a little screwdriver help.
Get a small strong magnet.
Put the magnet on the round part of the switch and tape it there.....like the picture above.
If the buzzer goea off or the light in the dash is still there just turn the magent over and try again.


BTW - the first "mod" I did was also unplug the noisemaker.....I don't plan on running over any pedestrains so don't see the need....besides one of the reasons I got the car was to be able to drive around not making any noise.

Oh my, sure didn't see that one coming...

What will it be next, Maytag washing machines?

Seriously, look forward to some of your ED discoveries.

Just my .02 but the simplest way to disable the seatbelt buzzer is to buckle the seatbelt....
