A month ago I had a gallon of milk leak in my passenger seat of my 2008 Titan. I freaked out having had kids with sippy cups in other cars I know the funk that spilled milk will make. So I grabbed a towel and pressed soaked up as much as I could and then took a water bottle and drenched the seat in the spill area then pressed that out with the towel.

Well I'm happy to say I haven't smelled the funk but the next day after this happened the airbag light came on and I knew right away the seat sensor must've got wet. I hoped it would dry out, but now weeks later it still is flashing. I've tried resetting it multiple times, it'll stay off for around 10 to 20 minutes of driving then come back on.

Any ideas on a possible fix?

Got any black electrical tape?

If you can't see it, it's as good as fixed.

With the obnoxious way it blinks rapidly and continously i have begun to seriously consider this option. Apparently just being on and red isn't enough for Nissan gotta make it as obnoxious as possible.

Unfortunately that is the best answer I have as airbag systems are incredibly annoying do to their safety nature. It seems like it doesn't take much for the system to throw an error and shut the system down.

Disconnect battery for 15 minutes "MINIMUM" and see if you can remove the sensor from underneath in order to dry it out. Reinstall, and then reconnect battery. Caveat, I have no idea exactly where this sensor is or how it is mounted, but would certainly find out. If removable, might be cheap to replace.

So I took the seat out of the truck. Looking at everything underneath it looks like the water would have drained out the back away from the electronics under there. Their are two items, the "occupant position sensor" which is hooked to a bladder in the seat and the "Occupant Classification Control Unit".

I was surprised to find out the seat bladder is oil filled I thought maybe some how water had gotten into the sensor via the bladder but obviously that couldn't have happen.

So I'm at a lost, everything appeared dry and looking at where the cut outs are in the steel for the seat the water should have drained safely away from the electronics.

I can get it into diagnostic mode by turning the ignition on and off 3 times in a row, and it gives me a simple code that repeats. The light comes on for 2 seconds and then goes off for 1 second then on for 2 seconds, then off for 1 second etc..

I looked that code up in the service manual and basically it is the most generic code you can get. All other codes will point the finger at something but this code... It said that their was some kind of intermittent problem and too ask the customer more questions to try to figure out what exactly the problem might be... Dumbest thing ever. I'm wondering if I could get more info with the truck connected to the consult III diagnostic tool at the dealership, but I don't wanna spend 70$ to find out that I can't.

I'm beginning to wonder if the seat is actually the problem or was the timing just coincidental?
