Coffee, Back Seat and SRS Light
So I decided to get coffee for everyone at the office. I put two "Grande" cups of coffee in the back cup holders. One cup fell out and the entire thing dumped on my back seat (drivers side) As soon as I stopped I got a towel, pulled the rear seat latch and cleaned up all the coffee that dripped underneath. What a mess. I didn't think anything of it after that and went inside.
Now after starting the car I have and SRS light and malfunction error.
So...what have I shorted out back there and what's this going to cost
Anything I can check or try before heading down to the stealership? I can understand the front seats but what's in the back that could cause an SRS error?

You might have shorted out the "child seat sensor". Unfortunately, stealerships will charge you $1K+ to replace this module. Indy shops with certified techs will usually charge half or less. But if you're really handy, there's a short DIY on this posted here around a year ago.

I'll take a look at the DIY and see what we can't do.
There is at least a positive out of this. I was looking under the seats checking to make sure there wasn't any loose wires. While looking under my passenger seat I noticed one of the cables had gotten jammed under the seat. I plugged it in and what do you know...the heating button works on my passenger seat. (It's been broken since I purchased the car) seat heats up with no issues. Nice
(not sure how I over looked it before)

Lizard thanks. I was referring to Chedeng88 about the child sensors.
I'll give the seat belt tighteners a clean though it doesn't appear any coffee got on them. I'll have to call around and see if there is an indie close by that has the star system on hand.
@all-all I'm not sure there are is an "air bag" reset tool. Could you provide a link to this device.

There are no child seat sensors in the rear because there is no airbag to deploy on the child, but the buckle could have gotten shorted and caused the fault. That's what happened in my gfs civic.
