Going wheeling this weekend for the first time in my truck and have heard to many horror stories about the side airbags. looking at the fuse box, I only see 1 fuse for SIR (fuse 27). Is this the correct one for my 08 h3.

EDIT: got home and pulled the fuse, airbag light is on. So 27 is the correct one.

Lol you're fine the airbags won't pop out... I hit a hidden stump at a pretty decent last time I was wheeling threw both me and my friend forward and no air bags came out.

Pm Reaper, he knows. Oh maybe not. Inside joke. But he actually might know now. I think it is 27 on the fuse block, under the hood

just fyi - the sensor is in the same brace that contains your temperature sender (right in the middle of the radiator on a vertical bar). So you'd have to hit pretty hard to contact and to set that sensor off.

Unfortunately, too many people have had the side airbags go off (not the front air bags) when wheeling and not necessarily with anything extreme. I think those are controlled primarily by the rollover sensor and not the front impact sensor, though I may be wrong. I have not heard of any instances of the front airbags going off while offroad. Also know of one H3 owner that had to replace the rollover sensor as it went off, though the airbags didn't go off. Something like two of the three sensors tripped and they are not resettable. Don't recall the exact details, but it wasn't cheap and he wasn't happy.

I don't think its a bad idea to remove the fuse for the side airbags though I've never done it myself.

Just a note! That is not a deployment sensor and hitting it will not deploy the front bags. It is an impact sensor that assists in determining the severity of a frontal collision further supporting air bag deployment by the SDM. Helps the SDM to determine a single or a dual stage deployment of the front bags. The actual determination of a front air bag deployment is made solely by the SDM and is basically determined by a ball, a ramp and some magnets. (Older systems that used the DERM module did use sensors on the front of the vehicle that when crushed, deployed the bags.)

Side air bags are deployed based on either an impact to the B pillar area that crushes a sensor and then the bags deploy, or by a possible rollover. That is usually what sets off the side air bags, the sensor signals a rollover to the SDM and the SDM pops the bags; both sides.

I was driving under 5 mph on a flat dirt road and my roll over bags went off. there is never a for sure answer when a mechanical part malfunctions. better to be safe then sorry. those airbags hit me in the side of the neck, trust me, you don't wanna go through that unless its truly a roll over situation

I thought it was 27 too. I didn't pull it the last time I went wheeling and thankfully, nothing happened. Is anything else on that circuit that would be effected by pulling the fuse?

Your experience is exactly why I wanted to pull the fuse. Not worth the risk for something that takes 30 seconds to do.

I pulled it this weekend and did not experience any negative issues.
