Is it worth the trouble to remove this system?

Easy enough to do. To turn off the dash light, ground pin 6 of the fire supression module 16 pin connector, LG-RD wire. (Pin 7 of the same connector, BK-LB is a ground).
[edit: thats for 2006+ canbus cars]

The system uses gas generators like airbags do, and should be treated the same way. Disconnect battery and wait 20-30 minutes for backup capacitors to discharge before working on the system.

I have the factory manuals, and they show in detail R&R procedure.

The reasons I'm debating removing the system...

1) planning on lowering the car. There is a large assembly that hangs under the trunk floor that looks very vulnerable.

2) Most CVPI fires were caused by high speed rear end collisions. Most of these were a CVPI hit when stopped behind a ticketed or broken down car on the side of the road. I doubt I'll ever be in this situation.

3) already have the Kevlar trunk pack, and I load out the trunk per Ford's recommendations.

4) Plan on new shocks, sway bar and rear end gear swap or whole rear end swap. The FSS is really in the way if you do any work in that area.

5) large control box under rear seat. I'd like to use that space for power amps, etc.

6) Weight/ complexity. The FSS in total looks like it weighs about 80 lbs. Also, why keep an unneeded, potentially dangerous and fussy system?

BTW, of course I'm going to keep the overhead console activation button. Who can resist a big red button? Just have to figure out something cool to wire it to.

I think those are all pretty solid reasons. Maybe wait until you're actually going to do the rear end work to remove the system, since you'll be in there anyway?

Couple things:
1) I might be wrong, but I don't think any part of the fire suppression system hangs under the trunk. You might be looking at your EVAP canister.
6) Emergency party lights. Possibly with hardwired dance music.

Don’t expect the trunk pack kevlar to stop any penetration, it’s extremely thin and in my opinion useless. I took my trunk pack out to put the spare where it wouldn’t get pushed into my kids in a rear collision. Naturally I had to test the kevlar, only thing it stopped was a quarter of the pellets from no7 field load from about 20yds. It was easy to punch a cheap chinese steel knife through, a kershaw or benchmade would go through like butter.

It's not made to stop bullets or knives, it's to give an extra layer to try to prevent bigger solid things that are sitting parallel to it from being pushed thru it.

HI!
Reviving this old thread.

The light on my dash comes on - and i wonder if i should just have the system removed. The light itself doesnt really bother me.
I don't have the factory manuals.
Would it be risky to have a regular mechanic remove the system?
If you take out the fuse and disconnect the battery, are there any risks in 'just' removing the system?
Will the missing system create an error code so that the car wouldn't pass inspection?
