3 short horn honks?
 

Just got my car back from SpecialtyZ after having some mods done...Stillen G3, GTM oil cooler, F.I. cbe, H&R 20mm wheel spacers all around, spc rear camber kit, Swift Spec-R springs and, RevUp tune.

When I went to pick her up, Seb pointed out that now, when you press the start button (w/o the clutch in), the car's horn sounds 3 short honks.
She starts & runs fine though.

I just got home and discovered that this same thing happens by simply pushing the clutch in with the car totally off. When the clutch is almost all the way depressed, the horn makes 3 short, quick honks...wtf is going on here?:confused:

I'm hoping someone here has had this experience and can tell me what's going on.

leaning on horn while pushing button? lol

That's a first... Video?

Ummmmmmmm... LMAO... Never seen that before, jeezus

Seb is looking into it too, I'm sure it's no big deal, just annoying.

I'd take the tune off first. And do you have an aftermarket alarm?

No aftermarket alarm.

As for the tune, I'm sure Seb will fix whatever the problem is.

He & his shop have a stellar rep.

:iagree:

I thought of the tune first, but the alarm question is a great one.

No doubt about that, just giving my problem solving input

Not normal!

Remove horn. Problem solved.:ugh2:

Odd for sure.

I would Flash the car back with the Stock ROM an see what happens. See if the issue goes away then.

Either something screwy in BCM or maybe related to a launch control setting that is accidentally activated?

Wild guess: The theft alarm system is enabled. Try turning it off.
