Hey guys, I have a unique problem. When I go above 75 mph, i hear a beeping sound. As soon as I drop below 75, it stops. Anyone else experiencing this ?

 

Are you driving a coupe? I understand that it will beep and warn you if the rear wing doesn’t go up around that speed.
I’m very new to this car, I’m sure others will have more probable causes.

 

Coupe or Roadster, the function is the same: The "wing alarm" goes off at around 91mph. I've not heard of it at 75mph.

So, is the wing going up at about 62 and down around 35? Let's start there.

 

Wing works like clock work. Up at 62 and Down at 35

 

Try this:

Turn headlights on.
Pop hood.
Yank battery ground cable off battery post.
Wait at least 15 seconds.
Put battery ground cable back on.
Turn off headlights.
Start car and drive test it.

If that does it, be very suspicious of your battery, battery terminal connections, ground cable connection to chassis and the block to chassis connection.
If the battery is 48 months old or older, replace it.
THEN, do one of these mods:

If the above does not change anything - post here again. NOT that I have any more suggestions, but maybe Dave or George or Greg or someone does.

Roger that!!!

 

One other thing. IF this is a Roadster:

Does it beep with top down?
Does it beep with top up?

If the answer is NOT yes to both, that is a clue right there. One "no" and one "yes" indicates that you have a top problem, and the in one case, the system is fine, but in the other case, the cycle apparently did not complete.

 

Does your cruise control work at normal speeds and at that speed?

 

I may have the answer to this. Last week I was running through all the Starscan menu options on my latest Crossfire purchase, and as I recall, I saw listed a 75 mph alarm option. I thought it was strange to have that. I believe it was under the dealer set up options. Hopefully, I can find the time tomorrow after work to confirm this and post a follow up on it.

 

Thanks Toolman!

 

As a matter of fact, my cruise control is spotty. Works sometime

 

Pizzaguy, thanks for the suggestions. I tried it but it did not erase the beeping.

 

Over ten years on this forum and I've not heard of this before.

Now where do we send him to get it turned off?

 

I remember this popping up before. See post #7 for more details.

Good stuff, 180! I have scheduled an appointment with the dealer tomorrow. Let you know the outcome

 

Obviously, any concern about senior-citizen memory issues is wasted on YOU.




(On a related note: I think the reason I don't remember that post is, well, that post was made during a RARE time I had a girlfriend.)

 

The outcome will be that they try to turn the beep off, they goof the ECM and you are out $2200 for an ECM.

You DID say "Dealer", didn't you?

 

 

Hi Toolman, is this from the dealer or something else?

 

It is from my Chrysler Dealer Starscan Scanner hooked up to one of my Crossfires.

The problem is most Chrysler dealers no longer have the original scanners used on the Crossfires. Their current tool is online Witech with the Micropod 2. They will have to request the special "Enhanced" DRB III emulator for it to work on the Crossfire if they no longer have the old scanner. The Enhanced emulator only works with the prior version wired Micropod 2.

The DRB III was for 2004 to 2006 Crossfires, and the Starscan for 2007 and 2008. Both tools require special cables to work with Crossfires. The standard cables that come with them will not work..
