I have done a bit of research and have yet to find anything helpful. I recently bought a 2010 Ranger; it has been a fleet vehicle since it was brand new. The truck has some sort of warning beeper that goes off (installed by the fleet) every time the truck approaches 70 mph. Any idea how I can remove/disable this thing? Any help would be greatly appreciated.

 

Your Ranger may have Ford's "MyKey" feature. Did you get more than one key with the truck?

 

No extra key. I am fairly certain this was an aftermarket addition by the fleet owner to ensure that drivers didn't speed. It works too-this thing is seriously annoying.

 

If it's an add-on, then I suppose you'll need to figure out where the "module" (or whatever it is that beeps) is located, and then cut off power to it. (I know, easier said than done.)

Where do you hear the warning beeps coming from?

 

If you know where the truck came from, contact their fleet manager, see if s/he is willing to offer info.

If that won't work out. Try to put it on a local dyno, so you can crawl around the dash and look/listen. Have your dash torn apart first to save time.

If that doesn't work out. Hire a couple Hobbits, one to drive and one to listen.

Seriously doubt a 2010 Ranger has MyKey.

Says it may be a feature embedded in the GEM, or SJB depending on vintage.
