I have been looking at used 2007 Suburbans and Yukon XLs but when I look at the RPO code sticker in the glove box I have yet to see JL4 (Stabilitrak or Active Brake Control) listed on any of them! Am I just unlucky and none of the ones I have looked at have it or since it supposedly became Standard Equipment in 2007 it was removed from the RPO list? Do they only have traction control since it does have the button for this? As a side note, some of the 2006 and older Suburbans and Yukon XLs that I have looked at actually have the JL4 code listed. Please help.

Update, the strange thing is, if I hold the Traction Control Off button down for 5 seconds, it actually does say "Stabilitrak off" on the display! So it does have it?

I have an 07 Tahoe and and my RPO codes do show the JL4 listed...

that's the fun button that lets you spin doughnuts in the snow

in2pro

Haha! GM should label that button "Fun / No fun"

I saw on other forums that says you perhaps cannot have Stabilitrak on a 2WD vehicle? Another said you cannot have it if you have the G80 locker which mine does. Hmm. Once I buy it, I will take it to the dealer to have checked out.

No, that can't be true either as my Tahoe is 2wd and has the G80 locker, here is my RPO codes for my 07 Tahoe
But if you have the button and the light comes on the IP then obviously you have some form of traction control, maybe you just don't have the specifics of the JL4, you might want to decipher all of the RPO codes to see if you applies... I see that you do have a different gear ration (GT4) which is the 3.73, mine is the (GU6) which is 3.42

At least GM gives you a button... in my 2012 Wrangler I had to cut the ground wire to the center yaw sensor and wire in a momentary off switch.
Cutting ground to the sensor killed the T/C and stability control... which made it possible to do doughnuts.

hmmmm...... doughnuts..... (Homer Simpson)

Restarting the vehicle reset the system.

That is strange that mine does not have JL4 then, makes no sense. I decoded the others, only JD9 for the brakes mentions "W/Vehicle Stability Enhancement System" which might be something.
