Can someone explain the electronic traction control and ESC to me?

The manual and factory descriptions of these control systems don't really explain what these systems are DOING when they engage, and that's what I'm trying to understand.

So when the traction control light comes on, what is the Jeep doing? If the wheel with the power loses traction, does it just apply the brake thus transferring the power to the other one (giving it a "poor man's locker" effect)?

What about the stability control system? All it says is that under heavy axle articulation in 4LO it "applies the brakes more aggressively"? Why would I want it to do this?

ok et me try and help you out, and this is to my understanding i have a Race license as well as three high performance driving schools... if im wrong some one shoot me.


ESC (control) or ESP (program) however you want to put it, detects the loss of control, aka loss of steering. when detected it uses independent braking control to help steer and regain control of the car. In some systems it also will reduce the power from the engine using a downshift style to help slow the car till control is once again regained by the driver. such as breaking inner wheel to stop understeering and outer to stop over steering. It can also help prevent rollover to a small extent by releasing the break power on the downside wheels.

Hope some of this helps you out, but for FYI use it on roads, High speed off road, but turn that thing off for any real wheeling

The explanation above is great. He just forgot to mention that it is CRAP.

not that it is crap per say, just that it has limitations to those who can actually drive a car. for your 17 year old or grandma it is amazing. As long as i can turn it off im a happy camper, now ABS is the thing that gets me all worked up... thats the first fuse to get pulled!
