I have a quick question.. I tried turning my traction control while in 2wd.. i feel like all it does is light up on the dash board and the traction control is still on. Is it just me or is the light just there to make people happy? I know 4wd n 4low it goes off.

Thanks, Ryan

 

In 2wd when you hit the button it only turns traction control off partialy you can not completly disable it in 2wd. Only complety off in 4 hi and auot in 4low

 

You can increase the amount of its disconnectedness by holding the button for 5-10 seconds. There is a complete turn off procedure detailed in the owners manual but it only works for 4-Hi.

 

In order to perform the disable procedure, the t-case must be in 4hi, but I believe it will be disabled in 2hi, 4hi, and 4lo.

Have you seen anything that would indicate it won't be disabled in 2hi?

 

Okay Thanks, I just didnt want to think i was crazy thinking it didn't go off all the way.. What happend to the jeeps with out traction control... :(

 

Steering wheel dance disables it completely...100% off in 2 and 4WD. I can drift my to my hearts content in my JK now. I can spin my tires in mud and snow now. I really love driving my Jeep even more now!

 

Why would someone want to disable traction control?

 

Curious about that too? When and why would you disable it? I know offroad but not sure why?

 

If you are stuck in snow the traction control can work against you. It can lock up wheels when you need some spin. This is not to be confused with the brake lock differential. On a wrangler without lockers, it proves to be very useful.

 

from a Chrysler engineer:

There are several parts to traction control and they are enabled or disabled depending on the driving mode the driver has chosen. When the vehicle is in 4wd high range and the Electronic Stability Control System (ESC) is on, traction control uses the brakes and engine torque control to limit how fast the driven wheels can spin relative to the actual speed of the vehicle.

This helps provide maximum traction along with stability. In addition to controlling how fast the driven wheels are spinning, there is a feature of brake traction control that controls wheel speed side to side across a driven axle and is called BLD, or "brake lock differential."

BLD does not care how fast the wheels are turning, just that they are turning at the same speed. It provides improved traction capability similar to a locking differential.

There are times when controlling how fast the wheels spin may not be desirable for driving conditions such as mud or deep snow. In this case, pushing the ESC button once (in 4wd high range) will disable the brake and engine portions of traction control that control how fast the wheels are allowed to spin but leaves BLD on. In 4wd low range, only BLD functions so there is no need to turn off traction control.


Just to get this out of the way; from the Jeep perspective, BLD is not a substitute for locking differentials. It is a means to greatly expand the off road capability of vehicles that were not purchased with or do not offer locking differentials.

A Jeep vehicle with BLD will negotiate almost any obstacle or driving situation that a similar vehicle with locking differential will. BLD does require a change in driving style and more torque to negotiate the obstacle.
