I have a 2014 Wrangler Unlimited and it has Traction Control. I have no idea how well this works i.e. snow, ice, off-road in mud, on a hill, etc. Anybody have any experience with the traction control?
Thanks!
Thanks!
Don't I wish! Unfortunately, I don't have a convenient place to try it - yet - hopefully that will change before long.Best advice is go out and try it.
Interesting, thanks!...Ill admit that it is rather impressive and much better than the ATRAC on my previous FJ Cruiser. Granted the traction control is no exception to say a full locker but it works quite well
A lot of people use the same term for the two systems....and they are actually part of the same system.Are you referring to the traction control, or the brake assist thing that helps if one of your wheels has no traction? ( Brake lock diff or soemthing like that )
The traction control feels pretty standard to me. On the ice it came on quite frequently.
That is without a doubt my #1 absolute hatred of traction control....and that bogging down came close to getting me in an accident several times in my Libby. The traction control would kick in and kill my momentum.they work great in the city not so great in a mud hole where you want to spin to clean the tread.....Also I have found that some times pulling out on a low traction side road on to a main road can be a drag as the vehicle wants to bog instead of accelerate.
id say it depends on the situation your in. keep in mind you can turn the traction control off or partly off for greater wheel spin. take this video for example. this was a couple weeks ago on a goof off kinda sunday. the rover was on street tires and flat out stuck, the geo was on 31" tsl, and my JK not aired down, open diffs, with the factory traction control, and in low range (3.23 gears on 35" tires so everything is low range for me until i regear) you can see that all four tires are pulling on minenot so great in a mud hole where you want to spin to clean the tread
That's a great Jeep commercial.id say it depends on the situation your in. keep in mind you can turn the traction control off or partly off for greater wheel spin. take this video for example. this was a couple weeks ago on a goof off kinda sunday. the rover was on street tires and flat out stuck, the geo was on 31" tsl, and my JK not aired down, open diffs, with the factory traction control, and in low range (3.23 gears on 35" tires so everything is low range for me until i regear) you can see that all four tires are pulling on mine

4lo kills the ESC which is what compensates for over/under steer4lo kills the traction control or at least it does on the rubicons
I believe it's the ESC that's inactive in low range. In all the Jeep videos they show the TC working in low range and it is effective. In another video by ARB, they show the TC to be far more effective than open diffs and they specifically state that they are in low range.TC is not effective off raod. AS mentioned its dead once your in 4LO. If you have Limited Slip, this is not effected. You really only benefit(or not) on the street.
Exactly. But that does limit slip....Its not limited slip. Its meant to control slipping by applying the brakes to the spinning tire.
The TC might need to be disabled for that, but that's not a problem....TC is why in the 2012 (Automatic )and up JK's you can not run a detroit or Yukon Grizzly locker in the rear.
TC is active on the trails as demonstrated in various videos about TC. Watch some of the vids I linked and you will see they are active off road and in low range. It is the ESC that is deactivated in low range....When I was on the trails it wasnt an issue as TC is not active. I switched to the Elocker and my problems went away.
This says TC is off when ESC is off EXCEPT Limited Slip which is NOT TC!! Two different animals.going from the owners manual pdf file
"when in ESC Off mode, ESC and TCS, except for the "limited slip" feature described in the TCS section, are turned off."
It's explained in depth in your manual, which you can download and search off of the Jeep Owners website.
Traction control works on all four wheels, unless you either turn it off (partially or completely . . . read the manual) or put the Jeep into 4Lo. Even in 4Lo or with the traction control off however, the Jeep's "brake lock differential" still operates to simulate an LSD on the front and rear.
If you have a real LSD in the rear that does its job, the brake lock differential will presumably not be triggered very much. Regardless, it won't hurt the LSD.
From the owners manual:
ESC Off
This is the normal operating mode for ESC in 4L range.
Whenever the vehicle is started in 4L range, or the
transfer case (if equipped) is shifted from 4H range or
NEUTRAL to 4L range, the ESC system will be in this
mode. In 4L range, ESC and TCS, except for the “limited
slip” feature described in the TCS section, are turned off
until the vehicle reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h), the normal ESC stability function
returns but TCS remains off. When the vehicle speed
drops below 35 mph (56 km/h), the ESC system shuts off.
The ESC is off at low vehicle speeds in 4L range so that it
will not interfere with off-road driving, but the ESC
function returns to provide the stability feature at speeds
above 40 mph (64 km/h). The “ESC Activation/
Malfunction Indicator Light” will always be illuminated
in 4L range when ESC is off.
----------------------
ESC and TCS are turned off...with the exception of the limited slip function under TCS. That fuction is the off-road programming known as BLD....which differs from the on road programming of normal TCS.
I think you are reading it incorrectly.Here's an excerpt from a paper written by a Jeep control engineer,
"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."
Notice the underlined part, in 4wd low range the BLD functions so there is no need to turn off traction control. If TC is not the same as BLD just by a different name, then how are they different?
