2012 ESC Clarification

Okay, I’ve been searching and reading up on the whole “ESC” that my 2012 JK sport is equipped with. I have a question that I have yet to find a clear answer to so I hope that someone can shed some light on it for me.

First of all, as I understand it (please let me know if I’m off base here)“ESC” is a group of components ie: traction control, ABS, engine braking, etc… all working together to keep the Jeep on the road with traction. ESC stands for “Electronic Stability Control” but this is a group of components right?

Now…..As I understand it, when I’m off road and the Jeep is in 4H the BLD “Brake Lock Differential” is also activated as well as the ESC.

So what I have been doing is pressing the ESC button once. I thought this is what I needed to do to de-activate certain elements of the ESC and get a little more wheel spin when I need it in order to NOT have the Jeeps ESC take over and over ride the BLD.

Now I’ve read that you can press it for 5 seconds for another level of “off” but I’m not sure what that does and why it’s needed.

So my questions are….

1. What is the difference between one press of the ESC button and holding it for 5 seconds?
2. If I do hold it for 5 seconds, how do I return it back to normal operation…hold it for 5 seconds again?
3. What happens to the ESC in 4L if I don't press the button?


Thanks!

1. You can partially disengage it in 4H or 2H.
2. Turn the jeep off and it restores.
3. It is fully off in 4L without you pushing any buttons.

Cool, thanks. I kinda figured it was something like that from what I've been finding out through the search function...so that answers #2 and #3

As for question #1...what is the difference between one push of the ESC button and holding it for 5 seconds, in other words, what's different between partially disengaged and fully disengaged?

This should help.

Electronic Stability Program (ESP)
New MK25/25E anti-lock brake system

Continental Teves’ next-generation antilock braking system, the MK25e, is making its worldwide debut on the 2005 Jeep Grand Cherokee. The MK25e is designed to prevent the wheels from locking during braking, providing increased stability and the capability to continue to steer the vehicle during hard braking. The MK25e also includes traction control (ESP), which detects wheel spin and applies the brake at the spinning wheel, effectively transferring torque to those wheels that have traction.
Electronic Stability Program (ESP) is a stability enhancement system designed to electronically detect and assist drivers in critical driving situations and under adverse conditions...automatically. Using signals from sensors throughout the vehicle, the system determines the appropriate brake and throttle adjustments for directional stability of the vehicle.

Electronic sensors are strategically placed in the vehicle, allowing ESP to analyze steering wheel activity, wheel speeds, acceleration and the vehicles' rotation about its vertical axis (technically named yaw). During motion, the collected data is continually compared to determine whether the actual course of the vehicle corresponds to the direction the driver is steering the vehicle. If not, ESP springs into action, correcting the vehicle's direction to coincide with where the driver is pointing it through a series of brake and engine interventions. The effect is to help correct oversteer and understeer and to coincide with where the driver is pointing the vehicle to help keep it on the road.

Continental Automotive Systems also will supply the 2005 Jeep Grand Cherokee with brake boosters and master cylinders, wheel speed sensors, and the seat heating modules.

During Understeer:

In an understeer situation, the front end of the car tends to slide out. ESP automatically applies the inside, rear brake to help you acheive your desired turn. It may also reduce the engine's power.

During Oversteer:

In an oversteer situation, the rear end of the car tends to slide out or "fishtail". ESP automatically applies the outside, front brake to help you correct "fishtailing".

Advantages of ESP:

ESP constantly compares the driver's intended course with the vehicle's actual course and compensates for any differences.
ESP responds to help you drive safely whenever it senses impending wheel lock-up, wheel spin or loss of vehicle control.
It helps improve traction, maneuverability and stability in all weather conditions.
ESP Assists During All Driving Situations:

Braking

Accelerating

Cornering

ESP functions and components

ESP operation in the WK

ESP (Electronic Stability Program) enhances directional control and reduces driving wheel spin of the vehicle under various driving conditions. ESP corrects for over/understeering of the vehicle by applying brakes to the appropriate wheel. Engine torque is also limited. The "ESP Indicator Light," located in the instrument cluster, starts to flash as soon as the tires lose traction and the ESP system becomes active.

Chrysler introduced an additional enhancement on the all-new Jeep Grand Cherokee, an electronic rollover mitigation system that extends the ESP technology and provides enhanced vehicle stability during emergency maneuvers on all surfaces. The system observes and monitors the vehicle roll attitude and lateral force to estimate the potential for a rollover situation. If necessary, the engine torque is reduced and a short burst of full braking is applied to the appropriate wheel to help stabilize the vehicle attitude and reduce the vehicle's lateral force.

These systems build on the Chrysler Group electronic chassis controls which include Anti-Lock Brake System (ABS) and All-Speed Traction Control (TCS). The Anti-Lock Brake System keeps the vehicle straight while retaining steering capability when braking on slippery surfaces by preventing wheel lock-up. It benefits from state-of the-art electronics that provide a more refined system response than in the past. All-Speed TCS enhances mobility and prevents wheel slip when accelerating on slippery surfaces. It also provides a measure of directional stability control -- an advancement beyond prior traction control systems. Using the wheel-speed sensors, it can detect excessive yaw and help keep the car on the intended course as, for instance, when accelerating around a curve.

In addition to the brake engagement at low speeds used by conventional traction control systems, All-Speed TCS uses throttle control as well. This makes the vehicle less reliant on brake application alone to maintain traction, increases the operating speed range, and more closely modulates speed and acceleration, to provide smoother operation. With All-Speed TCS reducing engine torque when accelerating, it is possible to achieve almost seamless torque application at the wheels. All-Speed TCS also benefits from state-of-the art electronics that provide a much more refined system response than in the past.


Operation:

To turn the ESP system OFF, press the switch, located below the climate controls in the center stack, until the "ESP Indicator Light" in the instrument cluster turns on and the message "ESP SYSTEM DISABLED" appears in the Electronic Vehicle Information Center (EVIC). To turn the system back ON, press the switch a second time until the "ESP Indicator Light" turns off. ESP is always available during braking (in 4WD Hi) even if it has been switched off.

When the ESP system has been switched off, a feature of the system remains active. This feature functions similar to a limited slip differential and controls the wheel spin across an axle. If one wheel on an axle is spinning faster than the other, the system will apply the brake of the spinning wheel and allow more engine torque to be applied to the wheel that is not spinning.

To improve the vehicle's traction when driving with snow chains, or starting off in deep snow, sand or gravel, it may be desirable to switch off the ESP by pressing the ESP switch.

With the ESP switched off, the engine torque reduction and stability features are cancelled. Therefore, the enhanced vehicle stability offered by ESP is unavailable.

If the "ESP Indicator Light" begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions. When the "ESP Indicator Light" is illuminated continuously, the ESP is switched off. To return to the enhanced vehicle stability offered by ESP, press the ESP switch (the "ESP Indicator Light" in the instrument cluster goes out). Avoid spinning one drive wheel. This may cause serious damage to the drive train.

NOTE:


The "ESP Indicator Light" comes on momentarily each time the ignition switch is turned ON.
Each time the ignition is turned ON, the ESP System will be ON even if it was turned off previously.
The ESP Control System will make buzzing or clicking sounds when it is active.


There are two Electronic Vehicle Information Center (EVIC) messages associated with the Electronic Stability Control System:

1. ESP System Disabled

This message will be displayed if the ESP System has been turned off using the switch, or if there is a temporary condition that will result in partial or no ESP function. The "ESP Indicator Light" will be on when the system is disabled or only partial function is allowed. The "ESP SYSTEM DISABLED" message and the "ESP Indicator Light" being illuminated without the switch being depressed is not an indication that service of the electronic brake system is required.

Also, the "ESP SYSTEM DISABLED" message will be present when the vehicle is shifted into 4WD LOW.

2. Service Elec Brake System

This message will be displayed if a condition exists that may require servicing the electronic brake system. When this message is displayed and the "ESP Indicator Light" is on, there is a malfunction of the ESP System. If the "SERVICE ELEC BRAKE SYSTEM" message continues to be displayed after several ignition cycles and the vehicle has been driven several miles at speeds greater than 30 mph (48 km/h), see your authorized dealer for service.


WARNING!
ESP (Electronic Stability Program) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded. The ESP cannot prevent accidents, including those resulting from excessive speed in turns, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others.

I didn't read anything about the difference between partially disengaged and fully disengaged...unless I'm just not seeing it...

What's the advantage of holding the button for 5 seconds?

Pushing the button partially disengages ESP. Holding it for 5 seconds fully disengages it in 2H or 4H. It is fully off automatically in 4L.

The Owner's Manual is confusing at best on the various Electronic Brake Control, or ECS systems!

I THINK that:

Partial ECS off (ECS button push) only disables TCS (traction control system) except for the limited slip-like function of TCS.

Part of TCS stops wheels from spinning, part applies power across the axle when one wheel slips. Partial off allows wheels to spin -mud, snow, etc. - but still sends power to both wheels when needed.

Full ECS off (ECS button 5 second hold, or in 4-Low and under 40 MPH) turns all functions off except ABS, HDC and the limited slip portion of TCS.

HSA and HDC are independently controllable.

Now, feel free to correct this 'cause I'm as confused as anyone...



Edit: Come on daggo, help us out here...!

Ok....got that..... but what is the difference between the two??

What happens when it's only partially disengaged? Obviously there is a difference between the two thus the ability to either fully or partially disengage.

There has to be a difference..."partially disengaged" could mean two things.

1. Only a portion of the ESP system is disengaged 100% of the time.
or
2. 100% of the ESP system is disengaged a portion of the time.

Which one is it?

If it's #1 then which components are still engaged and which are disengaged?

If it's #2 then under what circumstances is it disengaged?

Ok....this is what I was asking about......

So if I don't have HDC (hill decent control?) then if I hold the button for 5 seconds everything is pretty much disabled except for the HSA (Hill Start Assist?) and BLD (Brake Lock Differential)

So what is the limited slip-like function of TCS?

Limited slip portion of TCS = BLD. The Owner's Manual doesn't call it that, but that's the common terminology.

No HDC needed with manual, of course.

I don't know about HSA (Hill Start Assist) with ESC off??? Of course, it can be turned of independently.


Edit: Also, go back and see my slightly edited post above...

Ok...I see....I think, LOL!

So BLD is the limited slip portion of the TCS which is also just a portion of the ESC system...

So if I'm understanding this correctly when I press the ESC button one time, It partially disengages the system allowing the wheels to spin without the jeep trying to stop them. The BLD will try to get them to both spin at the same rate but it won't try to stop the wheels from spinning as it would if the ESC was activated. This should allow me to get the wheels spinning while in mud, snow, sand, etc...where wheel spin may be desired.

Shouldn't that be all you need when off roading? What's the benefit of holding it for 5 seconds?

You are correct, however I saw nothing in the 2012 owners manual about holding the button for 5 seconds. In 2WD or 4HI, push the button once and the system is partially off. Allows more wheel spin for mud, snow, etc. Shift into 4LO and the ESC automatically turns completely off.

Right. The OM says nothing about holding the button for full off. But, many posters have recommend it as working. I've done it, but, honestly don't know if it really made a difference.

The OM does say that:

in 2H - 2 modes of ECS are available - I assume they are: 1. All On, 2. Part Off ?

in 4H - 3 modes of ECS are available - Must be 1. All On, 2. Part On, 3. Full Off.

in 4L - 1 mode of ECS is available- Full Off.

So if indeed you can turn it "fully off" by holding the ESC button for 5 seconds.......what does that do and how is it better/different that just pushing the button once?

So far all I've been doing is pressing the button once and I've been very happy with the way the Jeep handles itself off road but I've been reading about the "full off" option and wondered what it exactly does?

In my Patriots, which have the same basic system as my Wrangler, the first (1/2 off) option disables the engine control portion of the ESC system, leaving the brake-based directional control portions enabled. Full off disables everything BUT the BLD's. The only way to disable the BLD's is to pull the fuse for the ABS system.
(The Rubicon just locks the axle, eliminating the NEED for a BLD. It's still on, just not used.)

You need to look at a couple different sections of the manual and kind of connect the dots. Unfortunately the electronic version of the 2012 manual does not seem to have an index like the 2009 version, making it much more difficult.

First thing to clarify is that many, many people on the forums confuse partially off, fully off, and permanently off. Partial and full off are temporary. That means next time you cycle your engine they will be on. You have to perform the wheel dance for permanent off.

The ESC or Electronic Brake Control System consists of: Anti-lock brake, brake assist system, electronic roll mitigation, electronic stability program, and traction control system. Unmentioned in there (because it is mentioned later) is the limited slip braking feature, also known as BLD.

Pushing the button once for partial off, turns off TCS only. Holding it for 5 seconds turns off everything but BLD.

Now the real question, WTF does that mean? I don't really know. When I go off road and am going to encounter sand (most often for me) or mud, I choose fully off in 4H. My thinking is that if it's good to have it off in 4L, than it's good to have it off in 4H. Because your speed is limited in 4L, Jeep figures there's no need for ERM or ABS. I figure that off road in 4H, I don't need those things either. However if you were on the road in 4H in snow conditions, you might still want those systems functioning.

Daggo....

Thanks!

I've got it figured out now....I don't need to know exactly how all the systems works together, I'm pretty up to speed with each ones basic operations and why they do what they do.... What I wasn't sure about was what is on and what is disabled and when it's on and when it's disabled when the button is pressed (either once or five seconds) and you've helped with that.

As stated I've been happy with how the Jeep performs off road and for now my main issue is being able to spin the wheels freely when I want them to. So far one press of the ESC button has done the trick. The next time out wheeling I will try fully off and see if I can tell the difference.

You're right about the 2012 manual it's pretty vague about how these systems work together as well as when and how to turn them off. But, that's what forums like this are for and folks like all those who took the time to post.

Thanks guys!

Thanks Daggo!

I went back and looked at the 2009 OM, and it explains this MUCH better than my 2012 OM does!

Here's the whole enchilada from that manual... No wonder Daggo knows this stuff so well:

Quote:



2009 Wrangler Owner’s Manual:

Beginning on page 323

Electronic Stability Program (ESP)


The ESP system has three available operating modes in
4H range. The system has one operating mode in 4L
range. Two-wheel drive vehicles and four-wheel drive
vehicles in 2H range have two operating modes.

4H Range (4WD Models) or 2WD Models
On
This is the normal operating mode for ESP in 4H and
2WD vehicles. Whenever the vehicle is started or the
transfer case (if equipped) is shifted from 4L range or
NEUTRAL back to 4H range, the ESP system will be in
this mode. This mode should be used for most all driving
situations. The ESP should only be turned to “Partial Off”
or “Full Off” for specific reasons as noted below.

Partial Off
This mode is entered by momentarily pressing the ESP
OFF switch. When in _Partial Off_ mode, the TCS portion
of ESP has been disabled and the “ESP/TCS Indicator
Light” will be illuminated. All other stability features of
ESP function normally. This mode is intended to be used
if the vehicle is in deep snow, sand, or gravel conditions
and more wheel spin than ESP would normally allow is
required to gain traction. To turn ESP on again, momentarily
press the ESP OFF switch. This will restore the
normal “ESP On” mode of operation.

ESP OFF Switch
NOTE: To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily pressing the
ESP OFF switch. This may be done while the vehicle is in
motion.

ESP Off (4H Range Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneuverability
due to trail conditions. This mode is entered by
pressing and holding the ESP OFF switch for five seconds
when the vehicle is stopped and the engine is running. In
this mode, all ESP and TCS stability features are turned
off except for the “limited slip” feature described in the
TCS section. After five seconds, a chime will sound, the
“ESP/TCS Indicator Light” will illuminate, and the “ESP
OFF_ message will appear in the odometer. Refer to
“Compass and Mini-Trip Computer — If Equipped” in
Section 4 of this manual. To turn ESP on again, momentarily
press the ESP OFF switch. This will restore the
normal “ESP On” mode of operation.

NOTE:
• The ESP system will change to “Partial Off” mode if
the vehicle speed exceeds 40 mph (64 km/h). After the
vehicle speed is reduced below 35 mph (56 km/h), the
ESP system will return to “Full Off” mode.
• The “ESP OFF” message will display and the audible
chime will sound when the shift lever is placed in the
PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.

….

ESP Off
This is the normal operating mode for ESP 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 ESP system will be in this
mode. In 4L range, ESP 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 (48 km/h). At
40 mph (48 km/h), the normal ESP stability function
returns but TCS remains off. When the vehicle speed
drops below 35 mph (40 km/h), the ESP system shuts off.
The ESP is off at low vehicle speeds in 4L range so that it
will not interfere with off-road driving, but the ESP
function returns to provide the stability feature at speeds
above 40 mph (48 km/h). The “ESP/TCS Indicator
Light” will always be illuminated in 4L range when ESP
is off.
NOTE: The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
….

Disabling ESP for Modified Vehicles (4WD Models
Only)
Vehicles modified with larger tires and/or suspension
lifts may experience early ESP activations as compared to
a non-modified production vehicle depending on lift
size, tire size, suspension changes and/or driving habits.
If early ESP activations are experienced while driving a
modified vehicle, the additional ability to permanently
turn off ESP is available. A steering wheel/ESP button
maneuver must be performed to permanently disable
ESP and defeat the functionality of the ESP switch.
Repeating the procedure will return the system to normal
ESP operation and restore ESP switch functionality allowing
ESP “Partial” or “Off” modes.

The following procedure will disable (or re-enable) ESP
functionality in the vehicle:
1. Shift the transfer case into the 4H range position.
2. Turn the steering wheel until it is centered and the
wheels are pointed straight ahead.
3. Cycle the ignition key OFF to ON.
4. Wait approximately five seconds for the system bulb
check.
5. Turn and hold the steering wheel one-half turn to the
right (clockwise).
6. Press and hold the ESP OFF button for seven seconds.
7. Turn the steering wheel back to center, and turn and
hold an additional one-half turn to the left (counterclockwise).
8. Press and hold the ESP OFF button for seven seconds.
9. Turn the steering wheel back to center.
10. Press and hold the ESP OFF button for seven seconds.
11. Cycle the ignition key to OFF.
After performing the ESP disable procedure correctly,
“ESP OFF” will be displayed in the odometer for approximately
12 seconds each time the ignition is moved to ON.
Repeating the ESP disable procedure will re-enable normal
ESP operation.

If you go back to page 316, it gives a complete breakdown of each component and what it does. This includes a very lengthy explanation of HSA.

Man, I'm going to refer to the 2009 OM first, from now on. WTF Jeep? They just made it incomprehensible in the 2012 OM!

Thanks Bill!!

Wow, my manual doesn't have anything like that! Plus, my DVD disc won't play on my lap top (for some reason) so I have to use my house computer to read it and it sucks not being able to be in the Jeep at the same time as reading the manual. I'll probably end up calling my dealer for a printed manual.......I should ask for a 2009 manual he..he..he..

Thanks again guys...gonna copy, paste and print that Bill!
