Stabilitrak ошибка cadillac escalade

Авто: Эск 2007, 73К пробег.

Ехал по трассе — все норм, свернул на проселочную… вдруг запикало по-очередно: «Service Stabilitrak», через пару секунд — «Service Traction Control» и в добавок «Reduced Engine Power» …… при этом авто перестало практически ехать….. типа мозги ограничили мощность. «Чек» естесственно горел. Кое как доковыляв до места назначения, оставил авто. Через час завел и поехал — все норм. Пиктограмм нет, но чек так и горит. Проехал где-то 40км в обычном режиме, где-то 100км/ч, где-то 160….. Выехал на трассу, стал разгонятся и нааааа те, опять та же хрень. Машина едет очень хреново, коробка вообще не желает переключать. Скорость — 80км.ч по правой полосе. Причем когда едешь в горку, то скорость падает ….. начинаешь давить на газ, двигатель начинет дергать и в какой-то момент перебрасывает на 2 скорости вниз и ты на 4тыс оборотах секунд за 10 увеличиваешь свою скорость на 10км/ч….. прикольное чувство, как будто в Эск поставили двигатель от мопеда …… Потом я догадался воспользоваться мануальным режимом коробки, что несколько улучшило ситуацию — теперь я мог уже ехать со скоростью 110км/ч… правда до такой скорости ее приходилось разгонять несколько минут

Остановился заправке — заправил полный бак. Завелся — опять все ок. Правда через 2-3км пути опять таже хрень ……. Так я и перся в таком режиме из Тулы в Москву — задолбался в общем В добавок: подъехав к дому я даже на бордюр вскарабкаться не смог по началу — мощности не хватило … но с разбега залез. + к этому при переключении с D на R и обратно слышен лязг затвора…. видимо хана крестовинам , т.к. переключения во время этой поездки порой были очень жесткими ((

Может у кого было такое?

Клему специально не скидывал, что ошибки остались. Комп еще не подключали — только в четверг поеду в сервис.

Просто хочется узнать, было ли у кого подобное и что оказалось в итоге?

Полазив по буржуйским сайтам, я выяснил, что этот «набор» из трех пиктограмм очень популярен на траках ГМ, причем от пробега и года выпуска не зависит.

Происходит эта фигня и от оторвавшегося проводка заземления, и от засранного дросселя…… там еще штук 8 причин, и вроде как считывание ошибок даже не поможет.

А как проблема решилась у вас?

ЗЫ. Дроссель 5-7К назад чистили.

One of the most common issues with the Cadillac Escalade, or any newer GM vehicle, is the “Service StabiliTrak” warning.  

StabiliTrak is GM’s electronic stability control system. It does much more than a standard traction control system. It is one of the most innovative and vital safety features on your Cadillac Escalade and can keep you from crashing when skidding.

If you have a service StabiliTrak message, your vehicle will no longer be assisted when a loss in lateral traction is detected. 

The number one reason that the StabiliTrak system fails is a wheel speed sensor issue.

How The Stabilitrak System Works

Stabilitrak uses a complex system of sensors to detect whether or not your Cadillac Escalade is appropriately responding to your input in emergencies.

StabiliTrak: Main Components

• Wheel speed sensors– They measure how fast each particular wheel is turning.  There’s one on each hub.
• Rotation rate sensor– Measures lateral speed and rotation around the vehicle’s centerline.
• Steering wheel position sensor– Measures how many degrees the steering wheel has been turned.
• Control Unit– Takes the data from the three sensors listed above and determines when to activate the StabiliTrak system. It can also tell the powertrain control module to cut engine power if needed.
• Hydraulic System– Can activate one brake at a time.  Usually, it piggybacks off of the ABS.

How It Uses These Components

The StabiliTrak control unit uses data from its sensors to apply a specific brake or reduce the engine power to correct the slide and get your Escalade pointed back in the right direction.

For example, if your Escalade is sliding on ice, StabiliTrak can apply one of the rear brakes to help get you pointed in the right direction. Here’s a video from GM that shows precisely how the system works.

Loss of StabiliTrak assistance is not going to be noticed during everyday driving.  It only activates when it detects that your Escalade is not moving in the direction you steered or if it detects that a skid has been overcorrected.  Most of the time, you’ll feel it when it engages.  

• Service StabiliTrak Warning: Your Escalade’s “Service StabiliTrak” warning light is the number one indication that something is wrong.
• Cruise Control:  If one of the wheel speed sensors is not working correctly, your Escalade may lose cruise control.
• Traction Control Not Working:  Your Escalade’s traction control system primarily uses the same sensors to determine if a wheel has broken traction.  Unlike StabiliTrak, which controls lateral issues (sliding), traction control keeps the wheels from unnecessary spinning. You may get a “service traction control” message and the “Service StabiliTrak” warning simultaneously.

Cadillac Escalade:  Service StabiliTrak Light Causes

Many things can cause the StabiliTrak system to lose its ability to function, but the most common one is a wheel speed sensor. A good scanner should tell you which system has failed and is worth its weight in gold if you’re trying to fix your Escalade’s StabiliTrak system.

Wheel Speed Sensor

Wheel speed sensors are the number one reason that the StabiliTrak system fails.

If one of the wheel speed sensors is having issues, your Escalade will no longer be able to tell if all wheels are turning at the same speed.  Without this data, the “Service StabiliTrak” warning will turn on. 

Wheel speed sensors are exposed to road debris, mud, and salt.  This can cause them to fail or their wiring harness to short out.

One telltale sign that the wiring harness to one of the front wheels is failing is the Service Stabilitrak warning when turning your Escalade to the left or right. This is because the harness moves a little while you turn, which can cause the wheel speed sensor to connect and disconnect intermittently.

Brake Pedal Switch

Your Escalade’s brake pedal switch does more than just control whether or not your brake lights are turned on.  The ECU and StabiliTrak control units use this switch to know when you’re hitting the brakes.  If the switch isn’t functioning correctly, these systems may be disabled.

Faulty Stability Control Module

The Stability Control Module is your Escalade’s computer that controls the StabiliTrak system. It may have failed or needs to be reset.

Wrong Tire Size

StabiliTrak may not work correctly if the tire size is not what GM calls for your model Escalade.

Many other less likely issues can cause the StabiliTrak system to stop working as well.  It’s a good idea to test and see if you have any trouble codes.  They may provide you with clues that’ll help you fix it.

Common Questions

How to Reset the StabiliTrak System

GM recommends that you power down the vehicle for 15 seconds to give the StabiliTrak system time to reboot.  If it works after firing your Escalade back up, great!  If not, it may be time to have it serviced.

Service Stabilitrak and Check Engine Light

While the StabiliTrak system won’t cause any engine problems when it has issues, you may get the service engine soon light with the “Service StabiliTrak” warning. There could very well be codes stored that can tell you what part of the traction control system has failed.

This is good news. The stored codes should give you a solid place to start fixing “Service StabiliTrak” in your Cadillac Escalade. You’ll need a good code reader that can read codes stored in the body control module.

Service Stabilitrak and the ABS Light

The ABS and StabiliTrak systems use the same wheel speed sensors. Fixing one will more often than not clear the other when you have the service Stabilitrak and ABS light on simultaneously.

Conclusion

Although it may be tempting to ignore the Service StabiliTrak warning, it can be dangerous not having the system available when needed.

While driving your Cadillac Escalade without traction control or StabiliTrak won’t cause a breakdown, you are operating your vehicle without an important safety feature.
