'ETS OFF' Light

My traction system used to work. Then one day i was driving and it turned itself off. The ETS off light is illuminated, no other lights are lit. When i hit the button on my shifter to turn my ETS on and off, the light just stays on saying that the tractions system is off... how do i get this light to turn off and get the traction system running again? what could be the problem?

    brake fluid if ull all fuses look fine under hood and on side door panel. no abs codes in sight. checked with scanner. abs and brake lights are not on. just the ETS OFF light and the traction system wont engage. switch is not bad, because if the engine is not started but the key is turned to 1st setting if you push the button the ETS OFF light goes on and off, but as soon as you start the engine its automaticly off and wont turn back on.

The first thing that comes to mind is a wheel bearing/wheel speed sensor in the a.b.s. brake system. usually the abs and/or brake lite will come on also. maybe check fuses in cab and under hood just to be sure. make sure brake fluid is full. a diagnostic scanner that could access a.b.s. codes may be necessary to pinpooint problem.

Why is track off light on?


The amber TRAC OFF indicator will illuminate in order to alert the driver of an existing malfunction with the Enhanced Traction System (ETS). In this situation, enhanced traction will not be available. The ABS VI/ETS must be serviced in order to regain enhanced traction ability.

Probably a DTC-diagnostic trouble code stored in the EBCM - electronic brake control module !

What is this light ETS what that mean


Enhanced Traction Control use the ABS system to improve your vehicles traction by slowing an individual wheel down (slipping wheel will spin) thus applying the one that has traction.

What is the "Trac off"


It means you turned off the traction or pushed the ETS button on the gear shift.

The Enhanced Traction System is an all-speed engine based traction control system used by General Motors Corporation in many of their models. In some models, the driver has the option to disable this system by pushing a button marked "ETS". The system uses sensors to monitor wheelspin and reduces engine speed, upshifts or retards ignition timing to improve traction

What does the ETS off light on the dash mean


Hello there
let me try to explain it the best way i can

If you are talking about the light coming on when you are driving in slippery conditions, this is normal. If you are talking about it staying on all the time, the ets is either turned off or you have another problem. Let?s take a moment and explain why the electronic traction control which is called Enhanced Traction System (ETS) warning light will turn on when the engine computer sees a problem. The ETS system monitors wheel speed via the Anti-lock Brake System (ABS). If the ETS system sees a wheel spinning due to snow, ice, rain etc., the ETS computer sends a request to the vehicle?s engine computer to reduce torque. The engine computer responds with a combination of strategies. In the engine computer?s bag of tricks to stop wheel spin it can perform any one or combination of the following; cut fuel off by trimming or turning off fuel injectors, ****** the spark timing or up shift the transmission. In the days of old we just let up on the gas pedal. Now the computer does it for you. If you have an engine running problem it is more of a problem than you realize. The engine computer is the high command center. The engine computer will work and respond to information from the other computers in the vehicle. But in the event there is a system or running problem that the engine computer is responsible for, ?it will? lock out all of the other vehicle computers. If there is an engine running problem that causes the engine computer to store a code and turn on the ?Check Engine? light guess what computer doesn't talk to the others? The engine computer. The ETS computer gets all put out when this occurs and turns its warning light on in protest. So, there you have it. If the check engine light is on the ETS warning light will come on as well and the ETS system will not operate until the engine computer problem is corrected.

ETS LIGHT CAME ON AND CHECK ENGINE LIGHT 1997 chevy cavalier 2.4


ETS is Enhanced Traction System is used to stop wheel slip thru reducing engine output. And if the light is on it doesn't mean you will spend x amount of dollars to fix it! It just means that ETS has been disabled because you have a engine problem and the computer cannot reduce power to the wheels because the engine might stall so the computer disables the system! Now some cars come with a switch by the shifter that turns on and off the system because if you get stuck in the snow traction control will keep you from getting stuck

What does it mean when the ETS light and the check engine light are on?


Check engine light is for telling you that there is A problem with the fuel injection or emissions system, Most of the time there is no major problem to really wory about. ETS is the light for the Enhanced Traction system (traction control) This is not A vital component of your car.

If these two lights come on together then the extra traction sensor is broken and needs to be replaced when the sensor is fixed the check engine light will go off and the ets light will work properly again.

What does ETS mean and how to use it


Hello! ETS stands for Enhanced Traction System. It is a system that limits traction loss by utilizing the anti-lock braking system (ABS) to keep the tires from spinning on slippery or loose pavement. If you press the button, and the ETS light is illuminated on your instrument panel, that indicates that the system is disengaged. To engage the system, push the ETC button on the shift handle, and the light should go off. If it doesn't, that could be an indication that you have an ABS malfunction and you should have that diagnosed.

I hope this helps and thanks for using FixYa!

Whatis the ETS light stand for


Hi,

ETS - Enhanced Traction Control.

Enhanced traction control used the ABS system improve your vehicles traction by slowing an individual wheel down ( slipping wheel will spin ) thus applying more power to the one with better grip and the speed sensors monitor all four wheels to make sure that one is not spinning much faster than the rest.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
