ETS LIGHT AND ABS LIGHT ON - 1998 Pontiac Sunfire

you need to retrieve ABS code to solve the problem

The most probable cause for the ETS (Electronic Traction Control System) light is the ABS light. When there is a problem in the ABS, ETS is disabled.

The ETS uses ABS data to help control the ETS system. You will need to have the ABS computer scanned for codes.

This light usually comes on if you have a failed wheel speed sensor but these vehicles are common for the ABS module to fail causing the same problem. You can back probe the wires comming out of each wheel speed sensor with the wheel lifted in the air and check for ac voltage as you spin the wheel.

What ever sensor does not put out voltage needs to be replaced if they all seeem to work it is likely the ABS module. But before you replace any parts you would want to have the ABS module checked for codes at one of your local shops that has a high end scan tool that can access those codes.

Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

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.

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!

Chevrolet customer service said the ets light means enhanced traction control (ets) check the fuses. if you do not find a fuse blown you need to take it to the nearest chevy dealer so they can run a diognostic on it to find the code and replace any electrical parts that need replaced so this light will shut off.

ets light is fro throttle unit fault you have dirty throttle plates or bad throttle unit /

Have your brake pads and rotors checked if you have worn pads this will activate the ABS Antilock Braking System light. The ETS Electronic Traction System uses this ABS to prevent skidding if the tires should lose traction.

the wheel speed sensors may need adjustment on the rear

You would need to get the codes read from the computer as these may all be related. A check engine light can cause an ETS, which inturn can cause an ABS, or vice-versa.
