I had the exact same problem with my 2004 Cavlier. I took it in and the dealer said it was a voltage problem with my speed regulator located in one of my wheel bases. I had it replaced under my extended warenty. I suguesst taking you car to a mechnanic as soon as possible, cause it could be that sensor, or an electrical issue all together. Especially if it is that sensor, since it effects your braking system, traction system, and the overall drivability of the car.

This soundslike a bad speed sensor, you will need to have the computer scanned for codes, the computer turns on the light and stores the code, the code will tell you what has gone wrong and with some testing you can find the problem, the most common problem could be a bad wheel speed sensor, both light are on due to the abs problem because the trac control uses the abs speed sensors to watch wheel speed so if the computer sees a problem with the abs it turns off the trac and turns on the light. after the abs is repaired the trac light will go out, start by having the codes read, a scan tool is needed to get the codes, there are many auto part stores that scan the computer for free but i dont know if they scan for abs codes, you will have to check that out. good day.
brake fluid light goes on when the fluid is low. The traction control light may go on as well if the module detects a fault in the traction control system. The abs light may go on at the same time as the trac light if the wheel speed sensor is not sending a believable signal to the abs/trac module.
If one of the wheel speed sensors is faulty, or a hub is bad, that can cause the problem described.
The ABS and traction off lights usually indicate a bad wheel speed sensor. I can't remember if the service light came on the three times mine went. The most common one to fail is the left front.
Try this cheap fix first.
Remove the left front wheel speed sensor, clean and reinstall it. They are magnetic and some times road debris will block the sensor. If that was the problem the ABS and traction lights will go off when you start the car.
Your second option is to have the shop scan the vehicle trouble codes, usually this costs an hours labor.
Well, try having the car hooked up to a diagnostic machine. The abs light usually comes on with the cavaliers. my wife has a 96, and the same thing happens with the abs. As for the etf light, I dont know what etf is. Is that suppsed to be atf? That would be tranny fluid if it is.
I will bet money that it is the ABS/TRACS module. It is mounted under the master cylinder on the bottom of the ABS unit. These are very, very, very common failures. I have replaced hundreds of them in my career. To answer your other question, the TRACS system uses brakes. For example: in the snow, when the L or R wheel is spinning faster than the opposite, the TRACS will apply brake to the spinning wheel to slow it down to an equal speed. Hope this helps.
no you need to take it and have the codes pulled on it, the abs system will disable the traction control system.Without knowing what the codes are for the abs system it would not be possible to say what the problem is.
did you get anyone to check the codes?
the trac off light will come on if the ignition module goes the module sits on top of the engine it has silver fins and is held in with 3 torx screws. it sells for about $100 so you might want to have someone diagnose this hope this helps
Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.
