FAILURE: ETS BOARD LIGHTS DIRECTED

Hello, how are I hope that my car is a cavalier Z-24 American Mod 97 Motor 2.4 The fault it presents is that the ETS lights light on the board (assisted traction system) but they turn on after walking for a while and do not turn off the only fault that I notice the car is that after the lights turn on when under the speed as it is pulling a little, I hope you can help me to solve the problem.

Good afternoon you have to check the AyB sensors of the box thanks

Thanks for your answer to check the sensors, do not take the box or if so that I do not use the mechanic

Thanks for the data, the mechanic tells me that it does not deal

Good evening, to check the signs you do not have to come the transmission, only on the side of the steering wheel removes everything of the suspension (Trans arrow shock absorber From the day it does not give you problems you are going to save that the problem is in the transmission (the sensor) or does it cost you anything to say that?
