Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.
SOURCE: Impala - trac off and ABS light along with service traction syst
THE PROBLEM IS WITH A HUB WHEEL SPEED SENSOR OR MORE LIKELY THE HARNESS LEADING TO THE HUB.
CHECK THE RESISTANCE AT THE HUB CONNECTION, IT SHOULD BE BETWEEN 900OHMS AND 1300OHMS. THEN SWITCH TO A-C VOLTAGE, IT SHOULD BE 100MV WHEN TURNING THE WHEEL BY HAND. IF BOTH CHECK OUT THE PROBLEM IS IN THE WIRING TO THE HUB.
THE RIGHT FRONT HUB USUALLY HAS A BEND, DOWNWARD THEN UPWARD NEAR THE CONNECTOR TO THE HUB. THAT IS WHERE THE PROBLEM USUALLY OCCURS.
NEW HARNESS WIRES CAN BE BOUGHT AT THE DEALER.

Hi,the traction control light coming up means there is a fault detected in the system and a scan tool will be required to learn what fault has been detected. Possible steering angle sensor, wheel speed sensor or brake pressure sensor since the light comes up when making turns or when backing up. Faults are to be checked and proper diagnostic procedures carried out before parts replacement remedies.....

All are tied into the ABS system, traction as well as stabilization, This needs to be looked at by someone who can hook up a diagnostic tester to read the fault codes stored in the ABS system then perform the correct diagnostic procedures to isolate the problem

Traction control only works when one wheel is spinning faster than the other it trys to even them out so it wont spin...sometimes if one of the wheels come off the ground in an uneven area or if you take a turn too fast and one wheel turns when the other one dont it is designed to operate.
I would remove all wheels and check the braking system...Is it 4 wheel disc or rear drum ?
If it has rear drums you could have a wheel cylinder leak that will sometimes lock the wheel because of fluid contamination....This would cause both lights to come on...If you find no problems
sometimes the abs sensor builds up fragments on the magnet and makes the light come on...
or if the abs sensor is not close enough to the exciter ring it will make the light come on because it will be out of adjustment.....all you do is press the sensor inward until it barely touches the ring and it will adjust itself....You can sometimes clean the magnet if it is contaminated and make the light go off ( only after you reach 6 to 15 mph. it will go off ).If it dont go off you have to buy a sensor.
Also make sure all tires have same amount and plenty of air to keep vehicle in balance/level.
