Chevrolet Cruce 2012 Ecotec 1.8 Automatic Failure

Someone who can help me please, a yellow witness of a car with a key was turned on, (he did not turn on the check Engine or any code in the message center), I connected a scanner of those who have a car zone and did not indicate any error but when he was erased by erase the error code the witness was turned off and turned back to the 3 seconds, then I connect another scanner. 00,05,99
I did the tuning service: Change spark plugs, air filter, oil and filter, wash acceleration body and lave Little more time as in 1 minute. I already tried to disconnect the 5 min battery. And turns on the witness again. The vehicle does not present any failure when circulating in high or low.

Hello the light that turns you with the key is because of the change of filters and oil you must reset it with the factory scanner that at 10 thousand will happen to you the same luck
