oil help

Today i did an oil change on a 99 granx prix. The Change oil soon light was on and after i changed the oil the light didn't go off. I know there is a certain code you can do. You have to hit the gas pedal a certain amount of times. I'm not sure how it goes. If anybody can let me know that will be very helpful. Thanx, Jordan

Turn the key on (do not start engine), depress the gas pedal to the floor 3 times within 5 seconds. Turn key off. When you turn the key back on, the DIC should flash, then reset to 100% oil life.

thanks
