Hi jesushonda,
I believe it is the brake lights that are staying on. Check the brake switch at the pedal. Most probably the stopper for the brake switch has disintegrated causing the brake switch to remain on all the time.
The D4 indicator blinking indicates an error has been detected by the transmissin control system. You would need to retrieve the trouble code to know what is causing it.
Is the speedometer working?
