Seems to be running  good.

I dont see codes anywhere on display. It's not blinking in any pattern  just steady blink. Goes out If I hit kill switch and ignition  is still on.

Just put rings and headgasket in 21 600 touring. After getting  back together  two relays blown and when it's running  light is just steadily flashing. Any help would be nice I ordered fault  reader to day.
