long blink, long blink, short blink, short blink, short blink.
JDM first gen B16a with matching PW0 ECU. That should be 23 but it isn't a real code. There is no pause between the blink except for a long pause when the sequence starts again. I cut ignition and turn the car back on and it goes away and does not come back. Seems to happen when I am low on fuel.
