Arthur,
The tool checked out perfectly per your instructions. I went back to the test with yellow pin on 14, black on #1 and red on #16. With ignition on, pressed the switch and got a solid red LED. Held it for 3-5 secs, closed switch and the LED went out. Did the same on pin #8, full red, no blinking, as long as the switch was energized. Does this mean that there are NO codes stored? Or am I a "blinking" idiot! I've lead a very technical life and this has me puzzled.
