This is an interesting one. Check engine light has been on for a few weeks.
I put my diagnostic pin in 19 but there is zero flashes, as if there is no communication with the diagnostic module.
The small 8 hole push button diagnostic thing does light up, although it does not give any flashes when I hold it down for 3 seconds.
Now the CEL flickers while I drive.
Any idea where the pin 19 were actually goes to? So I can trace what's going on?
