.. That is a SAD news to hear!! Hope somebody can prove otherwise.
How did you figure out the dimmer issue? I realized that the buttons(ENG, TRAC, etc.) aren't lit.
I'm pretty sure my wires check.
Do you have any idea what do a4, a8, and b10 do?
(edit:
a4: check tire pressure
b10: fuel level input)
What the heck is vf park ???
..so confused. Spent 5 hours and stuck on dreaded blinking 0.0!
