I searched the forum and found a tutorial on how to find the ECU code. After removing the plastic cover and poking the plastic I see the little **** I need to turn. It says to stick a flat head in the turn it counter clockwise to "Diagnostic". I can't fit a flat head screw driver in there. There is no grove for me to use the flat head. I try using a needle nose plier but I can't fit the pliers in that small hole to grip the edges. What can I do?
