Tried doing this on my own because I do remember reading about checking different things in each of the 5 modes. But the Chiltons book mentions something about using a screw driver to turn a selector switch to 1 of 3 settings. I do see a slotted dial thatsays something to the effect of Idle settings and as you turn the dial that idle progresses to a higher setting. if you turn it fully clockwise though there is at the end a small section where it says "diagnosis". When I turn it to that point that is where the green and red lights start to flash.I'd like to get to Mode III which is where the fault codes are stored. How do I get to moe III. I don't see any selector switch.
