I get P1680 code when only using scanner. The editor works fine when I change the fan and transmission setting.
I connect scanner and as soon touch accelerator the code pops up. Therefore, I cannot use scanner to record, because it is in reduce power mode.
So I clear code, I test drove and everything works well. I increase my MPG from 16.2 to 18. I have better transmission shift.
Any clues how to overcome P1680 code?
