A few years ago I had a CEL that would not reset.
I tried the battery disconnect, but that didn't work.
So I purchased a ScanGaugeII tool that was supposed to read codes and be able to reset the light with the push of a button. That didn't work either.
I called the manufacturer of the ScanGaugeII tool and told them it would not reset the light. They gave me a detailed description of a different way to reset the light. I still needed the scan tool, but had to program in a bunch of different numbers as opposed to just pushing a button once.
In the end, with their guidance, it reset the light.
