There will always be a code if the light is on - at the same time when the light is on that means the feature is unavailable, so there is always a reason. Maybe the scan tool is not powerful enough to read the code. In any case, you can try a general "clear" with the scan tool or disconnect the battery for 30 minutes and see if that fixes the problem. If you clear the codes and watch the light go out, then come back on immediately (1 second), then the problem is more than likely electrical.
