You'll have to search for the list of codes what the code numbers mean (I found then on line).
The "Check Engine" light may shut off if the system doesn't detect an error for 3 consecutive checks. If it doesn't, the light will shut off if the battery voltage gets too low (like a weak/dead battery or removing a battery cable).
Yup, that's what I did but got no codes, just 6 tones or bongs. I've tried it several times and always get the same thing. I'm taking it monday to the lot where I bought it while it's still covered by my warenty.
