Wouldn't this be dangerous? Because you erase the code but don't fix the problem?

    When I scan mine car, I do the same as this guy. But I leave my scanner plugged in as its erasing the codes. The CEL goes away after a few seconds.

    Hes probably showing how to scan/erase codes after fixing the problem. Guess he forgot to address that.

    Yes, as long as the engine isn't running. At least that's how mine's always worked...

    My Ride: a car
    I use the Snap-on Scanner, which gives data as well. You should not unplug while erasing. The CEL stays on in both key 1 and 2 if you have code. After clearing the codes, post repair I like looking at the data to make sure i am right about what i fixed
