Seeing the check light on your dashboard illuminate is enough to strike fear into anyone. While the LAUNCH X431 PRO TT is capable of clearing the code, you can only do so after resolving the issue. If you clear the code without resolving the issue that triggered it, there is a good chance that the check light will illuminate again.
