So, if you want to get the most out of the tool, you need to know when to use it.
In fact, the most basic diagnostic tools will only spew nonsense code at you when the Check Engine light is on. If it does, that means the built-in AI has gotten a little too intelligent. It's not going to fix a flat or replace a windshield.
When to Use a Diagnostic Toolĭon't make the mistake of thinking a diagnostic tool is a magical solution to fixing all of your vehicular troubles.
Using an onboard diagnostic ( OBD-II) scan tool will give you an extra way to find and fix problems while feeling like a professional mechanic at the same time. Now what? Before you reach for a conveniently-placed torque wrench to try the ol' 'love tap,' hook up a diagnostic tool to get a little bit more intel on what's going on. You hear a new, disturbing noise coming from your engine, open the hood, look around, and find nothing.
