Question: What action should I take if the check engine light turns off before I reach the car repair shop?
Answer: If the check engine light disappears on its own, then you should do nothing. This is a sign that the problem that caused the light to come on has been addressed. Hence, it should not be taken as a faulty OBD2 system. It may also be a sign that a loose gas cap was tightened or a fouled spark plug was cleared. And until the light comes on, your car doesn’t require any special attention.

Question: What problem should a diagnostic scanner detect?
Answer: This depends on the type and quality of the diagnostic scanner. If the unit is advanced, it will cover basic, special, and advanced functions. But if it’s not, then it will only cover basic and a few special functions. Some of the tests that a scan tool covers include read and erase codes, live data, freeze frame data, oil reset, and much more.
