FAQ

Question: What should I do if the “check engine light” goes off before taking the car to the mechanic?
Answer: In most cases, you should do nothing at all. If the issue that made the check engine light come is rectified, then the OBD II computer will turn the light off. This is not a sign of a bad OBD system. As a matter of fact, the car computer system is performing its duty by verifying that an issue temporarily existed but has since been rectified. At this juncture, your car requires no special attention unless the light comes on again.

Question: What should I do if the light stays on after clearing the error codes?
Answer: You shouldn’t panic at all. This is a sign that your car needs to be checked and some parts fixed. After driving, you should ensure that the gas cap is not missing or loose. Constantly turn off your engine when refueling. And when the light does not turn off after a few short trips after you’ve replaced the gas cap or tightened it, then, you should take your vehicle for service instantly. If you delay, this might cause more problems.

Question: Does Autel provide free updates and upgrades on its OBD2 scanners?
Answer: Yes, it does. Though, this varies from one Autel scanner to another, with a good number of them having one year of free updates. Some Autel scanners say that they offer a lifetime of free updates, but many users say this is not true.
