Features and Functionality

Electronic Parking Brake (EPB) features


If you have ever been stuck on EPB lights and couldn’t disengage the parking brake, you will appreciate the Autel MaxiDiag MD805 scanner. 

You will notice that an ordinary scanner or code reader cannot reset EPB. However, Autel MaxiDiag MD805 Scanner has EPB reset feature. It will not only allow you to reset EPB but also diagnose the entire brake system. It can pinpoint the faults within the brake system. And once the fault is fixed, you can reset EPB with a single push of a button.


An operating error usually pops up when you are trying to clear EPB in some car models.

Oil Reset features


Knowing when to change your car oil can be a bit confusing if you have recently recalculated your millage. But with Autel MaxiDiag MD805 Scanner, it’s pretty easy to establish when you need to have an oil change.

Changing oil at the right time is the best way to cut on maintenance and repairs.

Besides, your car’s performance will significantly improve when your car engine is running on clean oil. Once you have replaced your oil, then you need to reset the oil lamp. The good news is that Autel MaxiDiag MD805 Scanner allows you to quickly reset the oil lamp with a single push of a button.

Other than resetting the oil lamp, the oil reset feature will detect other faults that may result when the oil drops below the recommended levels. Such issues include elevated engine temperatures and increased friction within the rotating components.


When performing oil reset functions, you often encounter vehicle linking errors. This problem will prompt you to turn off the ignition for ten seconds and turn it on again.
