Autel OBD2 scanner MD806

Getting the most from it

Some drivers only need a basic code reader to see why the check-engine light is on, others want to look at several vehicle systems and access selected service resets. The Autel MaxiDiag MD806 is aimed at the second group, with diagnostic coverage for the engine, ABS, SRS and transmission on supported vehicles. Its listed vehicle coverage is up to 2015, and functions vary by make and model.

For example, if an ABS warning appears, you can use the scanner to read and clear available fault codes and view live data, rather than relying on the warning light alone. That can help narrow down what needs further attention, but it does not replace a repair manual or confirm a diagnosis by itself. Without having tested it, the key practical point is that its usefulness depends on compatibility with your particular vehicle.

Why it’s worth it

The broader system access is the main reason to consider this tool over a simpler engine-only reader. It can access ABS and airbag modules as well as engine and transmission systems, and it supports live data and freeze-frame information. The listing also describes all 10 OBD-II test modes and the ability to print a diagnostic report, which may be handy when keeping records or sharing scan results during a repair.

It also offers selected service functions: oil reset, EPB reset, SAS reset, DPF regeneration, battery registration, throttle relearn and air-fuel-ratio reset. These are not universal features across every vehicle. The scanner does not support ABS bleeding, so anyone specifically looking for that procedure should choose a tool that lists it. It suits you if you want one device for fault-code checks and several maintenance-related functions, it isn’t for you if you need guaranteed coverage for a newer vehicle or a particular unsupported procedure.

Key features

The MD806 reads and clears codes in supported engine, ABS, SRS and transmission systems, and can show live data from multiple sensors. The listed OBD-II functions include emissions-related checks, freeze-frame data, oxygen-sensor and onboard-monitor tests, component tests, vehicle information and module identification. What appears on screen will depend on the vehicle and the systems it exposes to the scanner.

Software updates are described as free for the lifetime of the device and are performed through an internet connection. Before choosing it, match your vehicle’s year, make and model, then confirm the exact function you need is supported. The product information recommends providing the VIN for a compatibility check, that matters here more than the headline list of resets, since not every vehicle supports every service function.

When to choose it

If you prioritize wider system access and service resets in one scanner, the MD806 has a more specific purpose than a basic code reader. If you prefer a straightforward tool just to check engine codes, its extra system coverage may not add much for your needs. Te conviene si your vehicle is within the stated coverage and you have confirmed the functions you plan to use. No es para ti si your car is newer than 2015, you need ABS bleeding, or you cannot verify compatibility first. For a DIY owner investigating warning lights or a mechanic checking supported vehicles, that compatibility check is the deciding step—not the number of functions on the box.
