Autel MD806 Pro Review: Portable OBD2 Tool Must Have

Here is the Autel MaxiDiag MD806 Pro diagnostic tool I got yesterday. I have not used it before, this is definitely a lot more portable than I thought. My Chevrolet truck has a check engine light on, so I’m gonna use the small tool to find out the reason.

Alright, I will use the little connector to plug-in the OBD2 port for a certain thing. Autel MD806 Pro is not a touchscreen, it is a kind of old-school that should hit the buttons. It is actually very simple to use.

Let’s find out why this check engine lights on and hopefully it is not anything too crazy… so the good news is it only shows one code found. Let’s read codes, it will do stored codes. It says a fan speed sensor circuit. I am not entirely sure what the fan speed sensor circuit is, but that is when we’re gonna have to look up. The code is P0526.

So let me check that out, but before I do that let’s just go through the diagnostic manual for a quick overview: system status, read codes, erase codes, live data, freeze frame, I/M readiness, O2 monitor test, onboard monitor test, component test, vehicle info, modules present, DTC lockup, system status. Okay, that is all. Let’s go out of this, they are all in OBD2 function.

In the main menu, there is a service function, it is including oil reset, EPB, SAS, DPF, BMS, even your throttle. And go out of this, there is an update, as you see, it is updated by USB, not Wi-Fi.

All right let’s go check out that code and find out exactly what it is. It turns out that is the electric fan clutch. It’s really no big deal, it is not expensive, and not difficult to replace. The truck doesn’t overheat. It seems to do just fine, it’s something maybe we’ll fix.

Autel MD806 Pro is quite a small and powerful OBD2 scanner that every mechanic can carry easily and put in cars anywhere. It has the basic functions for my daily work, and helps me a lot for home service.
