China OBD2 Tools on

Nov 26

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 struck 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.

GODIAG GT100 OBD2 Breakout Box is a new ECU connector and protocol communication detection device, which is convenient for technicians to connect with ECU module separately for diagnostic programming and coding. It can also be used to detect whether the diagnostic programming or decoding device can send the communication signal normally.

What highlights does the GODIAG GT100 auto tool have?

1. Diagnostic device detection
When connecting with GODIAG GT100, the diagnostic device will emit communication signals after the vehicle model and function was selected. The protocol indicator on GODIAG GT100 flashes, if not, it means there was something problem or damage in the diagnostic device connection.

2. Communication status display
Connect GODIAG GT100 to the OBD port of the vehicle and turn on its power switch, the vehicle battery voltage will be displayed. The protocol indicator on GODIAG GT100 will flash when connecting with an additional diagnostic device, which is convenient to observe the status and communication protocol of the current vehicle.

3. Fast connection with a single module and diagnostic device.
GODIAG GT100 can quickly connect to a single ECU module for communication and programming with a diagnostic device. Technicians are allowed to finish work in an office, no need to test in a car in case of any possibilities of data loss from other modules.

4. Multiple car ECU modules connection
It is designed for technicians those require to connect with multiple ECU modules when programming, such as key programming.

5. Continuous power supply when battery replace
Connect with GODIAG GT100 via OBD before battery replace, which can give continuous power supply for ECU to avoid failure or remote data losing of specific cars due to this reason.

6. Diagnostic wire was extended to 1.2 meters
1.2 meters length wire solves the troubles of diagnostic wire was too short, or vehicle interface was too narrow for connection.

7. Banana plug jump can connect with OBD1 interface
GODIAG GT100 supports converting OBD1 interface to standard OBD2 interface via connecting with banana plug and jump wire, which provides convenience for OBD1 vehicles’ diagnosis.

8. Special truck interface convert to standard OBD2
GODIAG GT100 also supports converting special truck interface to standard OBD2 truck interface via the protocol.

9. BMW CAS4 special connection wire
GODIAG GT100 is a BMW CAS4 adapter test platform as well, which can detect programmed keys and CAS4 normal work.
Even though GODIAG GT100 ECU Connector is already with such features, GODIAG engineers are working for developing more functions, such as specific Benz EIS connector, ESL connector, IMMO matching wires, … etc.
