Overall Features And Functions

The Oxgord MS309 has a very basic diagnotic funtionality
The OxGord MS309 is very basic in its diagnostic functionality

The OxGord MS309 is very basic in its diagnostic functionality. You’ll get the option to read or clear basic diagnostic trouble codes, read freeze frame data, run an I/M readiness test, or retrieve vehicle information. 

Comparatively, both the Ysding JD101 and the Autel AL319 have more robust options, including the option to view the live data stream. The Ysding JD101 also reads manufacturer-specific codes for most car manufacturers. 

Extra Features And Functions

One helpful extra function you’ll find on both the Autel AL319 and the Ysding JD101 is a DTC lookup library. This way, you can find out what the codes mean right on your scanner, rather than taking the extra step of seeking them out online. 

Additionally, the Ysding JD101 includes a battery tester. This can show the voltage of your vehicle’s battery in real time, showing when it’s time to recondition or replace it. 

Supported Protocols

The Autel AL319 supports all current OBDII protocols, including CAN. The Ysding JD101 supports 5 protocols, including ISO9141, KWP, CAN, J1850 PWM, and J1850 VPW. The OxGord MP309 supports a similar range of protocols, though it lacks compatibility for ISO9141. 

Supported Vehicle Makes

The OxGord MP309, Ysding JD101, and Autel AL319 will work on any vehicle that has an OBDII port. This includes the majority of vehicles made in the United States after about 1996. In addition, the Ysding JD101 supports any EOBD car from the European Union made after 2000.

Software And Updates

The OxGord MS309 doesn’t require updates. If you have an issue with the software, you can reach out to the manufacturer for help and information. 

Updating the Autel AL319 is easy. Simply download the update client from the company’s website, which you can do on any computer. Users report no difficulties obtaining or installing the update file

Things can be trickier with the Ysding JD101. It requires an older-style USB cable to connect to the computer, first of all. Some users also report difficulty installing and using the update client, as well as difficulty communicating with newer vehicles until the update is successfully installed. 

Reliability

The Autel AL319 gets the highest marks across the board for long-term reliability. The easy updatability mentioned above is part of this. The housing is also very sturdy and easy to hold while you’re working, which helps avoid drops and other damage. 

While most people have no issues with the Ysding JD101, those who do have issue tend to get quite frustrated. The company’s support is not the best, so keep that in mind if you need to reach out for help.

Finally, the OxGord MS309 is a workhorse of reliability when it comes to performing the functions it promises. Just keep in mind that the lack of available updates could limit its use with newer vehicles as OBDII protocols change.

FAQs

Q: Can the OxGord MS309, Ysding JD101, or Autel AL319 read SRS, ABS, or transmission codes?

No. These OBD2 scanners are designed only for OBD2 diagnostic trouble codes. The only diagnostic trouble codes you’ll see related to the transmission or brakes are those triggered by your engine computer as part of OBDII protocols. 

Q: What is the difference between “generic” and “manufacturer-specific” codes?

Generic codes are designed to have the same basic meanings for all vehicle makes and models. These codes tend to start with P0, P2, P3, or U0

Manufacturer-specific codes are set by certain vehicle makers when none of the generic codes available fit a given problem. These will often start with P1 or U1, though some P3 codes are also manufacturer-specific. These codes can be read by the Ysding JD101.

Q: Will clearing all the trouble codes turn off the check engine light?

It will initially, though the light may turn back on if the code triggers again. Diagnostic trouble codes typically indicate a problem within your engine that needs to be fixed. Once you’ve addressed the underlying issue, clearing the trouble codes will turn off the check engine light. 

Q: How do the OxGord MS309, Ysding JD101, and Autel AL319 get power if they don’t have a battery?

These devices gain power directly from your engine while plugged into the OBDII port. In order to turn them on, put your key in the ignition and turn the key to “on” without starting the engine, the same way you would to turn on electronic systems like the radio or headlights. 

Q: How do I know if the OxGord MS309, Ysding JD101, and Autel AL319 will work on my vehicle?

These scanners will read codes from any vehicle with an OBDII port. This port will generally be found on the underside of the steering column, or somewhere else inside the driver’s side passenger area. If you want to make sure your vehicle is supported before you buy the device, you can contact the manufacturer with your vehicle’s information.
