Autel MS909 vs. MS919 vs. MaxiSys Ultra
Autel MS909, MS919, and MaxiSys Ultra are advanced diagnostics scanners that offer full OBD2 functionality.

Autel MaxiSys Ultra vs. MS919 vs. MS909: The Similarities

OBD2 Functions

Autel MS909, MS919, and MaxiSys Ultra are advanced diagnostics scanners that offer full OBD2 functionality. They can read and clear trouble codes, show freeze frame and live data, and the enhanced mode 6.

These scanners come bundled with the MaxiFlash VCI for the MS909 and MaxiFlash VCMI for the MS919 and MaxiSys Ultra. These devices provide fast Wi-Fi and network communications between the vehicle and the scanner.

In addition, MS909, MS919, and MaxiSys Ultra automatically detect VIN and select the car automatically for quick diagnostics. All three scanners support DTC analysis with expert repair advice from experienced industry professionals. Also, they provide repair tips and relevant cases.

If you want a device solely for OBD2 functions and a little help with repairs, you’ll like the MS909 since it’s the cheapest option of the three. Nevertheless, the MaxiSys Ultra has DTC troubleshooting with a video library.

It means you can have better insight into a repair procedure, so it’s more advanced than the other two. The added feature is not worth the extra hundreds of dollars. So, only if you want to have more ways to repair a vehicle is the MaxiSys Ultra ideal for OBD2 functions.

System Diagnostics

With these scanners, you can access all the available modules from all systems in supported cars. The devices have the topology module mapping feature, which color-codes the status of each system. As such, you’ll know which ECU module is malfunctioning in seconds.

Again, MS909 is the winner since it is not as expensive as the other two, but it offers similar complete system diagnostics functionality.

Advanced Service Functions

All three scanners support 36+ advanced repair and maintenance features. To this end, these scanners have all the most commonly used maintenance functions.

These include: Oil reset, DPF service, ABS bleeding, EPB reset, SAS reset, BMS service, and battery registration and reset. Additionally, these gadgets are capable of suspension reset, gearbox reset, IMMO service, and airbag reset.

Still, I’d go with the MS909 for advanced service features since it has similar services as the other two.

All scanners provide full diagnostics for 95% of post-2000 and 85% of post-2019 cars. Advanced system diagnostics, coding/programming, and bidirectional control are all vehicle-specific.

Autel MaxiSys Ultra vs. MS919 vs. MS909: The Differences


The main difference between these scanners is the hardware and a few functions that the MaxiSys Ultra supports but the other two do not.

The MS909 device comes with the MaxiFlash VCI vehicle connector, while the MS919 and MaxiSys come with the MaxiFlash VCMI.

While the MaxiFlash VCI only provides a secure connection and support for the latest protocols, the MaxiFlash VCMI is a 5-in-1 device. This gadget carries a 4-channel oscilloscope, multimeter, OBD2 CAN Bus Check, and waveform generator functions.

The MaxiFlash VCMI also provides ECU programming for Benz, Volvo, VW, and BMW. The tool acts as an RP1210 and J2534 compliant, PassThru programming interface. Nevertheless, MaxiSys Ultra has a docking station, but the MS919 does not come with one. You can connect the MaxiSys Ultra to any peripheral device effortlessly, unlike the other two.

You’ll like that MaxiSys Ultra provides split-screen functionality. You can see more features on a screen than on MS909 and MS919. This attribute is handy when comparing live data, as it makes it fast and easy to gauge vehicle performance.

Lastly, the MaxiSys Ultra has the largest memory at 256GB. This scanner has more space for storing more vehicle information, such that you don’t need to have a separate device for a customer’s vehicle history.

MaxiSys Ultra wins in special features since it provides well-rounded functionality. It offers professionals a long battery life and a superfast operating speed.
