Autel MS906S vs. Autel MS906CV vs. Autel MS908CV
The MS906S, MS906CV, and MS908CV are professional scanners that support full system diagnostics.

Autel MS908CV vs. MS906CV vs. MS906S: The Similarities

OBD2 Functions

As expected of professional scanners, they all support On-board Diagnosis. However, unlike the others, the Autel MS906S additionally supports OBD1 Diagnostics.

For their respective vehicle ranges with OBD2 engines, they offer full OBD2 functions across all 10 test models.

System Diagnosis

In today’s market, automobile scanners that can run OE-level system diagnostics are the norm. Thankfully, the MS906S, MS906CV, and MS908CV support full system diagnostics.

Such a feature will enable you to perform system checks and thoroughly go through all DTCS. On top of that, you’ll also get access to other forms of data from health status reports and waveform data streams.

Hardware Expansion Compatibility

Hardware expansion compatibility is an underrated feature. You need an automobile scanner that can cooperate with other tools for in-depth diagnosis. Fortunately, all these scanners have hardware expansion compatibility.

The Autel MS906S, MS906CV, and MS908CV scanners support almost all extension modules like oscilloscopes, endoscopes, and multimeters. Specifically, we have the MV400, MV108, and MV105.

Autel MS908CV vs. MS906CV vs. MS906S: The Differences

Advanced Service Functions

The Autel MS906S Auto Scanner is an improvement upon several other pre-existing scanners, including the MS906BT, MS908, and MK908. Besides being faster, it also comes with all the advanced functions you’d expect from a professional scanner. On top of that, since it’s the latest in its range, it will receive additional service functions via future software updates.

Next, we have the Autel MS906CV Heavy Duty Auto Scanner. It comes with a limited number of advanced service functions (25). Therefore, it lacks crucial ones like Parameter Setting, Timing Calibration, Trans Adaptation, and Automatic Transmission Clutch Calibration.

Finally, we have the MS908CV Heavy-Duty Diagnostics Scanner. It offers 25 advanced services and an additional 23 adaption functions that make it better than the MS906CV.

Advanced service functions for passenger vehicles include:

  • Gear Box Calibration.
  • Injector Coding.
  • Throttle Matching.
  • DPF Regeneration.
  • ABS Bleeding, BMS.
  • Oil Reset.
  • Brake Reset.
  • SAS Calibration.
  • TPMS, among others.

Advanced service functions for commercial vehicles include:

  • Fuel Pressure.
  • Adaptation Reset.
  • DOC/DPF Replacement Reset.
  • Injector CEOM Calibration.
  • Boost Calibration.
  • Timing, Calibration.
  • O2 Sensor Calibration.
  • Injection Quality Adjustment.
  • DSI System De-Aeration.
  • After-treatment Maintenance.
  • Boost Calibration.
  • After-treatment SCR Catalyst Cold Soak Override, among many others.

NOTE: For Autel Diagnostics Scanners, not all special functions are universally compatible. Therefore, before purchasing, we advise you to first send your vehicle’s VIN directly to their response team for verification ([email protected]).

Coding and Programming

All three scanners are capable of auto diagnostics coding and programming. However, there are degrees to which each scanner can effectively code and program.

The Autel MS906S is capable of local-smith ECU coding. It can perform advanced operations like:

  • Adaptive data reprogramming.
  • Reinforcement of performance issues related to driving, fuel efficiency, and power loss, among many others.

On top of that, it can also flash to unlock or disable hidden features like US-style daytime running lights, foldable mirrors and custom interior lights.

We then have the Autel MS906CV. Unlike the MS906S, it can only support basic programming operations. Therefore, it lacks ECU and other advanced programming functions.

Finally, we have the MS908CV. Like the MS906S, it can handle advanced ECU programming operations.

We recommend the MS906S as it is the more advanced scanner in this category and also at the cheapest price.

Bi-directional Control

The MS906S and MS908CV Auto Scanners both allow for Active Test Bi-directional Control. It’s a crucial feature allowing professionals to operate, test, and switch between two-state systems. It generally saves a lot of time and effort.

Unfortunately, the Autel MS906CV lacks this feature.
