MS908CV HEAVY DUTY

Autel MaxiSYS MS908CV — Heavy-Duty Commercial Vehicle Diagnostic Tablet (Original)

The MS908CV is Autel's original heavy-duty MaxiSYS tablet — the predecessor to the MS908CVII. It covers Class 3 through Class 9 commercial vehicles with bi-directional active tests, forced DPF regeneration, injector coding, and 19 service reset functions. The tool runs on a 9.7-inch touchscreen tablet with the MaxiFlash Elite J2534 VCI for wireless vehicle communication.

Note: The MS908CV has been superseded by the MS908CVII. The CVII runs on Android 10 with a faster octa-core processor, more RAM and storage, a higher-resolution display, and 25 service functions vs. 19. If you are evaluating heavy-duty tools, compare both before deciding — call us at 866-217-0063 and we will give you a straight comparison.

What the MS908CV Does

Commercial Vehicle Coverage — Class 3 Through Class 9

The MS908CV covers the full weight range of commercial vehicles from light-duty Class 3 trucks through Class 9 semis (10,000 LBS to 33,000 LBS GVW). It reads and erases fault codes across all available modules, displays live data, and performs bi-directional active tests on supported systems. AutoScan sweeps all available modules automatically. Auto-VIN provides fast vehicle identification.

• Class 1–9 diesel emissions system diagnostics and resets
• All 10 OBDII test modes (live data, freeze frame, enhanced Mode 6)
• AutoScan of all available modules
• Auto-VIN for fast vehicle identification
• FCA Secure Gateway access with Autoauth account

Bi-Directional Active Tests

Like the CVII, the MS908CV performs bi-directional component activation — commanding vehicle systems to activate, deactivate, or run specific routines. The component activation library has grown to 1,000+ functions via software updates. Key capabilities include:

• Forced DPF Regeneration — initiate regen cycles on demand
• Injector cutout tests — isolate individual injectors
• Injector coding — program replacement injectors
• Advanced coding and adaptations

19 Service and Maintenance Functions

• Oil Light Reset
• Maintenance Service Light Reset
• EPB (Electronic Parking Brake) service
• Brake Bleed
• DPF/Emissions system resets
• Additional service functions added via software updates

Expert Mode

Expert Mode provides direct access to OE-specific diagnostic system menus — bypassing the generic interface to access engine, transmission, and braking system parameters at the depth that factory diagnostic tools expose.

MaxiFlash Elite VCI / J2534

The MS908CV ships with the MaxiFlash Elite — Autel's wireless Bluetooth J2534 pass-through device. The Elite is the previous-generation VCI (vs. the MaxiFlash VCI included with the CVII). It handles all standard vehicle communication and J2534 pass-through programming functions wirelessly over Bluetooth.

Supported Protocols

• SAE J1939, SAE J1708 (primary HD protocols)
• CAN ISO 11898 (High-speed, Middle-speed, Low-speed, Single-wire)
• ISO 9142-2, ISO 14230-2, ISO 15765-4
• SAE-J1850 VPW, SAE-J1850 PWM
• K/L-Line, Flashing Code
• GM UART, UART Echo Byte, Honda Diag-H, TP 2.0, TP 1.6
• Fault-Tolerant CAN

Hardware Specifications

MS908CV vs. MS908CVII — The Honest Comparison

The MS908CV is the original; the MS908CVII is its direct successor with meaningfully upgraded hardware and software. Here is what changed:

• Processor: Quad-core 1.4 GHz (CV) vs. Octa-core 2.2/1.8 GHz (CVII) — the CVII is substantially faster
• RAM / Storage: 2 GB / 64 GB (CV) vs. 4 GB / 128 GB (CVII)
• Display: 1024 x 768 (CV) vs. 2048 x 1536 (CVII) — the CVII display is noticeably sharper
• OS: Android 4.4.2 (CV) vs. Android 10 (CVII)
• Service Functions: 19 (CV) vs. 25 (CVII)
• VCI: MaxiFlash Elite (CV) vs. MaxiFlash VCI (CVII — newer generation)

Diagnostically, both tools cover the same vehicle classes and perform the same core functions. The CVII does it faster, on a better screen, with more service functions. If you are choosing between them new, the CVII is the clear answer. If you already own the MS908CV and it is working, the TCP renewal ($1,295/year) keeps it fully functional.
