Autel MaxiCheck MX808S – All-System Bi-Directional Diagnostic Scanner with 28+ Service Functions
The Autel MaxiCheck MX808S is a professional compact automotive diagnostic tablet designed for independent workshops, mobile technicians and automotive users who need more capability than a basic OBD2 code reader without moving into a large flagship diagnostic platform.
It combines OE-level full-system diagnostics, bi-directional active testing, supported coding and adaptations, AutoVIN vehicle identification and more than 28 maintenance and reset functions in a portable 7-inch Android diagnostic tablet.
The wired diagnostic connection provides stable communication during scanning, active tests and service work, while Android 11, a 1.8GHz quad-core processor, 4GB RAM and 64GB internal storage provide a responsive interface for everyday workshop diagnostics.
OE-Level All-System Vehicle Diagnostics
The Autel MX808S provides diagnostic access to available electronic control systems throughout supported vehicles, giving technicians a much broader view than a standard engine-code reader.
Diagnostic functions include:
- Read diagnostic trouble codes
- Erase fault codes
- Retrieve ECU information
- View freeze-frame information
- Display live vehicle data
- Graph selected data parameters
- Record and review live data
- Perform active tests
- Access supported coding and adaptations
- Perform vehicle-specific service procedures
Depending on vehicle configuration, accessible systems can include Engine, Transmission, ABS, SRS/Airbag, Electronic Parking Brake, BMS, Steering, TPMS, HVAC, Body Control, Instrument Cluster and other installed control modules.
Bi-Directional Control & Active Tests
One of the most valuable workshop functions of the Autel MaxiCheck MX808S is its bi-directional control capability.
Instead of simply reading a diagnostic trouble code and guessing which component has failed, the technician can send commands directly to supported modules and actuators to check whether they respond correctly.
Depending on vehicle support, active tests can include:
- Cooling fan operation
- Fuel pump activation
- Injector tests
- Interior lighting
- Exterior lighting
- Horn activation
- Door lock actuators
- Power windows
- Electronic parking brake operation
- A/C clutch operation
- Throttle functions
- Relays and solenoids
- Additional manufacturer-specific component tests
This can help workshops identify electrical, actuator and control problems faster and reduce unnecessary parts replacement.
28+ Service & Maintenance Functions
The Autel MaxiCheck MX808S provides more than 28 commonly used service and maintenance functions for compatible vehicles, making it suitable for routine workshop servicing as well as diagnostic work.
Popular service functions include:
- Oil Service Reset
- Electronic Parking Brake Service
- BMS / Battery Registration
- Steering Angle Sensor Calibration
- DPF Regeneration
- ABS Brake Bleeding
- Injector-related service functions
- Throttle Adaptation
- Airbag-related service functions
- Transmission Adaptation
- Suspension functions
- Headlamp functions
- Crankshaft Relearn
- Tire-size related functions
- A/F Setting
- Additional manufacturer-specific procedures
Available service functions vary by manufacturer, model, model year and installed vehicle systems.
Coding & Adaptation Functions
The MX808S supports coding and adaptation functions on compatible vehicles, providing additional workshop capability beyond code reading and service resets.
Vehicle-dependent functions may include:
- Component adaptation
- Replacement component matching
- Parameter initialization
- Vehicle-specific relearn procedures
- Selected coding functions
These functions vary significantly by vehicle and should not be confused with full OEM ECU programming available on Autel’s higher-level programming platforms.
AutoVIN Vehicle Identification
AutoVIN technology can automatically identify supported vehicle information and reduce the amount of manual vehicle selection required before diagnostic scanning begins.
This helps technicians move quickly from connecting the scanner to accessing the correct diagnostic software and vehicle systems.
Live Data, Graphing & Recording
The MX808S can display real-time ECU data in text and graph formats to help technicians diagnose problems that may not be obvious from stored fault codes alone.
Available parameters can include:
- Engine RPM
- Coolant temperature
- Throttle position
- Fuel trim
- Oxygen sensor information
- Battery voltage
- Wheel-speed information
- Transmission data
- Additional system-specific values
Live data can also be recorded and reviewed, helping technicians investigate intermittent faults and compare vehicle behavior under different operating conditions.
Basic TPMS Service Capability
The standard Autel MaxiCheck MX808S provides basic TPMS-related service capability on supported vehicles.
However, it is important to distinguish the MX808S from the MX808S-TS. The standard MX808S does not provide the complete sensor activation, MX-Sensor programming and comprehensive TPMS health-check functions of the TS version.
Workshops that regularly replace, program or relearn TPMS sensors should consider the MX808S-TS or MX900TS instead.
FCA AutoAuth Support
Supported FCA vehicles equipped with secure gateways can be serviced through AutoAuth when the required account, authorization and applicable software are available.
This can allow authorized diagnostic operations and active tests on newer supported Chrysler, Dodge, Jeep, Ram and other FCA vehicles.
Stable Wired Diagnostic Connection
The standard MX808S connects to the vehicle through a wired diagnostic cable.
For workshop technicians who prioritize stable communication and do not require wireless Bluetooth operation, the wired design provides a simple and reliable connection while keeping the cost below many wireless Autel platforms.
7″ Android 11 Diagnostic Tablet
The MX808S combines professional diagnostic software with compact workshop hardware.
- Android 11 operating system
- Rockchip RK3566 / Cortex-A55 processor
- 1.8GHz quad-core processing
- 4GB RAM
- 64GB internal memory
- 7″ capacitive touchscreen
- 1024 × 600 resolution
- 5000mAh rechargeable battery
- Dual-band Wi-Fi
- USB connectivity
- Expandable storage
Broad Multi-Brand Vehicle Coverage
The Autel MaxiCheck MX808S supports a broad range of US, Asian and European vehicle manufacturers, making it suitable for multi-brand repair shops and technicians who regularly service different makes.
Vehicle coverage, active tests, coding, adaptations and maintenance functions vary according to manufacturer, model, year and installed control systems.
Videoscope Compatibility
The MX808S can be paired with compatible Autel videoscope accessories for visual inspection of difficult-to-reach areas such as engine compartments, cylinders and enclosed mechanical spaces.
This gives workshops the option to extend the scanner beyond electronic diagnostics when visual inspection is also required.
2 Years Free Software Updates & 1 Year Warranty
The Automax Tools UAE package includes 2 years of free software updates and a 1-year warranty.
Regular software updates help maintain vehicle coverage, improve supported diagnostic functions and add newer vehicle applications as available.

The Autel MX808S is suitable for:
- Independent automotive workshops
- Mobile mechanics
- Automotive diagnostic technicians
- Automotive electricians
- Small and medium repair shops
- Used-car inspection businesses
