Important

Not every control module or diagnostic function is available on every vehicle.

System availability depends on the model, production year, engine, transmission, ECU specification, vehicle equipment, software version and any manufacturer security restrictions.

A vehicle being supported for general diagnostics does not mean every system or function listed for the MB V3.0 platform will necessarily be available.

Bi-Directional Active Testing

The MB V3.0 supports bi-directional control, also known as active or actuator testing, on compatible vehicles.

Rather than simply reading information from the vehicle, the scanner can send commands to supported electronic components and monitor their response.

Depending on the vehicle and control module, active tests may include:

• ABS pump operation

• Window regulators

• Fuel pump

• Wiper and washer motors

• EGR valve

• Fuel injectors

• Cooling fans

• Transmission solenoids

• Other supported actuators and electrical outputs

Active testing can help diagnose faults by checking whether a component responds correctly when directly commanded by the diagnostic tool.

Active-test availability varies by model, production year, ECU and vehicle specification.

Important – Service Functions Vary by Vehicle

The MB V3.0 does not provide all 39 functions on every vehicle.

Available functions depend on factors including:

• Vehicle model

• Production year

• Engine

• Transmission

• ECU specification

• Factory-installed equipment

• Software version

• Communication protocol

• Vehicle security restrictions

Some supported vehicles provide a large number of service functions and active tests, while others provide considerably fewer.

For example, the fact that the MB V3.0 supports DPF regeneration, battery registration, injector coding or air-suspension calibration as platform features does not mean each of those functions will be available on every supported Mercedes-Benz, Sprinter, Smart or Maybach vehicle.

If a particular specialist function is essential to your intended use, check the latest iCarsoft vehicle and function coverage information before ordering.

Advanced Adaptation & Teach-In Functions

On supported vehicles and control modules, the MB V3.0 also provides access to advanced adaptation and teach-in procedures.

These may include functions such as:

• Intake-valve calibration

• Oxygen-sensor calibration

• NOx-related learned-value resets

• SCR-related teach-in procedures

• Camshaft-position teach-in

• Pedal-angle sensor teach-in

• Intake-port shutoff teach-in

• Wheel-electronics identification

• Other supported manufacturer-specific adaptations

These functions are highly vehicle and ECU dependent and should only be performed when the operator understands the required procedure.

Air Suspension Service

On compatible Mercedes-Benz vehicles equipped with electronically controlled air suspension, the MB V3.0 may provide functions including:

• Fault-code reading and clearing

• Suspension calibration

• Ride-height adjustment

• System reset

• Initialisation procedures

The exact procedures available depend on the vehicle and suspension control system.

Battery Management

On supported vehicles, battery-management functions may include:

• Battery condition information

• Replacement battery registration

• Battery-management reset procedures

• Sleep-mode activation

• Related battery service operations

Requirements vary between vehicles and battery-management systems.

DPF Functions

On supported diesel vehicles, DPF functions may include:

• DPF regeneration

• DPF-related relearn procedures

• Component replacement initialisation

• Relevant DPF service resets

DPF regeneration should only be performed when vehicle condition and operating circumstances are suitable and the operator understands the procedure.

DPF functionality is not available on every diesel vehicle.

AutoVIN Vehicle Identification

On compatible vehicles, the MB V3.0 supports AutoVIN identification.

AutoVIN can automatically identify relevant vehicle information after connection, helping speed up vehicle selection and reduce manual data-entry errors.

Availability depends on the individual vehicle and ECU communication protocol.

Where automatic identification is unavailable, manual vehicle selection may still be possible.

Failure of AutoVIN to identify a vehicle does not by itself indicate a fault with the scanner.

CAN-FD Support

The MB V3.0 supports CAN-FD, which is used on a growing number of newer Mercedes-Benz electronic systems.

It also supports conventional CAN and other compatible automotive communication protocols.

CAN-FD support means the scanner hardware and software are capable of communicating using CAN-FD where supported.

It does not guarantee unrestricted access to every control module or diagnostic function on every CAN-FD-equipped vehicle.

Standard OBD2 / EOBD Diagnostics

The MB V3.0 also supports all 10 standard OBD2 diagnostic test modes on compatible vehicles.

Functions can include:

• Read emissions-related fault codes

• Clear supported fault codes

• I/M readiness

• Live data

• Freeze-frame information

• Vehicle information

• Oxygen-sensor monitoring

• On-board monitor testing

• EVAP-system testing where supported

• Pending trouble codes

Standard OBD2 / EOBD functions mainly relate to engine and emissions systems and are separate from the MB V3.0's manufacturer-specific full-system diagnostics.

Older Mercedes & Sprinter Vehicles

Certain older Mercedes-Benz and Sprinter vehicles use diagnostic connectors other than the standard 16-pin OBD connection.

iCarsoft offers optional adapters for some of these applications, including:

• Mercedes-Benz 38-pin diagnostic adapter

• Early Sprinter 14-pin diagnostic adapter

These adapters are not necessarily supplied with the standard MB V3.0 package and may need to be purchased separately.

Compatibility with older vehicles should be checked before purchasing any additional adapter.

Live Data

The MB V3.0 can display supported live vehicle data in real time.

This can help diagnose intermittent faults and compare sensor readings while the engine or vehicle system is operating.

Available live-data parameters depend on the vehicle and control module.

Diagnostic History & Reports

The MB V3.0 supports diagnostic history and reporting functions.

Depending on the diagnostic procedure, users may be able to:

• Review previous diagnostic sessions

• Save diagnostic information

• Store diagnostic reports

• Share diagnostic reports

• Print reports using a compatible Windows PC

This can be useful for workshops wishing to maintain records of diagnostic work.

4.0-Inch Colour Display

The MB V3.0 features a 4.0-inch TFT LCD colour display with a resolution of 480 × 320 pixels.

It uses physical navigation buttons rather than a touchscreen, providing straightforward operation in workshop environments.

Vehicle-Powered Operation

During normal vehicle diagnostics, the MB V3.0 receives power through the vehicle's diagnostic connection.

This compact handheld design avoids the need for a large rechargeable tablet battery.

Vehicle & Function Compatibility – Please Read Before Ordering

The MB V3.0 supports a wide range of vehicles, but coverage is not identical across every model and production year.

A vehicle being supported for general diagnostics does not mean it supports every:

• Control module

• Service function

• Active test

• Adaptation

• Teach-in procedure

• Calibration

• Reset or relearn operation

Some vehicles provide extensive functionality, while others provide a smaller selection.

Manufacturer security systems, protected functions or special access requirements may also restrict certain diagnostic procedures.

If you require a particular specialist function, check the latest iCarsoft vehicle and function coverage information before ordering.

Do not assume that a function will work on your particular vehicle solely because it appears in the general MB V3.0 feature list.

Safe Use

The MB V3.0 is a diagnostic and service tool.

Active tests, adaptations, calibrations, teach-in functions and service procedures can command or alter vehicle systems and should only be carried out when the operator understands the procedure and its effect on the vehicle.

Before carrying out active tests or service procedures:

• Position the vehicle safely.

• Apply the parking brake where appropriate.

• Keep people and equipment clear of moving components.

• Maintain suitable vehicle battery voltage where required.

• Follow appropriate vehicle repair and safety procedures.

• Do not interrupt adaptations, calibrations or relearn procedures unless instructed.

A diagnostic trouble code provides information recorded by a vehicle control system. It does not automatically prove that a particular component requires replacement.

Correct fault diagnosis may require additional testing and appropriate technical repair information.

Please Note

Product specifications, software coverage and available functions may change as iCarsoft releases software updates.

Packaging, screen layouts and minor product details may vary according to production batch or manufacturer updates.

The functions available on any individual vehicle are determined by the vehicle itself, its electronic systems, installed equipment and the diagnostic coverage provided by the current iCarsoft software.
