Designed for Volkswagen Group Vehicles

The VAWS V3.0 is primarily designed for vehicles within the Volkswagen Group.

Supported applications include vehicles from manufacturers such as:

• Volkswagen

• Volkswagen Commercial Vehicles

• Audi

• SEAT

• Skoda

• Bentley

• Lamborghini

• Bugatti

• VW LT3 applications

• MAN light-duty applications

Vehicle coverage varies according to model, production year, electronic architecture and installed control modules.

A manufacturer or vehicle model being supported does not mean every diagnostic, service, coding or active-test function will be available on every vehicle from that manufacturer.

Full-System Diagnostics

A basic OBD2 reader normally concentrates mainly on engine and emissions-related information.

The VAWS V3.0 is designed to communicate with manufacturer-specific electronic control modules throughout supported Volkswagen Group vehicles.

Depending on the individual vehicle, accessible systems may include:

• Engine

• Automatic transmission

• ABS

• Airbag / SRS

• Electronic parking brake

• Steering

• Body control modules

• Instrument cluster

• Climate control

• Battery management

• TPMS

• Suspension

• Lighting

• Convenience systems

• Other supported electronic control modules

Available diagnostic functions can include:

• Reading diagnostic trouble codes

• Clearing diagnostic trouble codes

• Viewing ECU information

• Viewing live sensor data

• Freeze-frame information

• Full vehicle system scans

• Diagnostic history

Important

Not every system is accessible on every vehicle.

System coverage depends on the individual vehicle, its electronic architecture, installed control modules, model year and the diagnostic access permitted by the vehicle manufacturer.

Some newer vehicles may also use security gateways or other access restrictions which can limit certain functions.

Bi-Directional Active Testing

The VAWS V3.0 supports bi-directional or active testing on compatible vehicles.

Active testing allows the scanner to send commands directly to supported vehicle control modules and components rather than simply reading information from them.

This can help technicians confirm whether a component responds correctly when commanded by the diagnostic tool.

Depending on the vehicle, available active tests may include operations involving:

• ABS components

• Window regulators

• Fuel pump

• Wiper and washer systems

• EGR components

• Fuel injectors

• Cooling fans

• Transmission components

• Other supported actuators and outputs

Active tests can be extremely useful for fault-finding, but availability varies significantly between vehicles.

The fact that the VAWS V3.0 supports a particular type of active test does not mean that test is available on every Volkswagen, Audi, SEAT or Skoda.

Important – Service Functions Vary by Vehicle

The VAWS V3.0 does not provide all 41 functions on every vehicle.

The number and type of functions available depend on factors including:

• Vehicle manufacturer

• Model

• Production year

• Engine

• Transmission

• ECU specification

• Factory-installed equipment

• Software version

• Communication protocol

• Security or gateway restrictions

Some supported vehicles may provide a large range of service functions, while others may provide substantially fewer.

For example, the fact that the VAWS V3.0 supports DPF regeneration, injector coding, battery registration or ABS bleeding as platform features does not mean those functions will be available on every supported vehicle.

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

Basic Settings

On supported Volkswagen Group vehicles, the VAWS V3.0 provides access to Basic Settings functions.

These may be used for manufacturer-specific procedures such as:

• Component calibration

• Sensor initialisation

• Relearning procedures

• Resetting learned values

• Component replacement procedures

The exact Basic Settings available depend on the individual vehicle and control module.

Adaptation Functions

The VAWS V3.0 supports Adaptation functions on compatible vehicles.

These may allow supported control modules to relearn or modify certain stored parameters following repairs, replacement components or changes to vehicle configuration.

Adaptation functions vary significantly between vehicles and control modules.

They should only be used when the operator understands the procedure being carried out and the effect of changing the relevant parameter.

ECU Coding

The VAWS V3.0 provides ECU coding capabilities on supported Volkswagen Group applications.

Depending on the vehicle and control module, coding may allow configuration of supported vehicle or ECU parameters following component replacement or changes to vehicle configuration.

Possible applications can include:

• Vehicle configuration parameters

• Body or model configuration

• Steering orientation

• Regional settings

• Control-module installation information

• Lighting preferences

• Central-locking preferences

• Other supported configuration values

Coding capability varies by vehicle and control module.

The presence of ECU coding as a VAWS V3.0 feature should not be interpreted as meaning every control module on every vehicle can be coded.

Security Login

Certain Volkswagen Group control modules require security access before protected functions can be performed.

The VAWS V3.0 supports Security Login functionality on compatible applications.

Availability and required access procedures vary according to vehicle, ECU and software configuration.

CAN-FD Support

The VAWS V3.0 supports CAN-FD, the higher-speed communication protocol used on an increasing number of modern vehicles.

It also supports conventional CAN and earlier supported automotive communication protocols.

CAN-FD support means the hardware and software platform is capable of communicating using the protocol where supported.

It does not guarantee unrestricted diagnostic access to every system on every CAN-FD-equipped vehicle.

AutoVIN Vehicle Identification

On compatible vehicles, the VAWS V3.0 supports AutoVIN vehicle identification.

AutoVIN can automatically identify vehicle information after connection, helping speed up vehicle selection.

AutoVIN availability depends on the vehicle and its communication protocol.

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

Failure of AutoVIN to identify a vehicle does not by itself indicate that the scanner is faulty.

Standard OBD2 / EOBD Diagnostics

In addition to its Volkswagen Group-specific functions, the VAWS V3.0 supports standard OBD2 / EOBD diagnostics on compatible vehicles.

Standard functions can include:

• Read engine and emissions fault codes

• Clear supported fault codes

• Live data

• Freeze-frame data

• I/M readiness

• Vehicle information

• Oxygen-sensor monitoring

• On-board monitoring

• EVAP system tests where supported

• Pending trouble codes

Standard OBD2 / EOBD functions mainly relate to engine and emissions systems.

They should not be confused with the VAWS V3.0's manufacturer-specific full-system Volkswagen Group diagnostic functions.

4.0-Inch Colour Display

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

The scanner uses physical navigation buttons rather than a touchscreen, making it practical for regular workshop use.

Its compact handheld design provides straightforward navigation without the charging requirements associated with larger tablet-style diagnostic systems.

Vehicle-Powered Operation

During normal diagnostic operation, the VAWS V3.0 receives power through the vehicle's diagnostic connection.

Manufacturer specifications state:

Operating voltage: 9–18V
Typical power consumption: approximately 1.8W

Lifetime Free Software Updates

Vehicle and Function Compatibility – Please Read Before Ordering

The VAWS V3.0 covers a wide range of Volkswagen Group vehicles, but coverage is not identical across every model or production year.

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

• Control module

• Service function

• Active test

• Adaptation

• Coding operation

• Security function

Some vehicles may offer extensive functionality, while other supported vehicles provide a smaller selection.

Newer vehicle security systems and gateway restrictions may also affect the functions available.

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

Do not assume that a function is available on your particular vehicle solely because it appears in the VAWS V3.0 general feature list.

Safe Use

The VAWS V3.0 is a diagnostic and service tool and should be operated in accordance with its supplied instructions and appropriate vehicle workshop procedures.

Bi-directional tests, adaptations, coding and service procedures can command, reset or alter vehicle systems.

These functions should only be used 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 manufacturer repair and safety procedures.

• Do not interrupt coding or adaptation procedures unless instructed to do so.

Diagnostic trouble codes are diagnostic information and should not automatically be treated as proof that a particular component requires replacement.

Additional testing and appropriate vehicle repair information may be required to correctly diagnose a fault.

Please Note

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

Images are for illustration purposes. Packaging, screen layouts and minor product details may vary according to production batch or manufacturer updates.

The VAWS V3.0 is supplied as a diagnostic and service tool. The functions available on any individual vehicle are determined by the vehicle itself, its electronic systems and the diagnostic coverage available in the installed iCarsoft software.
