Supported American Vehicle Makes

The US V4.0 is designed specifically for the following vehicle groups:

• Chrysler
• Dodge
• Jeep
• Ford – including US Ford, EU Ford and AU Ford
• GM
• Holden

Exact diagnostic, service, coding and active-test coverage depends on the vehicle model, production year and installed control modules.

Who Is the iCarsoft US V4.0 For?

The US V4.0 is well suited to owners, enthusiasts and independent workshops working with American vehicles who need more than basic OBD2 fault-code reading.

It is a strong choice if you want to diagnose faults across multiple vehicle systems, perform maintenance procedures, run active component tests and access supported ECU coding functions without moving to a subscription-based workshop diagnostic platform.

Full-System Diagnostics

Unlike a basic OBD2 scanner that mainly communicates with the engine control unit, the iCarsoft US V4.0 can access numerous control modules throughout supported vehicles.

Depending on the vehicle, diagnostic access can include:

• Engine
• Automatic transmission
• ABS
• Airbag / SRS
• Electronic parking brake
• Steering systems
• Body control modules
• Climate control
• Instrument cluster
• Battery management
• Lighting and comfort systems
• Other manufacturer-specific control modules

Functions include reading and clearing diagnostic trouble codes, reading ECU information, viewing live data, freeze-frame data, system scanning and accessing manufacturer-specific diagnostic information.

Advanced Bidirectional Control and Active Tests

The US V4.0 supports advanced bidirectional control, allowing the scanner to send commands directly to supported vehicle control modules. This helps test components during troubleshooting instead of relying only on fault codes and live data.

Depending on the vehicle and control module, active tests can include functions such as:

• ABS pump activation
• Window regulator tests
• Fuel pump activation
• Throttle actuation
• Cooling fan activation
• Fuel injector tests
• Door lock operation
• Other supported actuator tests

Exact active-test availability depends on the vehicle and installed control modules.

Ford & Chrysler ECU Coding

One of the key advantages of the US V4.0 is support for ECU coding on compatible Ford and Chrysler-group vehicles.

Supported coding includes selected functions for Ford as well as Chrysler, Jeep and Dodge vehicles. Available coding functions vary by model, production year and control unit, so compatibility should always be confirmed when a specific coding procedure is required.

41 Service and Maintenance Functions

The iCarsoft US V4.0 includes 41 service and maintenance functions for supported vehicles. These cover both common maintenance procedures and more advanced repair and adaptation functions.

Depending on the vehicle, functions can include:

• Oil and service reset
• Electronic parking brake service
• Battery management reset
• DPF regeneration
• Steering angle sensor calibration
• ABS bleeding
• Injector coding
• Electronic throttle adaptation
• TPMS-related functions
• Additional manufacturer-specific reset, adaptation and calibration functions

Exact function availability varies by vehicle.

US V3.0 vs US V4.0

The US V4.0 is the upgraded successor to the US V3.0. Both offer full-system diagnostics and bidirectional control, but the V4.0 adds several important hardware and software improvements.

The biggest V4.0 upgrades are the 5-inch Android touchscreen, Wi-Fi updates and ECU coding support. Vehicle coverage remains broadly aligned with the earlier US-series models. :chatgpt-content-reference{index=”1″}

CAN-FD Support

The iCarsoft US V4.0 supports the newer CAN-FD communication protocol, including support for newer GM and Chrysler vehicles. The manufacturer specifically highlights CAN-FD support on many 2020-and-newer American platforms.

AutoVIN Vehicle Identification

The AutoVIN function can automatically identify supported vehicles through the diagnostic connection, reducing the need to manually enter vehicle information.

Lifetime Free Wi-Fi Updates

Software updates for the US V4.0 are included for the lifetime of the device. Updates are downloaded directly through Wi-Fi, with no annual diagnostic software subscription fees.

Diagnostic History and Reports

The US V4.0 stores diagnostic history so previously tested vehicles and scan results can be accessed again later. Reports can also be saved, shared and printed using a compatible Windows computer connected through USB.

Standard OBD2 / EOBD Functions

In addition to manufacturer-specific diagnostics, the US V4.0 supports all 10 standard OBD2 test modes on compatible vehicles.

• Read fault codes
• Clear fault codes
