22+ active tests and bi-directional control

The US V4.0 can send commands directly to supported modules and actuators. The manufacturer claims 22+ active tests, and their range is expanded with updates.

Examples:

• activating the ABS pump,
• controlling window lifters,
• activating the fuel pump,
• controlling the throttle,
• controlling the EGR valve,
• testing injectors,
• activating radiator fans,
• controlling transmission solenoids.

The availability of a specific test depends on the model, year, and controller version.

Ford ECU coding – selected vehicles 2003–2023

The US V4.0 offers advanced coding and personalization functions for supported Ford vehicles.

The manufacturer indicates, among other things:

• changing tire sizes and calibrating the speedometer,
• configuring axle ratios,
• settings related to tank capacity,
• configuring Hill Start Assist and selected braking functions,
• enabling and disabling selected warnings,
• personalizing sound signals,
• configuring lighting and light delay,
• comfort settings for remote start,
• configuring selected instrument cluster settings.

The range of coding functions depends on the model and year of the vehicle.

Chrysler / Jeep / Dodge ECU coding

In supported Chrysler, Jeep, and Dodge models, the US V4.0 allows access to selected BCM module settings and personalization functions.

The manufacturer lists, among other things:

• FOBIK system settings and safety alerts,
• enabling and disabling visual alerts when locking the vehicle,
• configuring the sound signal / horn when locking,
• controlling the display of selected warning messages on the instrument cluster,
• configuring the logic for hazard lights.

The manufacturer publishes a list of specific models and years, so we recommend confirming compatibility by VIN before selling the device for a specific coding function.

Scope of ECU coding

The current manufacturer page declares ECU coding for some vehicles Ford, Chrysler, Jeep, and Dodge.

The manufacturer notes that coding is not available for all vehicles of these brands and is gradually expanded through software updates.

ECU coding in the US V4.0 is not equivalent to full online programming, J2534 Pass-Thru, or flashing all controllers.

41 service functions – 9 popular + 32 advanced

The US V4.0 offers a total of 41 service functions:

• 9 popular service functions for daily maintenance and servicing,
• 32 advanced functions intended for professional technicians.

The scope includes resets, adaptations, and service procedures depending on the specific vehicle.

Not every one of the 41 functions is available in every car. Availability depends on the brand, model, year, and ECU configuration.

CAN-FD for newer American cars

The US V4.0 supports the modern CAN-FD protocol, which is used in new generations of automotive electronics.

The manufacturer specifically declares CAN-FD support in selected GM and Chrysler models from around 2020.

CAN-FD support increases compatibility with newer cars equipped with higher bandwidth communication networks.

AutoVIN – automatic vehicle identification

The AutoVIN function automatically reads the VIN and identifies the vehicle in supported models, which shortens the time to start diagnostics.

If AutoVIN does not recognize the car, the vehicle can be selected manually. The manufacturer notes that the lack of AutoVIN functionality does not automatically mean a lack of diagnostic support.

Full 10 OBDII / EOBD modes

The US V4.0 supports all 10 standard OBDII diagnostic modes for compatible vehicles from 1996 onwards.

• Read Codes,
• Erase Codes,
• I/M Readiness,
• Live Data,
• Freeze Frame,
• Vehicle Information,

Important information regarding compatibility

The US V4.0 is a device primarily intended for Chrysler, Dodge, Jeep, Ford, GM, and Holden cars. The range of diagnostics, active tests, ECU coding, and service functions depends on the specific model, year, target market, and controller version.

Not every one of the 41 service functions or 22+ active tests is available in every car.

ECU coding is currently declared for some Ford and Chrysler / Jeep / Dodge vehicles and should not be equated with full online programming of all controllers.

The manufacturer specifically declares CAN-FD for selected GM and Chrysler from around 2020.

The current manufacturer page does not declare DoIP or J2534 Pass-Thru for the US V4.0 model.

Before purchasing for a specific vehicle, we recommend checking compatibility by VIN number.
