Own an American Car? Here is Your New Best Friend.

Meet the all-new iCarsoft US V4.0 – Professional Diagnostics for Ford, GM, and Chrysler.

If you drive a Chevrolet Silverado, a Ford F-150, or a Jeep Wrangler, you know that American engineering is built tough. But when the electronics start acting up, finding the root cause can be a nightmare.

Generic $50 scanners might tell you that there is a problem, but they rarely tell you where or how to fix it. Enter the iCarsoft US V4.0, our latest powerhouse designed specifically for American vehicle makes.

💡 Quick Summary: The US V4.0 isn't just a code reader. It is a full-system bi-directional scanner with a 5-inch touchscreen, Wi-Fi updates, and over 30 service functions—perfect for the serious DIYer.

1. Beyond the "Check Engine" Light

Most basic tools only look at the engine. But modern cars are computers on wheels. The US V4.0 dives deep into all vehicle systems:

Transmission: Check fluid temps and shift solenoids.
ABS (Braking): Diagnose sensor faults and bleed the brakes.
SRS (Airbag): Read and clear safety system codes.
Body Electronics: Door locks, windows, and seat controls.

2. The "Pro" Feature: Bi-Directional Control

This is the game-changer. Standard scanners are "listeners"—they only read data. The iCarsoft US V4.0 is a "talker."

With Bi-Directional Control (Actuation Tests), you can send commands to your car to test parts instantly.

Suspect a dead fuel pump? Turn it on with the scanner.
Window stuck? Command the motor to roll it up.
Fan not spinning? Force it to run.

This feature alone saves hours of manual troubleshooting.

3. 30+ Maintenance Services (Reset Functions)

Stop paying the dealership for routine resets. The US V4.0 handles over 30 common maintenance tasks:

🛢️ Oil Reset
Reset service intervals instantly after an oil change.

🔋 Battery Registration (BMS)
Tell the ECU you installed a new battery to prevent overcharging.

🛑 EPB Reset
Retract electronic parking brakes safely for pad replacement.

🔄 SAS Calibration

4. Smart Hardware for Modern Mechanics

We ditched the clunky buttons. The US V4.0 features a crisp 5-inch LCD touchscreen that makes navigation as easy as using your phone.

Auto VIN: Automatically identifies your car’s make, model, and year in seconds.
Wi-Fi Updates: No more cables and PCs. Just connect to Wi-Fi and click "Update" to get the latest software.
Data Sharing: Generate, save, and print professional diagnostic reports to share with your mechanic or customers.
