Stop Guessing. Start Fixing: The Ultimate Tool for Japanese & Korean C – iCarsoft Official Store

Reviewing the new iCarsoft JP V4.0 Diagnostic Scanner

If you own a Toyota, Honda, Nissan, Hyundai, or Kia, you likely bought it for one reason: Reliability. These cars are built to last. But even the most reliable engines need maintenance, and modern Asian vehicles are packed with complex electronics that a basic $20 code reader simply cannot access.

Enter the iCarsoft JP V4.0. Designed specifically for Japanese and Korean vehicle makes, this tool bridges the gap between simple DIY scanners and expensive dealership equipment.

1. Specialized Coverage for Asian Imports

Generic scanners often struggle with manufacturer-specific codes. The JP V4.0 comes pre-loaded with software for major Asian brands, ensuring you get a comprehensive scan of all supported systems.

Supported Brands: Toyota, Lexus, Scion, Honda, Acura, Nissan, Infiniti, GTR, Hyundai, Kia, Mazda, Mitsubishi, Subaru, Suzuki, Isuzu, and Daewoo.

2. The Power of "Bi-Directional" Control

Most scanners are passive—they only "listen" to the car. The JP V4.0 is active. It features Bi-directional Control (Actuation Tests).

This means you can send commands to your vehicle to test components instantly. Not sure if your window motor is broken or if it's just a switch? Use the scanner to command the window up and down. You can test door locks, mirrors, wipers, and even adjust the throttle.
