iCarsoft JP V4.0 for Japanese and Korean Vehicle Makes
Engineered for Asian steel. Every marque.
The JP V4.0 is built around the electronic architectures of Asia's great marques — from the bulletproof daily driver to the JDM icon. One tool, the whole grid.
A 5-inch flagship, built to work.
iCarsoft JP V4.0 car diagnostic tool is equipped with a 5-inch color touchscreen, Android operating system, Quad Core 1.3 GHz processor, 64GB storage and a 5000mAh battery for around 6 hours of continuous use. It offers a user-friendly interface and an ultra-smooth diagnostic experience.
Pay once. Upgrade forever.
Unlike other OBD scan tools on the market that require annual subscription fees, the JP V4.0 offers lifetime free software upgrades. Updates are delivered wirelessly via Wi-Fi, with new diagnostic protocols and vehicle model coverage continuously released.
Ready for the protocols of tomorrow's Asian cars.
CAN-FD (Controller Area Network – Flexible Data-rate) is a next-generation protocol increasingly used in newer Asian vehicles, allowing much faster data transfer than classic CAN. The JP V4.0 also supports DoIP (Diagnostics over Internet Protocol) for high-speed communication with the newest ECUs.
CAN-FD
A next-generation protocol increasingly used in newer Asian vehicles. The JP V4.0 speaks it natively — so the newest ECUs aren't a dead end.
It doesn't just read. It commands.
Unlike ordinary OBD scanners that only read fault codes, the JP V4.0 lets you command individual components directly — Head Lamp Service, Run window regulators, Door-Window-Roof, and Injector Coding and Door Service. Identify the faulty part in minutes, without trial-and-error.
Head Lamp Service
Initializes the adaptive headlamp system.
