iCarsoft JP v4.0 Japanese/Korean Vehicle Scan Tool

The iCarsoft JP V4.0 is a dedicated full-system diagnostic tool for major Japanese and Korean vehicle makes. It is designed for home mechanics, fleet users, mobile technicians and independent workshops that regularly work on Toyota, Lexus, Honda, Nissan, Hyundai, Kia and other supported Asian vehicles.

Using iCarsoft’s newer V4 platform, it combines a 5-inch Android touchscreen, AutoVIN, manufacturer-specific full-system diagnostics, bi-directional active testing, more than 40 service functions, CAN-FD support, diagnostic reports and lifetime free Wi-Fi updates.

Why Choose the JP V4.0?

The JP V4.0 concentrates its software on 16 Asian marques rather than spreading coverage across the entire global market. It provides access to supported manufacturer-specific systems and maintenance routines that a basic universal OBD2 reader cannot reach.

Key Features

Full-System Diagnostics

The JP V4.0 is designed to communicate with manufacturer-specific control modules throughout supported vehicles. Depending on the model, this can include engine, transmission, ABS, airbags, steering, instrument cluster, body control, climate control, electronic parking brake, suspension, lighting, comfort systems, gateway modules and other fitted electronics.

Available functions include reading and clearing fault codes, viewing ECU information, checking live data and freeze-frame information, carrying out a complete vehicle scan and opening individual modules for more focused diagnosis.

The exact systems available depend on the vehicle’s make, model, year, market specification and fitted control modules.

Bi-Directional Control and Active Testing

Bi-directional control allows the JP V4.0 to send commands to supported modules and components rather than only reading stored information. This can help confirm whether a component responds before replacement parts are ordered.

Depending on the vehicle, active tests can include EVAP components, ABS pumps, windows, mirrors, door locks, sunroofs, fuel pumps, throttle actuators and other supported electrical systems.

Active-test coverage varies by make, model, year and fitted ECU. A test available on one vehicle may not be available on another.

40+ Service and Maintenance Functions

The JP V4.0 combines nine regularly used service procedures with more than 30 higher-level routines for supported vehicles.

Additional supported procedures can include air suspension service, air-conditioning routines, headlamp calibration, engine and transmission adaptations, airbag functions, window and seat calibration, fuel-pump activation, EGR and AdBlue procedures, clutch matching, crankshaft learning, turbocharger functions, radar and camera calibration, vehicle personalisation and other vehicle-specific operations.

Service-function availability varies by make, model, year, system and ECU configuration. A listed function is not available on every supported vehicle.

CAN-FD and Later-Model Vehicles

The JP V4.0 supports CAN-FD communication used by selected newer vehicles. This improves access to compatible later-model platforms that may not communicate fully with older diagnostic hardware.

Some modern vehicles also use manufacturer security gateways that can restrict active tests or service procedures. Exact access depends on the vehicle and manufacturer requirements.

Touchscreen Hardware and Updates

The Android platform uses a quad-core 1.3GHz processor, 32GB internal storage and a 5-inch 854 × 480 capacitive touchscreen. The 5000mAh rechargeable battery provides around six hours of continuous use.

Updates are downloaded directly through 2.4GHz Wi-Fi. No annual update subscription is required.
