Icarsoft OBD II LR V4.0 Compatible with: Jaguar, Land Rover

The Icarsoft LR V4.0 is a professional vehicle diagnostic tool for Jaguar and Land Rover vehicles. It was developed for ambitious private users, car enthusiasts, independent specialized companies and professional workshops.
It provides manufacturer-level diagnostic capabilities and covers almost all supported control units and vehicle systems, from the engine and transmission, to ABS and SRS airbag, to advanced adjustment and calibration functions. In addition, extensive bi-directional control, 38 service functions and life-long free software updates are available.
The LR V4.0 comes with pre-installed diagnostic software for Jaguar and Land Rover and is ready for immediate use. In addition, two further groups of vehicle brands can be selected and downloaded free of charge.
According to the manufacturer, the unit is compatible with Jaguar and Land Rover models from 1996 to 2025. Thanks to powerful hardware, a large 5-inch/12.7-cm touch screen, CAN-FD support and intuitive operation, the LR V4.0 is suitable for regular maintenance work as well as for demanding diagnostics and repair tasks.

Powerful hardware
The LR V4.0 is equipped with a 5 inch/12.7 cm HD touch screen, Android operating system, quad-core processor with 1.3 GHz, 64 GB memory and a 5,000 mAh battery. The battery life in test mode is approx. six hours. The clear user interface enables a fast and smooth vehicle diagnosis.

Lifetime free online updates
Unlike many other diagnostic tools, the LR V4.0 does not incur annual subscription fees. Software updates are provided free of charge over WLAN for life. New diagnostic protocols, additional vehicle covers and functional improvements are being continuously added.

Support for the current CAN FD protocol
CAN-FD (Controller Area Network – Flexible Data Rate) is a modern vehicle communication protocol used on current Jaguar and Land Rover platforms. The LR V4.0 supports this protocol and thus enables communication with appropriately equipped vehicles and control units.

Advanced bi-directional control
The LR V4.0 not only reads error codes, but also supports active tests and the bi-directional control of many available control units. The diagnostic tool sends specific commands directly to individual components and evaluates their response in real time. This allows faults in switches, wiring, control devices or components to be reduced more quickly, without the need to replace components on suspicion.
Examples of supported active tests on compatible vehicles:
Drive the ABS pump motor and support the brake system bleeding
Raise and lower the power window to test switches, wiring and actuators
Activate the fuel pump and check the function or pressure build-up
Operate the throttle valve opening and check for stiffness or debris
Operate door locks and exterior mirrors to limit faults in the body control system
Perform output and actuator tests on numerous other actuators, solenoid valves and vehicle modules

Automatic vehicle identification using AutoVIN technology
After connection, the LR V4.0 can automatically detect supported vehicles using the vehicle identification number. Manual input is omitted, input errors are reduced and diagnostics can be started faster and more reliably.

Multi-language user interface
Supported languages: German, English, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish and Finnish.

Full OBD2 test modes
The device supports all 10 OBD2 test modes for vehicles with OBDII/EOBD-/OBD-/OBD-/KOBD-/CAN-/CAN-FD standards starting from the year of manufacture 1996, including read and delete error codes, I/M readiness, live data, freeze frame data, vehicle information, O2-sensor test, on-board monitoring, EVAP-system test as well as the reading of pending error codes.

Save and print diagnostic reports
Already tested vehicle systems can be quickly accessed and diagnostic reports can be saved, shared and printed. The feedback function can be used to report problems to technical support during use. Diagnostic reports can be printed for later documentation via a Windows PC and a USB connection.

Supported vehicle protocols
ISO 9141-2, ISO 14230-2, ISO 15765, K/L-Line, flashing code, SAE J1850 VPW, SAE J1850 PWM, ISO 11898 (High Speed, MiddleSpeed, Low Speed and Single Wire CAN), CAN-FD, SAE J2610, GM UART, UART Echo Byte Protocol, Honda Diag-H Protocol, TP2.0 and TP1.6.
