Who Is the iCarsoft LR V4.0 For?
The LR V4.0 is well suited to Land Rover and Jaguar owners, enthusiasts and independent workshops that need more than basic fault-code reading.
It is a strong choice if you want to diagnose faults across multiple vehicle systems, perform maintenance procedures, run active component tests and access advanced brand-specific diagnostic functions without moving to a subscription-based workshop platform.
Full-System Land Rover & Jaguar Diagnostics
Unlike a basic OBD2 scanner that mainly communicates with the engine control unit, the iCarsoft LR V4.0 can access numerous control modules throughout supported Land Rover and Jaguar vehicles.
Depending on the vehicle, diagnostic access can include:
- Engine
- Automatic transmission
- ABS
- Airbag / SRS
- Electronic parking brake
- Steering systems
- Body control modules
- Climate control
- Instrument cluster
- Battery management
- Lighting and comfort systems
- Other manufacturer-specific control modules
Functions include reading and clearing diagnostic trouble codes, viewing live data, system scanning, AutoVIN vehicle identification and access to manufacturer-specific diagnostic information.
Full Bidirectional Control and Active Tests
The LR V4.0 supports full bidirectional diagnostics, allowing the scanner to send commands directly to supported vehicle control modules. This helps test components during troubleshooting instead of relying only on fault codes and live data.
Depending on the vehicle and control module, active tests can include functions such as:
- ABS pump activation
- Door lock operation
- Fuel pump activation
- Wiper and washer motor tests
- EGR valve actuation
- Fuel injector tests
- Cooling fan activation
- Transmission solenoid tests
- Other supported actuators
The manufacturer lists more than 18 active-test categories, although exact availability depends on the vehicle and installed control modules.
38 Service and Maintenance Functions
The iCarsoft LR V4.0 includes 38 service and maintenance functions for supported vehicles. These consist of commonly used maintenance functions plus advanced professional procedures. Exact availability depends on the vehicle.
Common Service Functions
- Oil / service reset
- Electronic throttle control
- Electronic parking brake / brake pad reset
- Steering angle sensor calibration
- DPF regeneration
- Injector coding
- ABS bleeding
- Engine control service
- Transmission control service
Advanced Functions
Depending on the vehicle, the LR V4.0 can also support advanced functions such as:
- Seat calibration
- Airbag reset
- Immobilizer service
- Door / window / roof relearning
- Engine idle service
- Odometer value verification
- Turbocharger learning
- Yaw-rate sensor calibration
- Powertrain adaptation reset
- HVAC and stepper motor initialization
Advanced function availability varies by vehicle model, year and control unit.
LR V3.0 vs LR V4.0
The LR V4.0 is the successor to the LR V3.0. Both provide advanced Land Rover and Jaguar diagnostics, but the V4.0 introduces major hardware and usability improvements.
| Feature | LR V3.0 | LR V4.0 |
|---|---|---|
| Land Rover & Jaguar diagnostics | Yes | Yes |
| Full-system diagnostics | Yes | Yes |
| Bidirectional / Active Tests | Yes | Yes |
| Display | 4-inch | 5-inch touchscreen |
| Operating system | Traditional interface | Android |
| Software updates | USB | Wi-Fi |
| Additional vehicle groups | No | 2 included free |
| CAN-FD | Supported | Supported |
| Lifetime free updates | Yes | Yes |
For users comparing the two versions, the biggest V4.0 improvements are the 5-inch touchscreen, Android platform, Wi-Fi updating and two additional vehicle make groups.
Land Rover & Jaguar Coverage
The LR V4.0 comes pre-installed with dedicated diagnostic software for Land Rover and Jaguar vehicles. The manufacturer states support for compatible models from approximately 1996 to 2025, including the Range Rover family. Exact system and function coverage varies by vehicle.
Two Additional Vehicle Make Groups Included
In addition to the pre-installed Jaguar / Land Rover software, the LR V4.0 allows you to download two additional supported vehicle make groups free of charge.
This gives the device three vehicle groups in total without additional diagnostic software subscription fees.
CAN-FD Support
The iCarsoft LR V4.0 supports the newer CAN-FD communication protocol used by newer Land Rover and Jaguar vehicle platforms.
It also supports traditional automotive communication protocols for older vehicles.
AutoVIN Vehicle Identification
The AutoVIN function can automatically identify supported vehicles through the diagnostic connection, reducing the need to manually enter vehicle information.
If AutoVIN does not identify a particular vehicle, manual vehicle selection can still be used.
Lifetime Free Wi-Fi Updates
Software updates for the LR V4.0 are included for the lifetime of the device. Updates are downloaded directly through Wi-Fi, with no annual diagnostic software subscription fees.
5-Inch Android Touchscreen
The LR V4.0 uses a modern Android-based interface with a 5-inch capacitive touchscreen.
