PICK ANY 2 · FREE OF CHARGEIt doesn’t just read codes — it commands your car.
The LR V4.0 doesn't just read codes—it talks directly to your car. This professional-grade scanner sends active commands straight to individual vehicle modules and watches them respond in real time, bypassing the cabin switches entirely.
Body & Comfort Active Tests
Imagine a power window won't roll up. Is it a broken door switch, a blown fuse, or a dead motor? Instead of ripping apart the door panel to test wires, you just tap the screen on your LR V4.0. If the window rolls down, you know the motor is perfectly fine and the switch is the culprit. No more guesswork, no more buying parts you don't need.
- Command Window Regulators: Drive windows up and down straight from the scanner to isolate bad switch clusters in seconds.
- Trigger Door Locks & Side Mirrors: Actuate locks and mirrors on demand to pinpoint body control module glitches.
Powertrain & Fuel Active Tests
Send commands straight to the engine-side modules and watch each component respond in real time — no cabin switches, no waiting for the fault to reappear.
- Kick On the Fuel Pump: Activate the fuel pump instantly to verify fuel pressure dropping issues.
- Modulate Throttle Opening: Sweep the throttle to check for sticking carbon deposits.
Chassis & Brake Active Tests
Take direct control of the hydraulic hardware that normally only responds while driving — essential for a proper brake service.
- Cycle the ABS Pump Motor: Run the pump on command to purge trapped air during brake bleeding.
Dynamic Output Tests
Beyond the headline tests, the LR V4.0 can exercise nearly every electrically driven component on the car.
- Any Actuator or Solenoid: Run dynamic output tests on virtually any onboard actuator or solenoid in minutes.
- Confirm Before You Buy: Watch the module respond live and confirm the failed part before ordering a replacement.
A 5-inch Android tablet built to run all day in the bay.
iCarsoft LR V4.0 car diagnostic tool is equipped with a 5-inch HD Touch Screen, Android operating system, Quad Core 1.3 GHz processor, 32GB memory 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 — no subscription, ever.
Unlike other OBD scan tools on the market that require annual subscription fees, the LR V4.0 offers lifetime free software upgrades. Updates are delivered wirelessly via Wi-Fi, with new diagnostic protocols and vehicle model coverage continuously released.
UPDATE PLANReady for the newest Jaguar & Land Rover communication standard.
CAN-FD (Controller Area Network – Flexible Data-rate) is a next-generation automotive communication protocol adopted by Jaguar / Land Rover.
What is CAN-FD?
CAN-FD (Controller Area Network – Flexible Data-rate) is the next-generation evolution of the classic CAN bus, now adopted across the newest Jaguar / Land Rover platforms.
- Flexible Data-Rate: Transfers larger data frames at faster speeds than classic CAN, keeping up with modern vehicle electronics.
- The New Factory Standard: Adopted by Jaguar / Land Rover on the latest platforms.
CAN-FD Ready, Out of the Box
- Native CAN-FD Support: Talks the CAN-FD protocol directly from the standard OBD2 port.
- Newest Models Covered: Keeps the LR V4.0 connected to the latest Jaguar / Land Rover chassis in its coverage range.
One Tool, Every Protocol
CAN-FD is only the newest layer — the LR V4.0 speaks the full range of protocols used across decades of Jaguar / Land Rover models.
- Beyond CAN-FD: Also supports classic CAN, K/L-Line and the other factory protocols listed in the full specifications below.
- Old or New, One Tool: From early CAN models to today's CAN-FD platforms, the LR V4.0 selects the right protocol for the car.
Plug in. Your Jaguar or Land Rover names itself in seconds.
Skip the manual VIN typing — simply plug in, and the tool identifies your vehicle in seconds. No typos, no extra lookup time. This boosts accuracy, eliminates input errors, and delivers a smoother, more reliable diagnostic experience.
One-Plug Identification
- Automatic VIN Read: Simply plug into the OBD2 port and the LR V4.0 identifies your vehicle in seconds.
- No Extra Lookup Time: Skip manual VIN typing and model-menu digging entirely — go straight to diagnostics.
Accuracy Built In
- Eliminates Input Errors: No typos means the scanner always loads the exact software profile for your vehicle.
- Smoother, More Reliable Sessions: Correct identification from the first second delivers a more reliable diagnostic experience.
Manual Selection Backup
AutoVIN depends on individual vehicle ECU protocols. If AutoVIN skips your car, it doesn't mean the device is faulty — you always have a second way in.
- Manual Selection Mode: Pick your model from the menu and every diagnostic and service function works exactly the same.
- Growing VIN Database: Send your VIN to the support team and it will be verified and added in the next software update.
Diagnose in your language, wherever you wrench.
Jaguar / Land Rover scanner LR V4.0 supports English, German, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish, and Finnish.
