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.
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.
Diagnose in your language, wherever you wrench.
Far more than a basic code reader.
The LR V4.0 is far more than a basic code reader. It integrates 9 commonly-used service functions for daily maintenance and 29 advanced professional functions for complex repair tasks.
Allows you to reset the engine oil life system, service lamp, service mileage, and service intervals after an oil change.

Relearns the injector control parameters when an injector is renewed or replaced.
Bleeds air from the system to restore ABS brake response, or performs a relearn procedure after ABS replacement.
Supports calibration, height adjustment, system reset, and fault code clearing for air suspension systems. Lets you precisely set ride height, perform system initialization, and resolve common air suspension faults.
Evaluates the battery charge state, monitors closed-circuit current, registers battery replacement, and activates the vehicle's sleep mode.
Allows you to look up the tire sensor IDs from the vehicle's ECU, inputting TPMS sensor replacement IDs and testing sensors.
Supports routine maintenance of A/C modules, including A/C system adaptation reset, compressor reset, compressor break-in, and stepper motor initialization.
Initializes the adaptive headlamp system.
Supports routine maintenance of DSC modules, including resetting or deleting adaptation values, and initializing the unit.
Supports routine maintenance of engine modules, including resetting or deleting adaptation values, and calculating fuel consumption.
Supports routine maintenance of transmission modules, including resetting adaptation values and transmission fluid level adaptation.
Performs calibration after repairing or replacing the seat position drive motor.
Resets airbag data to clear the airbag (SRS) warning light after a collision.
Anti-theft Matching, disable any lost keys and add new keys. ONLY for vehicles with basic Immobilizer system.
Learns the top position of the door window glass, enabling pinch protection and the one-touch-up function.
Adjusts the engine idle speed.
Reads and verifies odometer values stored across multiple ECUs. (Note: this function does not alter mileage; it is intended for lawful service and verification only.)
Performs turbocharger learning after component replacement, or resets stored learned values.
Recirculates a portion of engine exhaust gas back into the intake system.
Performs full calibration after window lift motor repair or replacement.
Resets the AdBlue (urea) level counter after the diesel exhaust fluid is refilled or replaced.

Used for learning and calibration of heads-up display.
Supports EV/hybrid high-voltage battery maintenance, including replacement adaptation and status monitoring.
Changes the vehicle's system language.
Calibrates the rain sensor after windshield replacement or sensor renewal.
Performs radar and camera learning and calibration (ADAS).
Tests each engine cylinder individually by disabling its fuel supply — useful for diagnosing cylinder-specific issues such as misfires or low compression.
Sets or removes the vehicle's maximum speed limit.
Supports oxygen sensor replacement adaptation and initializes the three-way catalytic converter learned values.
Performs seatbelt pretensioner reset and related maintenance after airbag deployment.
Checks and compares odometer data stored across multiple ECUs to detect mileage tampering.
Reads and matches the VIN across all vehicle ECUs to detect inconsistencies or unauthorized module replacement.
Additional service functions are available in the Miscellaneous section.
Reach every ECU — not just the four standard systems.
In addition to the four standard systems (Engine, ABS, Airbags, and Transmission), the LR V4.0 provides diagnostic coverage for more complex vehicle systems.
Dealer-grade adaptations, right in your hands.
Calibrates the yaw rate sensor to OE standards after replacement or alignment — equivalent to the dealer SDD procedure.
Wipes learned shift patterns to reset ECM/TCM adaptive, instantly curing harsh shifts and restoring factory-smooth drivability.
Forces the PCM to relearn precise physical endpoints for throttles and blend doors, fixing erratic idles and ghost climate-control issues.
Re-indexes all cabin blend-door actuators and temperature flaps simultaneously with a single tap, slashing hours off tedious dashboard overhauls.
Overrides and clears protective climate-control codes triggered by low voltage or low freon, unlocking the A/C clutch without a trip to the dealer.
Every emission check, all ten modes, ready to pass.
Supports all 10 OBD2 test modes for vehicles compliant with 1996+ OBDII/EOBD/JOBD/KOBD/CAN/CAN-FD standards: Read Codes, Erase Codes, I/M Readiness, Live Data, Freeze Frame, Vehicle Information, O2 Monitor Test, On-Board Monitor, and EVAP System Test.
