Professional-grade fault-code analysis, live data streaming, and actuator testing across every Jaguar and Land Rover control module using genuine JLR DOIP VCI and UDS protocol.
Our diagnostic service covers every control module in Jaguar and Land Rover vehicles, from engine and transmission to infotainment and body electronics, using dealership-grade tools and protocols.
Read and clear diagnostic trouble codes across all modules: ECM, TCM, ABS, SRS, BCM, KVM, CJB, RFA, IMC, NGI, and more. We interpret manufacturer-specific codes and provide actionable repair guidance.
Real-time parameter streaming from all ECUs. Monitor sensor values, actuator positions, system voltages, and calculated data in real time with engineering-grade precision.
Command individual actuators, solenoids, relays, and motors to verify component operation. Test injectors, fuel pumps, cooling fans, HVAC blend doors, and lighting circuits.
Full UDS diagnostic session support including extended sessions, security access, read/write data by identifier, routine control, and request download for all supported modules.
CAN bus architecture integrity testing, gateway analysis, bus-off detection, and module availability scanning. Diagnose communication faults between modules on high-speed and low-speed CAN networks.
Reset service intervals, oil life, brake pad wear, and inspection reminders. Perform adaptive learning resets for transmission, steering angle, and throttle body calibration.
We diagnose vehicles across all Jaguar Land Rover electrical architectures, from legacy CAN-based systems to the latest DOIP-enabled platforms.
Legacy Jaguar Land Rover electrical architecture using standard CAN and CAN-LIN networks. Full diagnostic coverage via SDD (IDS) with JLR DOIP VCI backward-compatible mode. Covers all XF, XJ, XK, Discovery 3/4, Range Rover L322, and Freelander 2.
Modern JLR architecture with DOIP (Diagnostic Over IP) on high-speed Ethernet backbone. Supports Pathfinder diagnostics, full module programming, and security access. Covers Velar, I-PACE, E-PACE, F-PACE, Discovery 5, Range Rover L405, and Range Rover Sport L494.
Latest generation architecture with enhanced CAN FD and DOIP networks. Supports newest model-year vehicles with updated gateway modules and expanded diagnostic datasets. Full Pathfinder 2023+ coverage with genuine VCI firmware.
Our diagnostic service covers the complete JLR vehicle lineup from 2005 to current model year.
