Lock50 SW39 Supports reset of IPCB (Instrument Panel Cluster B) belonging to the latest generation of Jaguar Land Rover vehicles.

The code R8E2-10F948 -XX is an engineering part number for an IPCB (Instrument Panel Cluster B) belonging to the latest generation of Jaguar Land Rover vehicles.

Specifically, this part is used in the New Range Rover Sport (L461) and the New Range Rover (L460), typically for the 2023–2026 model years.

Engineering Part Number Breakdown

• R8E2: This prefix identifies the specific platform and revision. The "R" series typically denotes parts associated with the newest MLA (Modular Longitudinal Architecture) used in the L460/L461.
• 10F948: This is the base engineering code for a "Full Digital Virtual Instrument Cluster." (In older models, this was 10849; the 10F948 designation is for the high-definition "curved" or bezel-less displays found in the newest models).
• XX: This suffix refers to the specific software/hardware build level (e.g., LHD/RHD, region, or HUD compatibility).

Technical Details for this IPCB

Important Replacement Note

Because this unit is from the EVA 2.0 architecture, it is significantly more restricted than previous versions:

1. Cloud-Only Programming: Unlike the older 2017–2021 clusters that could be programmed with offline versions of Pathfinder, this unit must be programmed using JLR's TOPIx Cloud.
2. Strict Security: These clusters are paired to the vehicle's "Gateway" and Security Module. If you are buying a used unit with this part number, ensure you have a specialist who can "virginize" the EEPROM/Processor, as standard JLR dealer software will block the installation of a used cluster.
3. Lock50 + Sw39 Module support making clusters in virgin state in 1 click via OBD

EVA 2.0 (Electrical Vehicle Architecture 2.0) is the "digital brain" or spine of all modern Jaguar Land Rover vehicles produced from roughly 2020/2021 onwards.

Think of it as the jump from a flip phone to a modern smartphone. While older JLR cars had multiple separate computers that barely talked to each other, EVA 2.0 unifies the car into a high-speed, always-connected network.

1. What makes EVA 2.0 different?

In previous JLR generations (like EVA 1.5 found in the 2017–2019 Range Rover), the car used traditional "CAN-bus" wiring, which is slow and limited. EVA 2.0 features:

• Automotive Ethernet: The car uses high-speed fiber-optic style data transfer. This is why the IPCB (your instrument cluster) can show complex 3D Google Maps and high-res video without lagging.
• SOTA (Software Over-The-Air): Like a Tesla or an iPhone, an EVA 2.0 car can update almost every module (engine, brakes, infotainment) via Wi-Fi or its built-in 4G/5G dual-sims while it's parked in your driveway.
• Pivi Pro Infotainment: EVA 2.0 is the foundation for the Pivi Pro system. It has its own dedicated power source, so the screens turn on instantly when you open the door, rather than waiting for the car to "boot up."

2. Which Models use EVA 2.0?

If your car has the newer Pivi Pro (usually a curved glass screen) rather than the older Touch Pro Duo (dual screens), it is an EVA 2.0 car.

• New Defender (L663): 2020–Current
• New Range Rover (L460): 2022–Current
• New Range Rover Sport (L461): 2023–Current
• Discovery 5 / Discovery Sport: 2021 Facelift onwards
• Jaguar F-Pace / XF / XE: 2021 Facelift onwards
• Range Rover Velar: 2021 Facelift onwards

3. Why does this matter for your Part Number?

Because of EVA 2.0, your part number (R8E2-10F948-LB) is part of a very locked-down ecosystem.

• Cloud-Linkage: In the old days, a mechanic could use a laptop to tell a car "you have a new dashboard." In EVA 2.0, the car must "call home" to JLR's servers in the UK to authorize the part.
• Unmatched Security: The cluster is cryptographically paired to the vehicle's Gateway. If the security keys don't match (which happens if you swap a used part), the car will often enter a "No Start" condition or "Transport Mode" to prevent theft.
