U0001 on Land Rover
High Speed CAN Communication Bus
U0001 on Land Rover vehicles indicates high speed can communication bus. Au7o has documented this code across 1 Land Rover model — most commonly on Range Rover Sport. This network code indicates a general fault on the high-speed Controller Area Network (CAN) communication bus, the main data backbone that lets vehicle modules talk to each other. The computer detected a problem with bus communication, such as a wiring fault, short, or loss of data integrity on the high-speed bus. Because many critical modules share this bus, faults can cause multiple unrelated warning lights, no-communication conditions, or driveability issues. Diagnosis focuses on bus wiring, connectors, and the modules connected to it.
Common Causes of U0001
- •Damaged, shorted, or open CAN bus wiring
- •Corroded or loose connectors on the bus
- •A failed module dragging down the bus
- •Short to power or ground on CAN high/low lines
- •Faulty bus termination resistor
- •Water intrusion / corrosion in a harness
- •Poor ground or power distribution

- Pivi Pro Infotainment Freezing, Black Screen, and Camera System Dropout2023-2025
Owners of 2023-2025 Range Rover Sport models frequently report the curved Pivi Pro center display freezing, rebooting, going black, or losing audio/navigation/climate control responsiveness. Because many vehicle functions are integrated into the touchscreen, these failures can also disable surround-view cameras, parking graphics, Bluetooth, and HVAC controls until the system reboots. The issue is widely discussed on owner forums and reflected in complaints involving software instability on the new-generation infotainment platform.
