- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- U0064 is the umbrella fault for Vehicle Communication Bus E, the fifth freely assignable network slot. Jaguar Land Rover documents it for the 2022-25 Range Rover (L460) and 2023-25 Range Rover Sport (L461): modules store U0064-88 (bus off) and U0064-87 (missing message), often together with U0080 codes for Bus F, when connector CM32B3/4 between the main body and instrument panel harnesses is not fully latched. Owners report electrical faults around power mode zero and FlexRay module functions, sometimes only intermittent and depending on movement in the cabin or on temperature. JLR has the connector unplugged, its pins inspected and relatched even when it looks secure. Volkswagen Group uses the neighbouring code U0065 for the infotainment CAN in the gateway.
