Land Rover Electrical Diagnostics
Land Rover shares JLR's BCM, KVM and gateway architecture with Jaguar, and adds terrain-response and air-suspension control systems. KVM and BCM faults cause the same key-not-detected and no-start issues, while suspension, terrain and chassis modules generate their own warning messages. Diagnosis uses SDD and Pathfinder.
