Range Rover Electrical Diagnostics
Range Rover uses the full JLR electronics stack — BCM, KVM, gateway — with the most advanced chassis, suspension and driver-assistance systems in the group. That means more modules, more software and more network traffic, so a single power-supply or communication fault can produce many simultaneous warnings. KVM, BCM, suspension and ADAS faults are all common.
