GODIAG SF420 Jaguar Land Rover KVM RFA 2-in-1 Communication Test Cable
The GODIAG SF420 is a 2-in-1 communication test cable designed for bench testing supported Jaguar and Land Rover KVM/RFA modules.
It connects a removed KVM/RFA module to compatible diagnostic equipment, allowing communication to be checked before the module is reinstalled in the vehicle. This is particularly useful after key-matching, MCU replacement or module repair procedures where the module may have lost communication.
The cable includes separate connections for earlier and later KVM/RFA module types, eliminating the need for separate test cables.
Product Features
- Bench communication testing for supported Jaguar and Land Rover KVM/RFA modules
- Two module connections incorporated into one cable
- Supports earlier pre-2017 KVM/RFA modules
- Supports selected 2018–2025 KVM/RFA modules
- Checks module communication before vehicle installation
