Complete Land Rover Module Bench Services & Board-Level Diagnostics
RFA / KVM Keyless Module (Secured SPC560B60L3 MCU)
What This Module Does
The Remote Function Actuator (RFA/KVM) governs keyless entry, proximity key detection, start authorisation, and ultra-wideband anti-theft protocols across Range Rover and Land Rover platforms.
How Main Dealers Fail You
During key programming or low battery events, the secured SPC560B60L3 MCU corrupts or locks up. Main dealers force total replacement of the RFA module, BCM, and all vehicle smart keys at thousands of pounds.
Our Advanced Bench Solution
We unlock and reprogram the secured SPC560B60L3 MCU directly on the bench. We recover damaged D-Flash/EEPROM security dumps and perform 1:1 bench cloning onto donor RFA units without touching the vehicle's original coding structure.
ATCM (All-Terrain Response Control Module)
What This Module Does
The Terrain Response Controller (ATCM) manages dynamic driving modes (Grass, Gravel, Snow, Mud, Sand, Rock Crawl), air suspension dynamic valving, and electronic centre differential lock commands.
How Main Dealers Fail You
Water spillages on the centre console or internal CAN-Bus driver failures trigger dynamic suspension and terrain system lockouts. Dealers require full console disassembly and costly module replacements.
Our Advanced Bench Solution
We perform trace-level repairs, power-management IC replacements, and MCU re-flashing on Land Rover ATCM Terrain Response Modules. We restore CAN-Bus communication and functional mode switching directly on the bench.
Range Rover Evoque EPB (Electronic Parking Brake) Module
What This Module Does
The EPB Control Unit controls rear brake calliper actuator motors, dynamic emergency braking functions, and automatic incline hill-hold features for Evoque (2013+) and Discovery Sport models.
How Main Dealers Fail You
High-current actuator shorts or moisture exposure in rear quarter panels destroy the internal driver MOSFETs. Dealers push for complete braking wiring harness and computer overhauls.
Our Advanced Bench Solution
We repair thermal MOSFET drivers and high-current traces on Evoque 2013+ EPB Modules. We extract data from damaged EEPROMs and clone parameters to replacement units for instant plug-and-play installation.
Range Rover Seat Control Modules (DG256 MCU)
What This Module Does
The Seat Computer manages multi-way power seat adjustment motors, memory positioning settings, massage features, and heating/cooling airflow drivers for 2014+ Range Rover Vogue and Sport models.
How Main Dealers Fail You
Under-seat harness tension or liquid damage corrupts the onboard Motorola/NXP DG256 processor. Main dealers insist on replacing complete seat runner frames and harness assemblies.
Our Advanced Bench Solution
We connect directly to the DG256 microcontroller on 2014+ Range Rover Seat Modules. We repair burned circuit traces, clear internal fault dumps, and re-flash MCU operating code on the bench.
Technical Frequently Asked Questions
How does your mail-in postal module repair service work?
You can carefully remove your faulty Land Rover or Range Rover module (RFA/KVM, ATCM, EPB, or Seat Controller) and post it to our Hayes workshop. We test, micro-solder, clone, and repair the unit on our specialised bench setups using Autel IM608 Pro and Xhorse Multi-Prog, returning it plug-and-play.
Why repair or clone a module instead of buying a new one from Land Rover?
Main dealer modules require expensive online TOPIx diagnostic SCN coding and frequently suffer from back-order delays. Bench cloning transfers your original vehicle security and configuration data onto a donor module, saving up to 70% in cost while making the unit immediately operational upon plug-in.
