All Terrain Progress Control (ATPC) Retrofit for Jaguar Land Rover
Product Overview
Our ATPC retrofit brings genuine JLR All Terrain Progress Control to your existing vehicle. We install original equipment control switches, body control module updates, and factory wiring. The result matches a vehicle built with the ATPC option from the factory.
You operate the system through the existing centre console switch and the driver information display. The vehicle maintains your chosen set speed between approximately 2 mph and 19 mph. No aftermarket controllers or visible modifications appear anywhere in the cabin.
What the Retrofit Includes
- Genuine JLR ATPC control switch pack
- Factory specification wiring harnesses and connectors
- Body control module and terrain response integration update
- Engine and braking system calibration files
- Vehicle configuration file update
- Full functional testing on varied surfaces
How All Terrain Progress Control Works
ATPC functions like a low-speed off-road cruise control. When you activate the system and set a speed, the vehicle manages the accelerator and brakes automatically. You remain in full control of steering. The system adjusts wheel speed individually to maintain traction on slippery or uneven ground.
The system integrates with Terrain Response and the existing stability control sensors. You select the appropriate terrain mode, and ATPC optimises power delivery and braking intervention for those conditions. The driver information display shows the selected speed and system status clearly. ATPC operates in forward and reverse gears, helping you negotiate descents and tight manoeuvres.
JLR Platform Compatibility
We supply ATPC retrofits for Range Rover, Range Rover Sport, Range Rover Velar, Range Rover Evoque, Discovery, Discovery Sport, and Jaguar F-Pace. Most vehicles from 2016 onward with Terrain Response and compatible control modules qualify. Our team confirms your VIN and current specification before you order.
Installation and Programming
LR-Retrofit technicians complete the installation at our workshop. We fit the ATPC switch pack in the factory position, route the wiring harnesses through the original console conduits, and update the body control module. After installation, we load the engine and braking calibration files and configure the vehicle using JLR diagnostic equipment. We then test the system on different surfaces to verify correct speed control and smooth brake intervention.
