OEM-grade Terrain Response 2 AUTO + ATPC retrofit for Land Rover. Adds automatic terrain mode and All-Terrain Progress Control with plug-and-play installation.
Product Overview
LR Retrofit introduces the Terrain Response 2 AUTO + ATPC upgrade for Land Rover vehicles. This retrofit adds the advanced automatic terrain detection system and All-Terrain Progress Control to your existing vehicle. You gain the ability to let the vehicle choose the optimal terrain setting without manual input. The system then maintains a steady low speed over challenging surfaces, freeing you to focus on steering.
The upgrade uses the original JLR control modules and software. You receive the exact hardware and coding required for your specific model. The system integrates fully with the factory touchscreen and instrument cluster. No aftermarket controllers remain visible.
Key Features
- Automatic terrain detection with Terrain Response 2 AUTO mode
- All-Terrain Progress Control (ATPC) for off-road cruise control
- Works with existing Terrain Response rotary controller
- Adjustable speed setting from 2 km/h to 30 km/h
- Full integration with factory electronic differentials
- Low-speed manoeuvring assistance on steep descents
- Plug-and-play with OEM wiring and coding
- No permanent modifications to the vehicle
You select AUTO mode and the vehicle monitors wheel slip, steering angle, and suspension movement. The system then adjusts throttle response, gearbox calibration, and differential locking. You enjoy confident progress on mud, sand, gravel, and rock.
Performance Benefits
Terrain Response 2 AUTO removes the guesswork from off-road driving. You no longer need to manually select Grass/Gravel/Snow or Mud/Ruts. The system reacts instantly to changing surfaces. ATPC then maintains your chosen speed without pedal input. You navigate steep descents and climbs with steady, controlled movement. The result is less driver fatigue and greater safety in difficult conditions.

Vehicles must have the standard Terrain Response system or the required wiring. LR Retrofit confirms exact compatibility from your VIN before dispatch. Models without the rotary controller require an additional switch pack, which we include in the kit.
Installation and Coding Support
We recommend professional installation. LR Retrofit supplies the complete hardware kit with control module, switch pack, and wiring looms. Our technical team provides remote coding support through JLR diagnostic tools. You update the Car Configuration File to activate Terrain Response 2 and ATPC. The software update applies the correct calibration for your model and engine.
The installation process follows the factory method. You replace the existing control module with the Terrain Response 2 unit. The switch pack mounts in the original location. The wiring loom connects to the factory CAN bus. No cutting or splicing of the vehicle harness is necessary.
Technical Note
Terrain Response 2 uses the vehicle’s ABS sensors, steering angle sensor, and electronic differentials. The system evaluates wheel slip and yaw rate continuously. ATPC modulates brake pressure and engine torque to maintain the set speed. You can adjust the speed using the cruise control buttons on the steering wheel. The system disengages when you press the brake pedal firmly.
