All Terrain Progress Control (ATPC) – JLR Off-Road Cruise Control Retrofit
All Terrain Progress Control (ATPC) is a specialised JLR off-road assistance system that functions as low-speed cruise control for challenging terrain[reference:0]. LR-Retrofit activates this factory-hidden feature through pure software enablement, giving your Jaguar or Land Rover vehicle precise speed management across mud, wet grass, ice, snow, and dirt surfaces. You gain full control on steep descents, slippery ascents, and rutted tracks without constant pedal adjustments.
What Does ATPC Do?
ATPC operates between 2 km/h and 30 km/h, allowing you to set a target speed while the system manages throttle and braking automatically. Unlike conventional cruise control, ATPC works in both forward and reverse directions at very low speeds, handling pull-away from standstill, incline ascents and descents, and unstable surfaces such as ice, snow, grass, gravel, sand, and mud.
The system integrates directly with your vehicle’s Terrain Response and traction control modules[reference:4]. Once activated, ATPC modulates individual wheel braking and engine torque to prevent wheel spin and maintain traction. You steer while the vehicle manages power delivery—perfect for technical off-road manoeuvres that demand precision.
Key Technical Features
- Speed Range: Adjustable from 2 km/h to 30 km/h via cruise control buttons on the steering wheel
- Directional Operation: Functions in both forward and reverse at low speeds
- Terrain Integration: Works in direct partnership with Terrain Response and traction control systems
- Surface Coverage: Effective on wet grass, snow, ice, mud, gravel, sand, and dirt roads
- Driver Interface: Factory rotary controller and touchscreen integration with no aftermarket hardware visible
- System Integration: JLR CAN bus, ABS, EPB, transfer case, and locking differentials
- Activation: Pure software-only CCF parameter enablement—no hardware replacements or wiring modifications required
How ATPC Transforms Your Off-Road Experience
ATPC reduces driver fatigue on long off-road journeys by maintaining steady progress without constant manual control. On steep descents, the system syncs with Hill Descent Control to stabilise downhill movement. On slippery ascents, ATPC automatically distributes power evenly across all wheels to minimise slipping, digging, and surface damage.
The result is less stress, greater safety, and more confidence in difficult conditions. You focus entirely on steering and line selection while the vehicle handles the throttle and brake modulation. ATPC creates no DTC faults, preserves all existing ADAS functions, and maintains full MOT and warranty compliance.
Vehicle Compatibility
This ATPC upgrade supports all hardware-equipped modern JLR vehicles. Compatible models include the Defender, Discovery, Discovery Sport, Range Rover Evoque, Velar, Range Rover Sport, and Jaguar off-road capable SUVs. Every activation includes pre-service system diagnostics, precise parameter enabling, and post-calibration terrain function testing.
Because ATPC is a factory-hidden feature, no hardware replacements or wiring modifications are necessary. The calibration process is completely reversible and adheres to strict JLR OEM technical standards. Your upgrade persists through battery resets, system scans, and official JLR firmware updates.
