SW254 ATPC (All Terrain Progress Control)

ATPC (All Terrain Progress Control) enable for Land Rover — switch on low-speed off-road cruise control and its related functions (Hill Descent Control, Low-Speed Progress Control). Set via the CCF and coded to your VIN / As-Built over OBD, remote & mobile. Requires the supporting chassis hardware.

What this activation does

• Enables ATPC — an off-road cruise control that holds a low set speed over rough terrain so you can steer while the car manages throttle and braking.
• Choose the combination that matches your hardware — Hill Descent Control (HDC) only, Low-Speed Progress Control (LSPC) only, or both.
• Software enable via the CCF — the supporting brake/chassis hardware must be present. Coded to your VIN / As-Built.

Key terms explained

• ATPC (All Terrain Progress Control): A low-speed off-road cruise control that keeps the car moving steadily over difficult ground so the driver can concentrate on steering.
• Hill Descent Control (HDC): Automatically controls braking on steep descents to hold a slow, safe speed.
• Low-Speed Progress Control (LSPC): Maintains a chosen crawl speed on- or off-road, similar to a very low-speed cruise control.
• CCF (Car Configuration File): The master list of feature flags stored in the vehicle. Setting a value here switches a factory feature on or off. All of these activations are done by editing the CCF, not by fitting parts.
• As-Built: Your vehicle's original factory configuration record, tied to the VIN. Every change is written back against your As-Built so the car stays consistent with JLR records.
• Coded to your VIN: The change is applied to your specific vehicle over the OBD diagnostic port — remote and mobile, no bench work and no new hardware.
• Error / Undefined: Factory enumeration place-holders that exist inside the parameter list. They are not real choices — do not select them. Pick the plain-English option that matches your vehicle.
