All Terrain Progress Control

What Is the All Terrain Control Module?

The ATCM processes inputs from wheel-speed sensors, steering angle, and ride-height data. Furthermore, it coordinates with the ABS modulator and the transfer case control unit. In short, this module decides which terrain response mode best suits current conditions.

Range Rover All Terrain Control Module Location

On most L322, L405, and L494 models, you will find the module behind the glovebox or under the driver’s footwell. Specifically, the Range Rover all terrain control module location often sits adjacent to the CCF (Car Configuration File) gateway. For the Range Rover Evoque all terrain control module location, look beneath the passenger seat or inside the central console. Consequently, physical access remains straightforward for an experienced retrofit technician.

Terrain Response 2 Explained

Terrain Response 2 represents the latest generation of Land Rover’s intelligent off-road technology. To clarify, this system adds Dynamic Programme and Auto mode, which continuously adjusts the vehicle’s setup. Moreover, Terrain Response 2 supports configurable parameters for throttle response, gearbox shift points, and electronic differentials. Additionally, the Discovery Sport and Velar share this same architecture.

Land Rover Terrain Response Modes

Land Rover terrain response modes include General, Grass/Gravel/Snow, Mud/Ruts, Sand, and Rock Crawl. For example, each mode recalibrates the drivetrain, stability control, and throttle map automatically. Therefore, choosing the correct mode ensures optimal traction and component longevity.

ATPC Not Available & ATPC Suspended — How to Turn Off

All Terrain Progress Control (ATPC) acts as a low-speed cruise control for off-road driving. However, drivers often encounter the ‘ATPC not available’ message when the system detects a fault. Additionally, the ‘ATPC suspended’ warning appears when system temperatures exceed safe thresholds. To turn ATPC off, press the ATPC button on the centre console or select another mode. Likewise, you can disable it through the Settings menu on the infotainment screen. In most cases, a simple reset clears the warning once the fault resolves.

Common All Terrain Control Module Symptoms

Common symptoms of a failing ATCM include intermittent warning lights, a frozen selector display, and defaulting to General mode. Therefore, early diagnosis prevents driveline damage and avoids costly secondary failures.

Fitment, Coding & Compatibility

Most JLR retrofit projects require a matching ATCM part number and a software update via SDD or Pathfinder. Consequently, we recommend sending us your VIN before ordering so we can verify the correct hardware. Moreover, our specialists can remotely configure used modules through our coding service. For example, upgrading from Terrain Response 1 requires a new switch pack, updated gateway firmware, and the appropriate ATCM.

Frequently Asked Questions

Where is the Range Rover all terrain control module located?

You will normally find it behind the glovebox, while some L405 models position it under the front carpet.

Why does my Range Rover show ATPC not available?

This message usually appears after a brake system fault or a weak battery.

How do I turn off ATPC on my Range Rover Evoque?

Press the ATPC switch on the centre console or deselect it via the main menu.
