ARB Vehicle Control Module

ARB Vehicle Control Modules: Smarter Command for the Modern 4x4

As 4x4 builds grow more capable, dashboards tend to grow more cluttered. ARB 4x4 Accessories tackled this problem head-on by developing the LINX Vehicle Accessory Interface (LX100) — a purpose-built vehicle control module that consolidates the sprawling array of switches, gauges, and monitors that come with a fully kitted overlanding rig into a single, elegant touchscreen controller.

The core challenge ARB set out to solve is a familiar one to serious off-roaders. Adding driving lights, Air Lockers, dual batteries, and air compressors to a modern 4x4 can quickly result in a dash full of out-of-place switches and a myriad of gauges stuck to the windshield or drilled into the dashboard. The LINX addresses this by offering a single point of control via its Bluetooth-enabled touchscreen display. The display mounts unobtrusively within reach of the driver, while the main control hub sits neatly out of sight, cleaning up the entire cockpit.

What the ARB LINX Controls

What separates LINX from a basic switch panel is its depth of integration. The unit ships with six pre-installed modules right out of the box:

• Front & Rear Traction Control – Automatically senses driver input and activates the air compressor to engage ARB Air Lockers, removing up to three physical switches from your dash.
• Compressor Control – Manages your onboard ARB air compressor directly through the interface.
• Accessory Switchboard – Controls up to six lighting accessories, each configurable to switch on/off manually or automatically via ignition, low beam, high beam, or reverse lights.
• Battery Monitor – Monitors up to three batteries simultaneously with custom naming and low-voltage alarms, so accessories never drain your starting power.
• Speedometer Module – Uses built-in GPS to deliver an accurate speed reading regardless of tire size, and also displays altitude and compass bearing with configurable speed limit warnings.
• Air Suspension Control – When paired with the optional LINX Pressure Control Kit, manages tire inflation and airbag suspension pressure from within or outside the vehicle at up to 33 feet away.

An Expandable, Future-Ready Platform

One of the most forward-thinking aspects of LINX is its architecture. Built on an expandable platform, it is designed to evolve alongside your build and accessory lineup. ARB has engineered it with dozens of additional modules on the horizon, meaning the unit you install today can grow in capability through updates rather than replacements. For overlanders who continuously refine their rigs, this "future-ready" approach is a significant advantage.

ARB also offers the Pressure Control Module (PCM) as a standalone entry point — a more focused controller that communicates with a dedicated smartphone app (available on iOS and Android) to handle precision tire inflation and deflation. It draws on three years of real-world LINX development and delivers the same proprietary pressure control technology in a more streamlined package for builds with fewer accessories to integrate.

Whether you are managing a fully loaded expedition truck or simply want cleaner, smarter control over your core 4x4 systems, ARB's vehicle control modules represent a thoughtful, engineer-driven solution backed by decades of off-road product development.
