Husqvarna Autocheck 3 Jun 2026

Husqvarna Autocheck 3: The Essential Professional Diagnostic Tool Husqvarna Autocheck 3 is the specialized proprietary software designed for Husqvarna dealers and authorized technicians to diagnose, test, and maintain the Husqvarna Automower® robotic mower ecosystem . Released as an upgrade to previous diagnostic versions, Autocheck 3 introduced a modernized user interface and support for the full range of Generation 3 mower platforms. What is Husqvarna Autocheck 3? Autocheck 3 acts as the "digital brain" for professional servicing. It connects a computer to an Automower® via a dedicated cable or Bluetooth to perform deep-level diagnostics that are not available to the average end user. While homeowners primarily use the Husqvarna Automower® Connect app for daily scheduling and basic status updates, technicians rely on Autocheck 3 for critical maintenance tasks such as: Software & Firmware Updates: Ensuring the mower has the latest performance improvements and bug fixes. Full System Diagnostics: Testing every individual sensor, motor, and internal component. Operational History: Viewing collision logs, fault codes, and total runtime data. Key Features and Capabilities The software provides a comprehensive suite of automated and manual tests to ensure every part of the robotic system is functioning correctly. Automated "Product Test": A step-by-step guided sequence that checks the battery, charging station, loop system, and communication boards. Sensor Calibration: Technicians can verify and recalibrate lift, tilt, and collision sensors to ensure safety and navigation accuracy. Motor Testing: The program can manually trigger wheel and blade motors to spin in both directions, allowing for the detection of mechanical wear or resistance. Historical Logging: It records a detailed log of all past faults, total charging cycles, and even the number of times the stop button was pressed. Compatibility and Requirements Autocheck 3 was specifically developed to support Generation 3 platforms across all Husqvarna Group brands. Access Restricted: This software is locked to authorized dealers and requires a professional login directly from Husqvarna to function. Hardware Connection: Most models connect via a physical service cable, though newer models may support Bluetooth connectivity for certain diagnostic functions. System Updates: The software is regularly updated to include support for new platforms, such as the EPOS™ (Exact Positioning Operating System) models that operate without boundary wires. Why You Might Need a Dealer to Use It

The Husqvarna Autocheck 3 is a diagnostic and display unit designed for Husqvarna’s professional chainsaws (and some other outdoor power equipment). Its "long feature" refers to its ability to store, display, and help interpret operational history and fault codes over an extended period. Here’s a breakdown of its key long-term features :

1. Extended Data Logging (3 hours or more)

Unlike basic tachometers, the Autocheck 3 continuously records engine data such as: Husqvarna Autocheck 3

RPM (maximum, minimum, and average over time) Operating hours (total runtime) Temperature (cylinder/engine temp spikes) Ignition interruptions

This data is stored for the last 3 hours of run time (or longer depending on model), allowing technicians to review what happened before a breakdown.

2. Fault Code Memory & Diagnostics

Reads and clears stored fault codes from the chainsaw’s electronic control module (ECM), including:

Over-revving events Overheating conditions Low/high idle issues Starting interruptions

Helps identify intermittent problems that don’t occur during a live test. Autocheck 3 acts as the "digital brain" for

3. Graphical Log Review

The device displays a minute-by-minute graph of RPM and temperature over the entire logging period. Service techs can scroll through the history to see exactly when a fault occurred (e.g., a sudden RPM drop under load).
