| Module | Check Name | Parameters Measured | |--------|---------------------------|------------------------------------------------------| | 1 | Power supply stability | Voltage ripple, charging current (2A–5A range) | | 2 | Battery health (RAR) | Internal resistance, delta-V across 10 cells | | 3 | Charging plate contact | Resistance between pads & station pins (<0.5 Ω) | | 4 | Lift sensor | Hall effect response to 0–90° tilt | | 5 | Boundary signal decoding | Signal amplitude (80–120 mV typical), noise floor | | 6 | Wheel motor torque | Current draw per wheel (0.5A idle, >3A under load) | | 7 | Blade disc balance | Vibration frequency analysis (300–600 Hz) | automower serviceprogram autocheckrar 2021

2. Purpose & Scope

• Primary goal: Rapidly identify common failure points in the cutting system, charging circuit, navigation sensors, and battery management system (BMS) before physical servicing.
• Target models: Automower 300 series (315X, 320, 430X), 405X, 415X, and early 500 series.
• Key issues addressed in 2021:

  : Allows technicians to run a comprehensive "Auto Test" that checks all internal electronics, sensors, and motors in a single sequence. Manual Component Overrides Optimizing the Autonomous Lawn: An Analysis of the
