Last updated: 7 May 2026

⚠ DANGER — Do not use while driving

Never operate the Steer mobile application or interact with the ST013B device while the vehicle is in motion. Pull over and park safely with the engine running, or with ignition in position II, before reading data, clearing codes or changing settings. Distracted driving causes serious injury and death. The driver remains fully responsible for safe operation of the vehicle at all times. Steer is a diagnostic aid only and is not a substitute for professional inspection or qualified vehicle repair.

📱 Quick Start

  3. Turn the ignition key to position II (engine OFF, electrics ON), or for keyless-start vehicles, press the START button without depressing the brake pedal (accessory mode)
  4. Open the Steer app and follow the on-screen pairing instructions
  5. Once paired, you may start the engine — Steer will begin reading vehicle data
