  • Page 5: Safety Precautions

    Safety Precautions SAFETY FIRST! SAFETY FIRST! To avoid personal injury, instrument damage and/or damage to your vehicle; do not use the CanOBD2&1 Scan Tool before reading this manual. This manual describes common test procedures used by experienced service technicians. Many test procedures require precautions to avoid accidents that can result in personal injury, and/or damage to your vehicle or test equipment.
  • Page 6 Safety Precautions SAFETY FIRST! To prevent damage to the on-board computer when taking vehicle electrical measurements, always use a digital multimeter with at least 10 MegOhms of impedance. Fuel and battery vapors are highly flammable. To prevent an explosion, keep all sparks, heated items and open flames away from the battery and fuel / fuel vapors.
