1. Introduction
The Jexiwe V119 OBD2 Car Code Scanner is a professional diagnostic tool designed to help you quickly and accurately identify engine fault codes, perform battery voltage tests, and check I/M readiness for emission-related issues in OBDII protocol cars. This manual provides detailed instructions for safe and effective use of your device.
2. Safety Measures and Warnings
To prevent physical injuries or damage to vehicles and the decoder, please read this operating manual before using this instrument on the vehicle, and comply with the following safety measures:
- Detection shall be carried out in a safe environment.
- Wear eye protective devices in accordance with ANSI standard.
- Keep clothes, hair, hands, tools, and test equipment away from all motor heating components.
- Operate the vehicle in a well-ventilated area: exhaust gas is harmful to the human body.
- Place a block plate in front of the drive wheel; ensure the vehicle is guarded during the test operation.
- Be more careful when operating near the ignition wire and spark plug of ignition coil distributor cover. These components will generate dangerous voltage when the engine is running.
- Place the gearbox in PARK (automatic gearbox) or NEUTRAL (manual gearbox), and ensure the parking brake is connected.
- Keep fire extinguishers for petrol/chemical/electrical fires nearby.
- Do not connect or disconnect any test equipment when the ignition switch is open or the engine is running.
- Keep the decoder dry, clean, and free from oil, water, or lubricants. Wipe the decoder with a clean cloth and gentle cleaner if necessary.
