1. Safety Information

For your own safety and the safety of others, and to prevent damage to the device and vehicles upon which it is used, it is important that the safety instructions presented throughout this manual be read and understood by all persons operating or coming into contact with the device.

There are various procedures, techniques, tools, and parts for servicing vehicles, as well as in the skill of the person doing the work. Because of the vast number of test applications and variations in the products that can be tested with this equipment, we cannot possibly anticipate or provide advice or safety messages to cover every circumstance. It is the automotive technician's responsibility to be knowledgeable of the system being tested. It is crucial to use proper service methods and test procedures. It is essential to perform tests in an appropriate and acceptable manner that does not endanger your safety, the safety of others in the work area, the device being used, or the vehicle being tested.

Before using the device, always refer to and follow the safety messages and applicable test procedures provided by the manufacturer of the vehicle or equipment being tested. Use the device only as described in this manual. Read, understand, and follow all safety messages and instructions in this manual.

Safety Messages

Safety messages are provided to help prevent personal injury and equipment damage. All safety messages are introduced by a signal word indicating the hazard level.

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury to the operator or to bystanders.

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury to the operator or to bystanders.

Safety Instructions

The safety messages herein cover situations the company is aware of. Autel Intelligent Technology Corp., Ltd. cannot know, evaluate or advise you as to all of the possible hazards. You must be certain that any condition or service procedure encountered does not jeopardize your personal safety.

DANGER

When an engine is operating, keep the service area WELL VENTILATED or attach a building exhaust removal system to the engine exhaust system. Engines produce carbon monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to serious personal injury or loss of life.

WARNING

It is not advised to use headphones at a high volume. Listening at high volumes for long periods of time may result in loss of hearing.

• Always perform automotive testing in a safe environment.
• Wear safety eye protection that meets ANSI standards.
• Keep clothing, hair, hands, tools, test equipment, etc., away from all moving or hot engine parts.
• Operate the vehicle in a well-ventilated work area.
• Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual transmission) and make sure the parking brake is engaged.
• Put blocks in front of the drive wheels and never leave the vehicle unattended while testing.
• Be extra cautious when working around the ignition coil, distributor cap, ignition wires and spark plugs. These components create hazardous voltages when the engine is running.
• Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.
• Do not connect or disconnect any test equipment while the ignition is on or the engine is running.
• Keep the test equipment dry, clean, and free from oil, water and grease. Use a mild detergent on a clean cloth to clean the outside of the equipment as necessary.
• Do not drive the vehicle and operate the test equipment at the same time. Any distraction may cause an accident.
• Refer to the service manual for the vehicle being serviced and adhere to all diagnostic procedures and precautions. Failure to do so may result in personal injury or damage to the test equipment.
• To avoid damaging the test equipment or generating false data, make sure the vehicle battery is fully charged and the connection to the vehicle DLC is clean and secure.
• Do not place the test equipment on the distributor of the vehicle. Strong electromagnetic interference can damage the equipment.

Bluetooth (BT) Connection

BT pairing is recommended for wireless communication, offering a working range of about 33 feet (10 m) in open areas. This allows for remote vehicle diagnostics and quick pairing in busy repair shops.

USB Cable Connection

A USB cable provides a simple and stable communication method. Ensure the USB cable is securely connected between the tablet and the V1 device. Note that the supplied USB cable is for charging; a separate USB-C to USB-C cable may be needed for vehicle communication.

No Communication Message Troubleshooting

If an "Error" message appears, indicating the tablet is not communicating with the VCI, perform the following steps:

• Ensure the VCI device is powered on.
• Verify correct network configuration and device connection for wireless use.
• Check for signal interruptions if communication is lost during diagnostics.
• Ensure the VCI device is properly positioned with its front side up.
• Move the tablet closer to the VCI device.
• For wired connections, ensure the cable is securely attached.
• Verify the VCI communication mode is lit for the selected communication type (BT or USB).
