Connect Scanner: Plug the Autel OBD2 scanner into the DLC.
Turn On Ignition: Turn the ignition to the “ON” position without starting the engine.
Verify Connection: Confirm that the scanner powers on and establishes a connection with the vehicle’s computer.

4.3 Entering Vehicle Information

The scanner will prompt you to enter vehicle information, such as:

VIN (Vehicle Identification Number): A unique identifier for your vehicle.
- Location: Lower corner of the windshield on the driver’s side, door jamb, or vehicle registration.
Make and Model: Select the vehicle’s make and model from the scanner’s menu.
Year: Enter the vehicle’s year of manufacture.
Engine Type: Specify the engine type (e.g., gasoline, diesel).

Providing accurate vehicle information ensures that the scanner retrieves the correct diagnostic data.

4.4 Reading Diagnostic Trouble Codes (DTCs)

Navigate to Diagnostic Menu: Select the “Diagnostics” or “Scan” option from the main menu.
Initiate Scan: Start the scanning process, which may take a few minutes.
View DTCs: The scanner will display any stored DTCs, along with their descriptions.

4.5 Understanding Diagnostic Trouble Codes (DTCs)

DTCs are standardized codes that indicate specific problems within the vehicle’s systems. Each code consists of a letter followed by four numbers:

First Letter: Indicates the system affected:
- P: Powertrain (engine, transmission)
- B: Body (airbags, power steering)
- C: Chassis (brakes, suspension)
- U: Network (communication issues)
First Number: Indicates whether the code is generic (0) or manufacturer-specific (1).
Remaining Numbers: Specify the exact problem.

For example, a code like P0300 indicates a random or multiple cylinder misfire in the engine.

4.5.1 Common DTCs and Their Meanings

DTC	Description	Possible Causes
P0171	System Too Lean (Bank 1)	Vacuum leak, faulty O2 sensor, fuel system issue
P0300	Random/Multiple Cylinder Misfire	Faulty spark plugs, ignition coils, fuel injectors
P0420	Catalyst System Efficiency Below Threshold	Faulty catalytic converter, O2 sensors
P0442	Evaporative Emission Control System Leak Detected (Small Leak)	Loose fuel cap, damaged fuel lines, faulty purge valve
P0505	Idle Air Control System Malfunction	Faulty IAC valve, vacuum leak, throttle body issues
