• Sensor Data: Readings from various sensors, such as engine temperature, oxygen levels, and throttle position.
• Vehicle Identification Number (VIN): A unique identifier for the vehicle.

Communication Process

1. Connection: The scan tool is connected to the OBD2 port, typically located under the dashboard.
2. Initialization: The scan tool establishes communication with the vehicle’s ECU.
3. Data Request: The user selects the desired data or diagnostic function from the software.
4. Data Retrieval: The scan tool sends a request to the ECU for the specified data.
5. Data Display: The ECU responds with the requested data, which is displayed on the scan tool’s screen or the connected computer.

Example Scenario: Diagnosing a Misfire

1. Check Engine Light: The vehicle’s check engine light illuminates, indicating a potential issue.
2. Scan Tool Connection: A technician connects a scan tool to the OBD2 port.
3. DTC Retrieval: The scan tool retrieves a DTC related to a misfire in cylinder 3 (e.g., P0303).
4. Data Analysis: The technician uses the scan tool to monitor real-time data, such as the misfire counter for cylinder 3.
5. Root Cause Identification: By analyzing the data, the technician identifies a faulty ignition coil as the cause of the misfire.
6. Repair: The technician replaces the faulty ignition coil.
7. DTC Clearing: The technician clears the DTC using the scan tool.
8. Verification: The technician verifies that the check engine light remains off and the misfire is resolved.
