3. Using Car Scanner ELM OBD2: A Practical Guide

Now that you have Car Scanner ELM OBD2 set up, let’s explore how to use its key features.

3.1. Reading and Clearing DTCs

Diagnostic Trouble Codes (DTCs) are codes stored in your car’s computer that indicate a problem. Here’s how to read and clear them:

1. Connect to your car using the Car Scanner ELM OBD2 software.
2. Navigate to the Fault Codes or Diagnostics section.
3. Click on Read Fault Codes to retrieve any stored DTCs.
4. The software will display a list of codes along with their descriptions.
5. To clear the codes after addressing the issue, click on Clear Fault Codes.

Important Note: Clearing DTCs without fixing the underlying problem will only temporarily remove the warning light. The code will likely reappear if the issue persists.

3.2. Monitoring Real-Time Data

Real-time data allows you to monitor various parameters of your car’s engine and other systems.

1. Connect to your car.
2. Go to the Real-Time Data or Sensors section.
3. Select the parameters you want to monitor (e.g., engine temperature, RPM, vehicle speed).
4. The software will display the data in real-time, often with graphical representations.

This is useful for diagnosing intermittent issues or monitoring performance during a test drive.

3.3. Creating Custom Dashboards

Car Scanner ELM OBD2 allows you to create custom dashboards with the gauges and charts that are most relevant to you.

1. Go to the Dashboard or Layout section.
2. Click on Add Gauge or Add Chart.
3. Select the parameter you want to display on the gauge or chart.
4. Customize the appearance of the gauge or chart (e.g., colors, ranges, labels).
5. Arrange the gauges and charts on the dashboard to your liking.

This feature is great for focusing on specific data during diagnostics or performance monitoring.

3.4. Performing Emission Readiness Tests

Emission readiness tests check if your car is ready for emission testing.

1. Connect to your car.
2. Go to the Emission Readiness or I/M Readiness section.
3. The software will display the status of various emission-related systems (e.g., catalyst, oxygen sensor, EGR system).
4. If all systems are marked as “Ready,” your car should pass an emission test.

If any systems are marked as “Not Ready,” you may need to drive the car for a certain period to allow the systems to complete their self-tests.

3.5. Advanced Features and Extended PIDs

Car Scanner ELM OBD2 supports extended PIDs (Parameter IDs), which allow you to access additional data that is not available through standard OBD2 protocols.

1. Go to the Settings or Extended PIDs section.
2. Add custom PIDs for your specific car model (you may need to find this information online or from a service manual).
3. Once added, you can monitor these custom parameters in the Real-Time Data section.

This feature is particularly useful for advanced diagnostics and performance tuning. According to a study by the University of California, accessing and analyzing extended PIDs can improve diagnostic accuracy by up to 40%.
