2. Plug the scanner into the OBD2 port.
3. Turn the ignition to the “ON” position without starting the engine.

4.2 Reading Diagnostic Trouble Codes (DTCs)

1. Navigate to the “Read Codes” or “Diagnostic Codes” option on the scanner.
2. The scanner will display any stored DTCs.
3. Record the codes and their descriptions.

4.3 Interpreting The Codes

OBD2 codes consist of five characters:

• The first character indicates the system (e.g., P for Powertrain, B for Body, C for Chassis, U for Network).
• The second character indicates whether the code is generic (0) or manufacturer-specific (1).
• The third character indicates the subsystem (e.g., 1 for Fuel and Air Metering, 2 for Fuel and Air Metering – Injector Circuit).
• The last two characters indicate the specific fault.

4.4 Clearing Codes

After repairing the issue, you can clear the codes using the “Clear Codes” or “Erase Codes” option on the scanner. Note that clearing codes does not fix the underlying problem; it only resets the warning lights.

4.5 Using Live Data

1. Select the “Live Data” or “Data Stream” option on the scanner.
2. Choose the parameters you want to monitor (e.g., engine RPM, coolant temperature).
3. Observe the data while the engine is running to identify any abnormalities.

4.6 Using Freeze Frame Data

1. Access the “Freeze Frame” option on the scanner.
2. View the data recorded when the fault code was triggered.
3. Analyze the data to understand the conditions that led to the problem.
