4.2 Reading and Clearing Fault Codes

The device provides access to 45,900 fault codes with clear explanations.

• To Read Codes: From the main menu, select 'OBD II' and then 'Read Codes'. The device will display current, pending, and permanent diagnostic trouble codes.
• To Clear Codes: After addressing the underlying issue, select 'Clear Codes' from the 'OBD II' menu. This will reset the Check Engine Light (MIL).

4.3 Real-time Data Monitoring

View live sensor data from the vehicle's engine control unit (ECU). This includes parameters such as engine RPM, vehicle speed, coolant temperature, fuel system status, and more. This function is crucial for diagnosing intermittent problems.

4.4 Extended Diagnostic Functions

• Freeze Frame Data: Captures a snapshot of vehicle operating conditions at the moment a fault code is set. This data can include carbon deposition, fuel quality, MAF air flow, and braking/acceleration parameters.
• I/M Readiness Status: Checks if the various emissions-related systems on the vehicle are operating correctly and are ready for an emissions inspection test.
• O2 Sensor Test: Retrieves and views O2 sensor monitor test results for the most recently completed tests from the vehicle's onboard computer.
• EVAP System Test: Initiates a leak test for the vehicle's Evaporative Emission System.
• On-Board Monitor Test (Modes 6 & 8): Retrieves test results for emission-related powertrain components and systems that are not continuously monitored.
• VIN Retrieval: Allows for immediate reading of the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN).
• Battery Voltage Monitoring: Monitors the vehicle's battery voltage to detect potential electrical issues.
• Performance Tests: Includes tests for MAF sensor air flow, fuel quality, and carbon deposition detection.
• Throttle Tests: Provides insights into throttle behavior.

4.5 Generating Diagnostic Reports

The device can generate diagnostic reports directly. These reports provide a summary of detected fault codes, live data, and test results. The Cloud Printing function allows for exporting fault codes and real-time data for further analysis.
