Steps: Select Erase Codes from Function Menu and press the OK key. Follow the on-screen instructions to complete the procedure.
Freeze Frame Data menu displays freeze frame data, a snapshot of critical vehicle operating conditions automatically recorded by the on-board computer at the time of the DTC set. It is a good function to help determine what caused the fault.
ECU Information screen displays the identification data of the control module under test, such as the control module identification string and the control module coding. 1. Select ECU Information from the menu and press the OK key. 2. A screen with detailed information of the selected control module displays.

Step 1: Scroll with the up and down arrow keys to highlight a line, if the One Graphic on the bottom is highlighted, it indicates graphing is available for the selected line. Press the function key One Graphic to display the PID graph.
Step 2: Press the function key Two Graphics to display two PID graphs in one screen
Step 3: Press the function key Merge Graph to display two PID plots in one coordinate for easy and intuitive diagnosis
Step 4: To record the data to memory of the scan tool, use the function key SAVE, and press Stop Saving to stop recording at any time.
Step 5: Press Text to return to text viewing of PID data
Step 6: Select Pause to suspend collecting data from the scan tool and use the Start key to resume

The Active Test function is used to access vehicle-specific subsystem and component tests. Available tests vary depending on the manufacturer, year and model, and only the available tests display in the menu.
During an active test, the tester outputs commands to the ECU in order to drive the actuators. This test determines the integrity of the system or parts by reading the engine ECU data, or by monitoring the operation of the actuators, such as switching a solenoid, relay, or switch, between two operating states.
Selecting Active Test opens a menu of test options that varies by make and model. Selecting a menu option activates the test. Follow all screen instructions while performing tests. The content and pattern of the on-screen information vary according to the type of test being performed. Some toggle and variable control tests display Active Test Controls at the top of the screen with data stream information below, or vice versa.
Step 1: Choose the electronic control module, such as ABS.
Step 2: Enter Special Functions
Step 3: Choose available active test such as Solenoid Tests
Also this special function is designed to provide you with quick access to the vehicle systems for various scheduled service and maintenance performances. The typical operation screen is a series of menu driven executive commands. By following the on-screen instructions to select appropriate execution options, enter correct values or data, and perform necessary actions, the system will guide you through the complete performance for various service operations.
