2. Setup

Follow these steps to set up your THINKCAR THINKSCAN 662 OBD2 Scanner:

1. Unboxing: Carefully remove the THINKSCAN 662 device, the OBD2 diagnostic cable, and the USB charging cable from the packaging.
2. Powering the Device: The device is corded and charges directly from the vehicle's OBD2 port. Connect the diagnostic cable to the 9-pin serial connector port located at the top of the THINKSCAN 662 device.
3. Connecting to Vehicle: Locate your vehicle's OBD2 port (typically under the dashboard on the driver's side). Plug the other end of the diagnostic cable into the vehicle's OBD2 port. Ensure the vehicle's ignition is in the 'ON' position (engine can be off or running, depending on the diagnostic task).
4. Initial Boot-up: The device will power on automatically once connected to the vehicle. If not, press the power button located on the top right side of the device.
5. Charging: The device charges via the OBD2 port when connected to a vehicle. A separate USB charging cable is provided for software updates or if external charging is required. The device also features a USB port and an SD card slot on the side for data transfer and storage.

3. Operating Instructions

The THINKSCAN 662 features a 6.2-inch touchscreen display for intuitive navigation. Use the touchscreen or the physical buttons on the right side of the device to interact with the menus.

3.1. Main Menu Navigation

The main menu provides access to various functions:

• Diagnose: Initiates vehicle diagnostics.
• Maintenance: Accesses special reset and service functions.
• Upgrade: For software updates.
• More: Contains additional tools and settings.

3.2. Vehicle Diagnostics

To perform a vehicle diagnostic scan:

1. From the main menu, select Diagnose.
2. Choose AutoSearch to automatically identify the vehicle's VIN, make, model, and year for quick access to diagnostics. Alternatively, select Diagnose for manual vehicle selection or OBD for standard OBD2 functions.
3. After vehicle identification, you can select from options like Health Report, System Scan, or System Selection.
4. A Health Report or System Scan will quickly communicate with available modules (e.g., Engine Control Module (ECM), Transmission Control Module (TCM), Electronic Brake Control Module (EBCM), Inflatable Restraint Sensing And Diagnostic Module (IRSDM)) to check for Diagnostic Trouble Codes (DTCs).
5. To view live data, navigate to the Engine Control Module (ECM) or other relevant module, then select Read Data Stream. You can select specific data parameters (PIDs) to monitor. The device supports displaying up to four data streams simultaneously in a graphical format. You can switch between Metric and Imperial units.
6. For active testing, select Actuation Test within a module. This allows you to send commands to specific components (e.g., Air Conditioning (A/C) Compressor Clutch Relay, Cooling Fan, Fuel System) to verify their functionality.

5. Troubleshooting

If you encounter issues with your THINKSCAN 662, consider the following:

• Device Not Powering On: Ensure the diagnostic cable is securely connected to both the device and the vehicle's OBD2 port. Verify the vehicle's ignition is on. The device draws power from the OBD2 port.

• Software Issues: Utilize the Upgrade function to ensure your device has the latest software. Lifetime free updates are available.
• Incorrect Readings/Functions: Confirm the correct vehicle information (VIN, make, model, year) has been automatically or manually selected.
