3. Operasyon
3.1 FOXWELL NT604 OBD2 Scanner Operation
The NT604 scanner connects to your vehicle's On-Board Diagnostics II (OBD-II) port to access vehicle system information.
- Jwenn pò OBD-II a: The OBD-II port is usually located under the dashboard on the driver's side.
- Konekte eskanè a: Plug the NT604's diagnostic cable into the vehicle's OBD-II port. The scanner will power on automatically.
- Vehicle Communication: The scanner will attempt to establish communication with the vehicle's ECU (Engine Control Unit). Follow on-screen prompts.
- Navigasyon nan meni prensipal: Use the navigation buttons (up, down, left, right, OK, ESC) to select desired functions from the main menu. Common functions include:
- Li Kòd: Retrieves Diagnostic Trouble Codes (DTCs) from the vehicle's systems.
- Kòd Klè: Erases DTCs from the vehicle's memory. Note: Clearing codes does not fix the underlying problem. Address the issue before clearing codes.
- Done vivan: Displays real-time sensor data from the vehicle.
- Glase ankadreman: Captures a snapshot of vehicle operating conditions at the time a fault code was set.
- Preparasyon I/M: Tcheke estati monitè ki gen rapò ak emisyon yo.
- System Diagnostic: Accesses specific vehicle systems like Engine, ABS, SRS (Airbag), and Transmission for detailed diagnostics.

3.2 FOXWELL BT100 Pro Battery Tester Operation
The BT100 Pro is designed for testing 12V automotive batteries. It can perform tests both in-vehicle and out-of-vehicle.
- Prepare batri a: Ensure battery terminals are clean and free of corrosion.
- Konekte tèsteur a:
- Konekte cl wouj laamp nan tèminal pozitif (+) batri a.
- Konekte nwa clamp nan tèminal negatif (-) batri a.
- The tester will power on automatically.
- Select Test Type:
- In-Vehicle Test: For batteries installed in the vehicle.
- Out-of-Vehicle Test: For standalone batteries.
- Chwazi Kalite batri: Choose the correct battery type (e.g., Regular Flooded, AGM Flat Plate, AGM Spiral, GEL) from the menu. Incorrect selection may lead to inaccurate results.
- Enter CCA Rating: Input the Cold Cranking Amps (CCA) rating found on the battery label.
- Fè tès la: The tester will perform the analysis and display results such as:
- Voltage
- Measured CCA
- Rezistans Entèn
- Eta Sante (SOH)
- Eta chaj (SOC)
