Introducing OBD JScan, the comprehensive mobile OBD-II scanner app designed for Android devices. This powerful app allows users to connect their phone to a vehicle’s OBD-II port and access critical diagnostic information, perform system checks, and monitor real-time data streams. Perfect for both everyday drivers and automotive professionals, OBD JScan transforms your smartphone into a versatile diagnostic tool.

The OBD JScan provides significant value by simplifying complex vehicle diagnostics that were once only available through expensive hardware. Its intuitive interface makes accessing crucial information like Engine Control Unit (ECU) data, sensor readings, and stored trouble codes straightforward, empowering users to better understand their vehicle’s performance.

App Features

• Live Data Monitoring: View real-time sensor information including engine RPM, vehicle speed, coolant temperature, and more. This feature helps diagnose current issues and monitor engine performance during driving, allowing drivers to identify potential problems before they worsen.
• DTC Reading and Clearing: Read and clear diagnostic trouble codes stored in your vehicle’s Engine Control Unit (ECU). This functionality enables quick checks after repairs and provides detailed insights into engine issues, saving time and money at the repair shop.
• OBD-II PIDs Access: Access a wide range of Parameter Identifiers (PIDs) from your car’s control modules, including fuel injection, ignition timing, and emissions data. This capability allows for deep dives into specific system performance, making it invaluable for enthusiasts modifying their vehicles.
• Freeze Frame Data: Retrieve the data snapshot captured when a specific diagnostic code was triggered. This feature helps technicians understand the conditions under which a fault occurred, making accurate diagnosis significantly more efficient than guesswork.
• Multiple Language Support: View all interface text, codes, and data interpretations in your preferred language. This is especially beneficial for international users who may be more comfortable troubleshooting in their native tongue rather than English.
• PID Customization: Create custom PID groups for frequent monitoring of specific parameters. This allows mechanics and tuners to track key performance metrics without scrolling through extensive lists, streamlining the diagnostic process significantly.
