Unlock the Power of Your Car Keys with VD31
Looking for a reliable tool to test your car keys? The VD31 is equipped with cutting-edge technology that allows you to easily test your vehicle’s key functionality, ensuring your keys are working properly and efficiently. This feature helps users quickly verify whether a key is functioning correctly without the need for complicated procedures, saving time and providing confidence before attempting vehicle diagnostics or key programming.
Full OBDII Car Code Reader
The VD31 can perform all 10 OBD2 standard tests, including reading and clearing fault codes, monitoring real-time data, retrieving freeze frame data, one-click I/M readiness checks, on-board monitor tests, component tests, O2 sensor tests, vehicle information retrieval, and module presence verification. With this full set of diagnostic functions, users can thoroughly assess the health of the vehicle’s systems, identify potential issues, and maintain optimal performance efficiently.
Patented One-Click Smog Check
The VD31 features a patented I/M One-Click Readiness Key that allows users to perform a quick state emissions readiness check (smog check) and drive cycle verification. This tool simplifies emissions testing by providing an immediate assessment of whether a vehicle is ready for inspection, reducing the time and effort required for manual verification while ensuring compliance with emission standards.
Real-Time Battery Monitoring
To ensure the vehicle is in good condition for accurate diagnostics, the VD31 includes a battery voltage test function that can check the real-time voltage of your vehicle. This allows users to monitor battery performance, detect weak or abnormal voltage conditions, and prevent inaccurate diagnostic readings caused by insufficient power, ensuring all tests are performed safely and reliably.
Quick DTC Definition Lookup
A Diagnostic Trouble Code (DTC) is generated when a fault occurs in a vehicle's monitored system, triggering a warning light on the instrument panel. The VD31 car check engine scanner retrieves generic, manufacturer-specific, pending, and permanent codes, displays their definitions on the TFT screen, helps users identify the root causes of issues, and allows for safe code clearing once the problem is resolved. This capability ensures precise troubleshooting and helps maintain the vehicle’s operational reliability.
Unmatched Vehicle Compatibility
The VdiagTool VD31 universal OBD2 scanner supports all OBDII protocols, including J1850 PWM, J1850 VPW, ISO9141-2, KWP2000, and CAN. It is compatible with most American, European, and Asian vehicles sold in the US after 1996 that are OBDII compliant and use 12 volts, including sedans, trucks, SUVs, and minivans. This extensive compatibility allows users to rely on a single tool for a wide range of vehicles, making it versatile and efficient for professional or personal use.
