Key Features and Benefits of the Konnwei KW850 OBDII Scanner
The Konnwei KW850 is packed with features that make vehicle diagnostics more accessible and efficient:
- Broad Vehicle Compatibility: Designed to work seamlessly with most OBDII-compliant vehicles, including both gasoline and diesel cars, whether domestic or imported. This universal compatibility eliminates the need for multiple scanners for different car makes and models.
- Patented One-Click I/M Readiness Key: This unique feature allows for quick State Emissions readiness checks and drive cycle verification with a single button press. This is invaluable for ensuring your vehicle will pass emissions testing, saving time and potential headaches.
- Visual and Audible Readiness Verification: Bright, color-coded LED indicators and a built-in speaker provide immediate visual and audible feedback for readiness verification. This intuitive system ensures you instantly understand your vehicle’s emissions status.
- Comprehensive Code Reading: The KW850 retrieves a wide array of diagnostic trouble codes (DTCs), including generic codes (P0, P2, P3, and U0), manufacturer-specific codes (P1, P3, and U1), and pending codes. This thoroughness ensures no potential issue is overlooked.
- Check Engine Light Diagnosis: Effortlessly pinpoint the cause of the Check Engine Light (MIL) illumination. The KW850 provides clear and concise diagnostic information to guide your troubleshooting process.
- MIL Reset and Monitor Reset: Turn off the Check Engine Light (MIL), clear stored diagnostic codes, and reset emission monitors. This functionality is crucial after repairs are completed to confirm the issue is resolved.
- Enhanced OBD2 Mode 6 Monitoring: Access On-Board Monitoring Test Results for specific monitored systems. This advanced feature provides deeper insights into the performance and health of individual vehicle systems.
- Freeze Frame Data: View freeze frame data, which captures critical vehicle parameters at the moment a fault code is triggered. This snapshot of data is essential for diagnosing intermittent issues.
- Emissions Readiness Status (I/M Readiness): Displays both monitor and I/M readiness status, providing a clear picture of your vehicle’s emission system health and readiness for testing.
- Live PCM Data Stream: Read real-time live data streams from the Powertrain Control Module (PCM). This dynamic data display allows you to monitor sensor readings and system parameters as they change, crucial for diagnosing running issues.
- Live O2 Sensor Test Data: Access live O2 sensor test data to evaluate the performance of your oxygen sensors, critical components for fuel efficiency and emissions control.
- EVAP System Test Data: Retrieve EVAP (Evaporative Emission Control System) test data to diagnose leaks and issues within the fuel vapor recovery system, contributing to environmental protection.
- Live Sensor Data in Text and Graph Modes: View live sensor data in both text and graphical formats (for 1996 and newer vehicles). Graph mode provides a visual representation of data trends, making it easier to identify anomalies and patterns.
- Data Playback and Review: Record, store, and playback live sensor data. This feature is invaluable for analyzing intermittent problems or reviewing data logs at a later time.
- Troubleshooter Code Tips: Benefit from built-in troubleshooter code tips that guide technicians and DIY users towards the root cause of trouble codes, significantly reducing diagnostic and repair time.
- Real-Time Battery Voltage Monitoring: Monitor battery voltage in real-time during diagnostics. This is crucial for identifying potential battery or charging system issues that can affect diagnostic accuracy and vehicle performance.
- Built-in DTC Lookup Library: Access a comprehensive built-in DTC lookup library with code definitions. This eliminates the need to manually search for code meanings, saving time and effort.
- Vehicle Information Retrieval: Retrieve essential vehicle information including VIN (Vehicle Identification Number), CIN (Calibration Identification Number), and CVN (Calibration Verification Number).
- Internet Updatable: Keep your KW850 scanner up-to-date with the latest software and vehicle coverage via internet updates through the official Konnwei website.
- Data Printing via PC: Print diagnostic data reports via PC for record-keeping, sharing with customers, or further analysis.
