This review delves into the features, functionalities, and overall value of this popular scan tool, providing an expert perspective to help you decide if it’s the right tool for your automotive needs.
Key Features and Benefits
The Konnwei KW680 is packed with features designed to make vehicle diagnostics accessible and efficient. Let’s explore some of its standout capabilities:
Multilingual Support and User-Friendly Interface
Navigating diagnostic tools should be straightforward, and the KW680 excels in user experience. It offers a multilingual interface supporting up to 8 languages including English, Spanish, Portuguese, French, Russian, German, Dutch, and Italian. This broad language support ensures accessibility for a diverse user base. The intuitive menu and button layout further simplify operation, making it easy for both beginners and experienced users to navigate through diagnostics.
Vivid Color Display and Audible Feedback
Gone are the days of squinting at monochrome screens. The KW680 features a high-resolution TFT color display, presenting diagnostic information clearly and effectively. Color-coded LEDs and a built-in speaker provide visual and audible cues for readiness verification, enhancing the speed and accuracy of your diagnostics. This combination ensures you don’t miss important status indicators, even in noisy environments.
One-Click I/M Readiness Key
Emissions testing can be a nerve-wracking experience for any car owner. The patented One-Click I/M Readiness Key on the KW680 provides instant access to emissions readiness status. This feature allows you to quickly check if your vehicle is ready for smog checks, saving you time and potential headaches at the testing center. By identifying potential emission-related issues beforehand, you can address them proactively.
Real-time Battery Monitoring
A healthy car battery is fundamental to vehicle reliability. The KW680 offers real-time battery voltage monitoring during diagnostics. This is crucial for preventing unexpected issues during the diagnostic process, especially when dealing with older vehicles or potential battery problems. The tool displays voltage levels before and after starting the engine, giving you insights into your battery’s condition and charging system effectiveness.
Data Logging and Playback
Troubleshooting intermittent issues can be challenging. The integrated memory card in the KW680 allows you to store trouble codes, live data streams, and freeze frame data. This invaluable feature enables you to record diagnostic sessions and review the data later, even when you are away from the vehicle. Playback functionality helps in analyzing historical data to pinpoint elusive problems.
USB Data Printing and Upgrades
The KW680 is designed to be future-proof and user-friendly in data handling. It supports data printing via a USB cable, allowing you to generate hard copies of diagnostic reports. This is beneficial for record-keeping or sharing information with mechanics. Furthermore, internet updates via the USB port ensure that your tool is always equipped with the latest software and vehicle coverage, keeping it compatible with newer models and diagnostic protocols.
Core Diagnostic Functions
Beyond its user-friendly features, the Konnwei KW680 delivers a comprehensive suite of diagnostic functions:
Broad Vehicle Compatibility
The KW680 is designed to work with all 1996 and later OBDII compliant vehicles sold in the US, Europe, and Asia. This wide compatibility makes it a versatile tool for households with multiple vehicles or for mechanics working on diverse car brands. It supports all OBD-II protocols, including CAN, ensuring it can communicate with a vast majority of modern vehicles.
Check Engine Light Diagnosis
The dreaded “Check Engine Light” (MIL) can cause anxiety for any driver. The KW680 quickly determines the cause of this warning light, reading both generic (P0, P2, P3, and U0) and manufacturer-specific (P1, P3, and U1) diagnostic trouble codes (DTCs). Understanding why the light is on is the first step towards effective repair.
Comprehensive Code Reading and Clearing
The tool doesn’t just read codes; it provides detailed DTC definitions right on the screen, eliminating the need to constantly look up codes online. It also empowers you to turn off the Check Engine Light, clear codes, and reset monitors after repairs are completed. This functionality is essential for verifying that repairs have been successful and for resetting the vehicle’s computer system.
Freeze Frame and Live Data
The KW680 captures freeze frame data, showing the vehicle’s condition at the moment a fault code was triggered. This snapshot of data provides valuable context for understanding the conditions under which the problem occurred. It also displays live PCM datastream and live O2 sensor test data, giving you a real-time view of critical engine parameters and sensor readings. Graphing capabilities for 1996 and newer vehicles further enhance data interpretation.
I/M Readiness and Emissions Testing
In addition to the one-click key, the KW680 thoroughly supports I/M readiness status checks, essential for emissions testing. It identifies pending codes and performs modules present tests, ensuring you have a complete picture of your vehicle’s emission system health.
Vehicle Information Retrieval
Retrieving vehicle-specific information is crucial for accurate diagnostics and part identification. The KW680 retrieves vehicle information including VIN (Vehicle Identification Number), CIN (Calibration Identification Number), and CVN (Calibration Verification Number). This data ensures you are working with the correct vehicle specifications during diagnosis and repair.
Built-in DTC Lookup
Having a built-in OBD-II DTC lookup library is a significant advantage. The KW680 eliminates the need for external code lookups, providing code definitions directly on its large, easy-to-read backlit LCD screen. This feature saves time and streamlines the diagnostic process.
Battery Health Monitoring Feature
The KW680 includes a dedicated battery check function that offers real-time voltage monitoring. It provides clear indicators of battery status:
- 10.8V-11.8V [Before Starting]: Slightly Low – Difficult to start, consider charging.
- 11.8V-12.8V [Before Starting]: Normal.
- 12.8V-13.2V [After Starting]: Too Low – Charging issue possible, check electrical load.
- 13.2V-14.8V [After Starting]: Normal.
- >14.8V [After Starting]: Too High – Potential battery damage, check voltage regulator.
This feature works on 12V vehicle batteries and is plug-and-play, offering immediate insights into battery health.
Ease of Use and Updates
The Konnwei KW680 is designed for ease of use. It’s a plug-and-play scanner, requiring no complex setup. Lifetime free updates are supported via PC (Windows XP-10, not compatible with MAC systems). Updating is straightforward: simply press any button, connect to a PC via USB, and download the update software from the website indicated on the scanner screen. The ability to print diagnostic reports further enhances its practicality for record-keeping and analysis.
LED Indicators for Quick Status Checks
Three LED indicators on the KW680 surface provide quick visual cues:
- Green LED: Indicates the engine system is good.
- Yellow LED: Indicates pending fault codes, requiring attention.
- Red LED: Indicates a serious vehicle problem.
These indicators offer an immediate, at-a-glance assessment of your vehicle’s diagnostic status.
Prepare for Emissions Testing
The KW680 is invaluable for pre-emissions test checks. It allows you to test misfire, fuel system, and comprehensive components before going for a smog check. By identifying potential issues beforehand, you can address them, ensuring your vehicle is more likely to pass the emission inspection, saving both time and money.
