Key Features and Functions of the MaxiScan MS509 OBD2 Scanner
The MaxiScan MS509 OBD2 scanner is packed with features designed to streamline vehicle diagnostics and provide users with in-depth insights into their car’s performance. Here’s a breakdown of its core functionalities:
- Broad Vehicle Compatibility: Works seamlessly with all OBDII compliant vehicles manufactured from 1996 onwards, including models from the US, Europe, and Asia. This wide compatibility ensures you can use this single tool across a range of car makes and models.
- Check Engine Light Diagnosis: Effortlessly identifies the root cause of the Check Engine Light (MIL) illuminating on your dashboard, helping you pinpoint problems quickly and efficiently.
- Extensive Code Support: Reads both generic (P0, P2, P3, and U0) and manufacturer-specific (P1, P3, and U1) Diagnostic Trouble Codes (DTCs). This comprehensive code reading capability provides a detailed understanding of potential issues, ranging from common emissions problems to more intricate manufacturer-specific faults.
- MIL Reset and Monitor Reset: Allows you to turn off the Check Engine Light (MIL), clear diagnostic codes, and reset OBDII monitors. This is crucial after repairs to ensure the system is properly reset and ready for further monitoring.
- DTC Definitions Display: Shows clear and concise DTC definitions directly on the unit’s screen, eliminating the need to look up codes manually and saving valuable diagnostic time.
- Freeze Frame Data: Captures freeze frame data, which provides a snapshot of critical engine parameters at the moment a fault occurred. This data is invaluable for understanding the conditions under which a problem arose.
- I/M Readiness Status: Displays monitor and I/M readiness status, essential for emissions testing. This feature allows you to verify if your vehicle is ready for an emissions test, helping you avoid unexpected failures.
- Pending Codes Identification: Identifies pending codes, which are intermittent faults that haven’t yet triggered the MIL. Addressing pending codes proactively can prevent more serious issues down the line.
- Live Data Stream: Reads and displays live PCM datastream, providing real-time data from your vehicle’s sensors. This live data is crucial for monitoring engine performance and identifying sensor malfunctions.
- O2 Sensor Test Data: Displays live O2 sensor test data, allowing you to evaluate the performance of your oxygen sensors, which are critical for fuel efficiency and emissions control.
- Data Graphing: Graphs live data for 1996 and newer vehicles, providing a visual representation of sensor data for easier analysis and trend identification.
- Data Storage and Playback: Reads, stores, and plays back live sensor data, allowing for off-vehicle data review and analysis. This feature is particularly useful for intermittent problems that are difficult to capture in real-time.
- Multilingual Support: Offers multilingual menu and DTC definitions in English, Spanish, French, German, and Dutch, catering to a diverse user base.
- Module Presence Test: Performs modules present test to verify the functionality and presence of different vehicle modules.
- Vehicle Information Retrieval: Retrieves vehicle information, including VIN (Vehicle Identification Number), CIN (Calibration Identification Number), and CVN (Calibration Verification Number), which is essential for accurate diagnostics and vehicle identification.
- CAN and OBD-II Protocol Support: Supports CAN (Controller Area Network) and all other current OBD-II protocols, ensuring compatibility with modern vehicle communication systems.
- Built-in DTC Lookup Library: Features a built-in OBD-II DTC lookup library, providing quick access to code definitions directly within the tool.
- Large Backlit LCD Screen: Equipped with a large, easy-to-read backlit LCD screen for clear visibility in various lighting conditions.
- Software Upgradeable: Software is upgradeable via the internet, ensuring your tool stays current with the latest vehicle models and diagnostic capabilities.
- PC Printing Capability: Allows data printing via PC, enabling you to generate reports and keep records of diagnostic sessions.

Understanding OBDII Compliance
OBDII (On-Board Diagnostics II) is a standardized system mandated in the United States by the EPA for all cars and light trucks manufactured from 1996 onwards. This standard applies to vehicles sold in the US, including domestic, Asian, and European brands. OBDII systems monitor various vehicle components and systems related to emissions and engine performance. Compliance ensures vehicles meet specific emission standards and allows for standardized diagnostics.
While most 1996 and newer vehicles are OBDII compliant, some 1994 and 1995 models might also be. To confirm OBDII compliance for a 1994 or 1995 vehicle, check the Vehicle Emissions Control Information (VECI) label, typically found under the hood or near the radiator. An OBDII compliant vehicle will have “OBD II Certified” designated on this label. Furthermore, all OBDII compliant vehicles are required to have a standardized 16-pin Data Link Connector (DLC), usually located under the dashboard.
To use the MaxiScan MS509 effectively, ensure your vehicle is OBDII compliant by verifying the presence of a 16-pin DLC and checking for the “OBD II Certified” designation on the VECI label.
Troubleshooting Common Issues with the MS509 Scanner
Encountering issues with your MaxiScan MS509 OBD2 scanner is rare, but understanding basic troubleshooting steps can save time and frustration. Here are solutions to common problems:
Vehicle Linking Error: If the scanner fails to communicate with the vehicle’s ECU (Engine Control Unit), check the following:
- Ignition Status: Ensure the vehicle’s ignition is turned ON.
- OBDII Connector Security: Verify that the MS509’s OBDII connector is securely plugged into the vehicle’s DLC.
- OBDII Compliance: Confirm that the vehicle is indeed OBDII compliant.
- Reset Procedure: Turn the ignition OFF, wait for 10 seconds, and then turn it back ON before retrying the test.
- Control Module Check: In rare cases, the vehicle’s control module might be defective.
Operating Error (Scanner Freezes): If the scan tool freezes, it might be due to an exception or a slow response from the vehicle’s ECU. To reset the tool:
- Power Reset: Press and hold the POWER button for at least 2 seconds to reset the scanner.
- Vehicle Reset: Turn the ignition OFF, wait for 10 seconds, and then turn it back ON before continuing the diagnostic process.
Scanner Doesn’t Power Up: If the MS509 fails to power on, consider these checks:
- OBDII Connector Security: Ensure the OBDII connector is firmly connected to the vehicle’s DLC.
- DLC Pin Inspection: Check the DLC pins for any bending or breakage. Clean the pins if necessary to ensure a good connection.
