The Autel MaxiScan MS509 is a powerful and versatile OBDII/EOBD code reader designed for both professional technicians and home users. This comprehensive diagnostic tool supports all nine OBDII test modes on OBDII EOBD compliant vehicles, enabling accurate diagnosis of even the most challenging automotive problems. Its user-friendly interface and advanced features make it an essential tool for anyone who wants to understand and address their vehicle’s engine performance.
Understanding the Power of the MaxiScan MS509
The MS509 quickly and easily accesses engine-based EOBD fault codes, providing clear and concise DTC (Diagnostic Trouble Code) definitions on its large, backlit LCD screen. This CAN-enabled scanner retrieves generic (P0, P2, P3, and U0) and manufacturer-specific (P1, P3, and U1) codes for comprehensive emissions diagnostics. Beyond code retrieval, the MS509 turns off the MIL (Malfunction Indicator Lamp), stores freeze frame data for later review, and displays monitor and I/M readiness status.

Understanding OBDII Compliance and the MaxiScan MS509
The MS509 is designed for OBDII compliant vehicles, mandated by the EPA for all 1996 and newer vehicles sold in the United States. This includes domestic, Asian, and European vehicles. Some 1994 and 1995 gasoline vehicles may also be OBDII compliant. To verify, check the Vehicle Emissions Control Information (VECI) label under the hood or by the radiator. The label will indicate “OBD II Certified” if compliant. OBDII compliant vehicles have a 16-pin Data Link Connector (DLC).
Troubleshooting with the MaxiScan MS509
The MS509 provides guidance for common issues:
- Vehicle Linking Error: Ensure the ignition is ON, the connector is secure, and the vehicle is OBD2 compliant. Try turning the ignition off for 10 seconds and then back on.
- Operating Error: If the tool freezes, press and hold the power button for 2 seconds to reset.
- Power Up Issues: Check connector security, DLC pin condition, and clean the pins if necessary.
