OBD2 and EOBD Compliance: Ensuring Compatibility

The Autel MaxiScan MS509 OBD2 EOBD Scanner is specifically engineered to be compatible with all OBD II compliant vehicles. This includes vehicles sold in the United States from 1996 onwards, as mandated by the EPA, encompassing domestic, Asian, and European makes. OBD-II compliance is typically indicated on the Vehicle Emissions Control Information (VECI) Label, usually found under the hood. For OBD II compliance, vehicles must also feature a standardized 16-pin Data Link Connector (DLC) located under the dashboard. EOBD (European On-Board Diagnostics) is the European equivalent of OBD-II, and the MS509 supports both standards, making it a versatile tool for a global market.

Supported Protocols and Diagnostic Capabilities

The MaxiScan MS509 supports a wide array of OBD-II protocols, ensuring it can communicate with various vehicle systems:

• ISO 15765-4 CAN (Controller Area Network) in different ID and baud rate configurations.
• ISO 14230-4 KWP 2000 (Keyword Protocol 2000) with fast and 5-baud initialization.
• ISO 9141-2 (ISO 9141)
• SAE J1850 VPW (Variable Pulse Width Modulation)
• SAE J1850 PWM (Pulse Width Modulation)

This extensive protocol support allows the MS509 to perform comprehensive diagnostics, reading and clearing both generic and manufacturer-specific trouble codes, and accessing live data for a wide range of vehicle systems.

Troubleshooting Common Issues with the MS509

Encountering issues? Here are some troubleshooting tips for common scenarios:

• Vehicle Linking Error: If the scanner fails to communicate with the vehicle’s ECU, ensure the ignition is ON, the OBD II connector is securely plugged into the vehicle’s DLC, and the vehicle is OBD2 compliant. Try turning the ignition off and on again.
• Operating Error (Scanner Freezes): If the scan tool freezes, reset the tool by holding the POWER button for a few seconds. Also, try turning the vehicle ignition off and on again.
• Scan Tool Doesn’t Power Up: Check the OBD II connector for secure connection and inspect the DLC pins for damage. Clean the pins if necessary.
