Understanding OBD-II Compliance
The MS509 car scanner is designed to be universally compatible with OBD-II compliant vehicles. Since 1996, the Environmental Protection Agency (EPA) has mandated that all cars and light trucks sold in the United States must be OBD-II compliant. This standard includes vehicles from domestic, Asian, and European manufacturers. While most 1994 and 1995 gasoline vehicles are not OBD-II compliant, some exceptions exist. To verify OBD-II compliance for a 1994 or 1995 vehicle, check the Vehicle Emissions Control Information (VECI) label, typically located under the hood or near the radiator. An OBD-II compliant vehicle will have a label clearly stating “OBD II Certified.” Furthermore, all OBD-II compliant vehicles are required to have a standardized sixteen-pin Data Link Connector (DLC), usually found under the dashboard. For successful diagnostics with the MS509, ensure your vehicle has this 16-pin DLC and the VECI label confirms OBD-II compliance.
Navigating Common Issues: Troubleshooting Your MS509 Scanner
Encountering issues while using your MS509 car scanner is rare, but understanding potential problems and their solutions can ensure a smooth diagnostic process:
Vehicle Linking Error: If the MS509 fails to communicate with your vehicle’s ECU (Engine Control Unit), consider these troubleshooting steps:
- Ignition Check: Verify that the vehicle ignition is turned ON.
- DLC Connection: Ensure the MS509’s OBD II connector is securely plugged into the vehicle’s DLC.
- OBD2 Compliance: Double-check that your vehicle is indeed OBD2 compliant.
- Reset Procedure: Turn the ignition OFF, wait for approximately 10 seconds, and then turn it back ON before re-attempting the test.
- ECU Integrity: Rule out the possibility of a defective vehicle control module.
Operating Error (Scanner Freezing): If the MS509 freezes during operation, it may be due to an exception or a slow ECU response. 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 vehicle ignition OFF, wait 10 seconds, and then turn it back ON before continuing diagnostics.
Scanner Power Issues: If the MS509 fails to power up or operates erratically, check the following:
- DLC Connection Security: Confirm that the MS509’s OBD II connector is firmly connected to the vehicle’s DLC.
- DLC Pin Inspection: Examine the DLC pins for any bending or breakage. Clean the pins if necessary to ensure a good connection.
