4. Troubleshooting with AUTOPHIX 5900
The primary purpose of the AUTOPHIX 5900 is to assist in troubleshooting vehicle issues. Here's how to effectively use it:
- Read Fault Codes: When a warning light appears on your dashboard, connect the scanner and select "Read Fault Codes" to identify the specific issue.
- Analyze Data Stream: For intermittent problems or to monitor system performance, use the "Data Stream" function to view real-time sensor data. This can help pinpoint anomalies.
- Perform Special Functions: If a specific component (e.g., battery, brake pads) has been replaced, use the relevant reset or adaptation function (e.g., Battery Registration, EPB Reset) to ensure the vehicle's computer recognizes the new part and operates correctly.
- Clear Codes: After performing repairs, use "Erase Fault Codes" to clear the DTCs. If the fault code reappears, further diagnosis or repair is needed.
- I/M Readiness Check: Before emissions testing, use this function to ensure all monitoring systems are ready, preventing test failures.
