4. Operating the Scanner

The NT604 Elite offers various operating modes for comprehensive vehicle diagnostics.

4.1. AutoVIN Scan

This feature automatically identifies your vehicle's VIN (Vehicle Identification Number) and retrieves essential vehicle information, saving time from manual input.

4.2. Enhanced 4-System Diagnosis

The core functionality of the NT604 Elite lies in its ability to diagnose four critical systems:

• Engine System: Read and clear check engine codes to troubleshoot engine-related issues.
• ABS System: Diagnose anti-lock braking system faults and clear warning lights.
• SRS (Airbag) System: Identify airbag system issues and clear SRS warning lights. (Note: Airbag crash/collision data cannot be cleared even if the airbag is replaced.)
• Transmission System: Scan for transmission-related fault codes and view live data to pinpoint problems.
