ABS & SRS Diagnostics

The NT630 Plus excels in diagnosing Anti-lock Braking System (ABS) and Supplemental Restraint System (SRS) issues:

• Read/Clear ABS/SRS DTCs: Identifies and clears fault codes related to ABS and SRS systems.
• Live Data: Monitors real-time data from ABS (e.g., wheel speed sensors, brake pressure) and SRS (e.g., airbag sensor status, wiring faults) components.
• ABS Auto Bleed: Performs automated bleeding procedures for the ABS system, crucial after brake system repairs or fluid changes to remove air.
• SAS Reset: Calibrates the Steering Angle Sensor, often required after steering system repairs or alignment.
• Oil Light Reset: Resets the oil service light after an oil change.
• EPB Reset: Resets the Electronic Parking Brake system after brake pad replacement.
• Active Test: Allows bidirectional control of specific ABS modules to test component functionality.

Maintenance

Regular software updates are crucial for maintaining the scanner's compatibility with newer vehicle models and ensuring accurate diagnostics. Updates are free for life and can be performed via WiFi directly on the device.

Troubleshooting

• Scanner Not Powering On: Ensure the diagnostic cable is securely connected to the vehicle's OBD-II port and the vehicle's ignition is on.
• Auto VIN Not Working: Some vehicles may not support automatic VIN detection. Manually enter the VIN if needed.
• Compatibility Issues: Vehicle coverage and specific functions may vary depending on the car's make, model, and year. Always verify compatibility on the FOXWELL official support site before purchase.
• Cannot Clear SRS/Airbag Codes: The NT630 Plus can read and clear ABS/SRS DTCs, but it CANNOT reset or erase any Airbag crash codes or perform programming. Ensure all vehicle issues are properly repaired before attempting to clear codes.
• Brake Pedal Feels Weak After Bleeding: Ensure brake fluid reservoir is at the proper level. The ABS auto bleed function helps remove air from the ABS module, but manual bleeding may be required first.
