← Back to All Questions
Home › Questions & Answers › How Do I Run a Full-System Scan and Clear All Fault Codes?
Beginner Applies to: UCAN-II, UCAN-II Pro

You can use your scanner to scan all vehicle modules and clear stored fault codes in one step:

  1. Connect to your vehicle’s OBD-II port
  2. Select your make and use SmartVIN
  3. Choose Quick Scan to read all control modules
  4. Review the fault codes
  5. After completing repairs, select Clear All Codes

This is useful for diagnosing issues across multiple systems (engine, ABS, transmission, etc.) and confirming repairs are successful.
