This feature automatically displays previously saved fault code search (FCS) results when re-entering the function, enabling comparison before and after maintenance. It activates if the VIN, model year, and data age (within 7 days) match. Users can rescan or use the current FCS button for new searches. The feature can be deactivated in settings, and troubleshooting tips address VIN/model year mismatches, data age limits, connection issues, and app glitches.
1. Key Benefits and Use Cases
This feature is designed to be applicable in the following situations:
- When re-entering the FCS function, previously searched fault code results are automatically displayed.
- Previous search results are immediately displayed to compare the vehicle's status before and after maintenance.
- It is useful when the wait time for repeatedly scanning the same vehicle is burdensome.
[Feature Improvement]
Current Behavior: Results reset when moving between functions.
Improvement: Previous results can be reused, allowing comparison before and after maintenance.
2. Conditions for Automatic Display
Previously saved FCS results are automatically loaded if all three of the following conditions are met:
- Same VIN
- Same model year
- Data is within 7 days of the initial search
3. Usage Guide
3-1. Behavior upon entering the FCS function
- If there are no previous results: Automatically performs a new fault code search based on the selected controllers.
- If there are previous results: Existing search results are automatically displayed if the conditions are met.
3-2. Rescan Button 
Immediately performs a new fault code search based on the controllers currently displayed on the screen.
3-3. Current FCS Button 
Searches the fault codes again based on the controllers selected when first entering the function.
Since the search criteria differ from the Rescan button, you can use them according to your specific purpose. You can also select past records using the dropdown list.
