4.2 Clearing Diagnostic Trouble Codes (DTCs)
This function erases DTCs from the vehicle's computer and turns off the Check Engine Light (MIL). Note: Clearing codes does not fix the underlying problem. The issue must be repaired to prevent the codes from reappearing.
- After reading codes, select "Erase Codes" from the menu.
- Confirm the action when prompted.
- The scanner will indicate if the codes have been successfully cleared.
4.3 I/M Readiness Status (Smog Check)
The I/M Readiness function checks the status of the vehicle's emission-related monitoring systems to determine if they are ready for an inspection/maintenance test.
- From the main menu, select "I/M Readiness" or press the I/M button.
- The scanner will display the status of various monitors (e.g., O2 Sensor, EVAP System, Catalyst Monitor) as either "OK" (complete), "INC" (incomplete), or "N/A" (not applicable).
- The LED indicators on the device also provide a quick visual reference:
- Green LED: All monitors are running and performing their diagnostic tests.
- Yellow LED: Some monitors are not yet ready.
- Red LED: One or more monitors have failed their diagnostic tests, or there are pending/permanent DTCs.
