   • Loss of Diagnostic Data: Clearing codes also erases freeze frame data, which captures the conditions under which the DTC was triggered. This can make diagnosing intermittent issues more challenging.
   • Emission Readiness Monitors: Clearing codes resets the emission readiness monitors. The vehicle will need to be driven through a specific drive cycle to reset these monitors, which may be required for emissions testing.
   • Potential for Misdiagnosis: Clearing codes without addressing the underlying problem can lead to misdiagnosis and further damage to the vehicle.
3. When to Clear Codes:
   • After Repair: Clear the codes after you have successfully diagnosed and repaired the issue.
   • Verification: Clear the codes to see if they reappear, which helps confirm whether the repair was effective.
   • Temporary Issues: If a code was triggered by a temporary issue (e.g., a loose gas cap), clearing the code may be appropriate once the issue is resolved.
4. When Not to Clear Codes:
   • Before Diagnosis: Do not clear codes before you have had a chance to properly diagnose the issue.
   • Unresolved Issues: Do not clear codes if you are aware that the underlying problem has not been addressed.
5. Follow-Up Steps:
   • After clearing codes, monitor the vehicle for any recurring issues.
   • Perform a test drive to ensure the vehicle is functioning properly.
   • If the check engine light reappears, re-scan the vehicle to identify any new DTCs.
