GPF Regeneration
This procedures is to forcibly regenerate the GPF with scan tool when the GPF doesn't have been regenerated during driving. For example, if the vehicle has repeated "Low speed driving" or "Short distance driving", the GPF regeneration procedure cannot be proceeded because "Regeneration Mode" doesn't made.
