The process involves verifying that all related systems are functioning as designed. If any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present, they will be recorded and addressed before proceeding with the TSB's repair. If the customer's reported symptom matches the description in the bulletin, the repair procedure can be initiated.
