Importance of Professional Diagnosis
While DTCs provide valuable clues, it’s essential to remember they are not definitive diagnoses. A qualified mechanic should perform a thorough inspection, considering the DTC, vehicle symptoms, and other diagnostic data to accurately pinpoint the root cause of the problem. Relying solely on the DTC can lead to misdiagnosis and unnecessary repairs. Furthermore, some issues can trigger multiple codes, making it challenging to isolate the primary fault without expert knowledge and specialized equipment. A proper diagnosis is crucial for ensuring that the correct repairs are performed, saving both time and money in the long run.
