DTC
Diagnostic Trouble Codes (DTCs) are stored in your vehicle’s Powertrain Control Module (PCM) when a performance issue is detected. These codes provide detailed information about the faulty component or system, helping technicians accurately diagnose and repair the vehicle. During a diagnostic check, the PCM communicates DTCs to an external code reader for interpretation.
Benefits of DTC
Identifies and Reports Issues
Diagnostic Trouble Codes (DTCs) enable the car's computer to detect and report any problems that arise while the vehicle is running, ensuring timely identification of issues.
Speeds Up Diagnosis and Repair
The DTC system allows mechanics to quickly diagnose and troubleshoot problems, reducing the time needed to service the car and get it back on the road.
Stores Codes for Future Diagnosis
DTCs are often stored, so even if an issue isn’t immediately apparent, mechanics can still identify and repair the problem later, ensuring nothing is overlooked.
Reduces Servicing Costs
By alerting mechanics to potential problems early, DTCs help prevent minor issues from escalating into costly repairs, saving money on vehicle maintenance.
Provides Early Warnings to Drivers
DTCs can alert drivers when their vehicle is at risk, allowing them to address issues promptly and avoid expensive repairs, maximizing the car’s lifespan.
