Understanding Diagnostic Trouble Codes (DTCs)
DTCs are alphanumeric codes that represent specific malfunctions detected by your car’s computer. They follow a standardized format:
- First Character: Indicates the system where the fault occurred (e.g., “P” for Powertrain, “B” for Body, “C” for Chassis, “U” for Network).
- Second Character: Specifies whether the code is generic (“0”) or manufacturer-specific (“1”).
- Third Character: Identifies the specific system or subsystem related to the fault (e.g., “1” for Fuel and Air Metering, “2” for Fuel and Air Metering (Injector Circuit), “3” for Ignition System or Misfire).
- Fourth and Fifth Characters: Pinpoint the specific problem within the identified system.
