Each DTC consists of five characters: a letter followed by four digits. Here’s a breakdown of what each character represents:

First Character (Letter): Indicates the system where the fault occurred.
- P: Powertrain (engine and transmission)
- B: Body (airbags, climate control, etc.)
- C: Chassis (brakes, steering, suspension)
- U: Network (communication systems)
Second Character (Digit): Specifies whether the code is generic or manufacturer-specific.
- 0: Generic (defined by the Society of Automotive Engineers – SAE)
- 1: Manufacturer-specific
Third Character (Digit): Identifies the subsystem involved. For example:
- 1: Fuel and air metering
- 3: Ignition system
- 7: Transmission
Fourth and Fifth Characters (Digits): Provide a specific fault designation.

Example: The code P0301 breaks down as follows:

P: Powertrain
0: Generic code
3: Ignition system or misfire
01: Cylinder 1 misfire detected
