- U (Network): Communication between electronic control units (ECUs).
-
Understanding the Structure of a DTC:
- The first character indicates the system (P, B, C, or U).
- The second character indicates whether the code is generic (0) or manufacturer-specific (1).
- The third character indicates the subsystem (e.g., fuel system, ignition system).
- The last two characters indicate the specific fault.
-
Example DTC: P0301
- P: Powertrain
- 0: Generic code
- 3: Ignition system or misfire
- 01: Cylinder 1 misfire
-
Steps to Interpret a DTC:
- Read the DTC using your scan OBD2 software.
