OBDII.DTC

CI OBDII.DTC

OBDII.DTC is a .NET Standard library of categorized On-board Diagnostics II (OBDII) Diagnostic Trouble Codes (DTCs), with code descriptions. It covers the generic codes defined in the ISO[^1] and SAE[^2] standards, along with a limited set of manufacturer-specific codes. Additional manufacturer codes are welcome as contributions. Manufacturer-specific codes share number ranges across manufacturers, so their descriptions may only be accurate for some vehicles. DTCs are categorised as Powertrain (P codes), Chassis (C codes), Body (B codes), or Network Communication (U codes). Each code has a hex value based on its category as defined in ISO[^1] and SAE[^2] standards, Powertrain (0x0000 - 0x3FFF), Chassis (0x4000 - 0x7FFF), Body (0x8000 - 0xBFFF), Network Communication (0xC000 - 0xFFFF).

[^1]: ISO 15031 [^2]: SAE J2012

Features

  • Enumerated DTCs with thousands of codes.
  • Extension methods DTC.GetDescription() and DTC.GetCategory() to fetch the description and the category of a particular DTC.
  • Manufacturer-specific descriptions and code checks.

Installation

Install this package from nuget:

dotnet add package OBDII.DTC

Usage

After installing the package, the DTC enum can be used to reference the trouble codes. For example:

DTC code = DTC.P0100;
Console.WriteLine(code.GetDescription()); // Outputs: "Mass or Volume Air Flow Sensor A Circuit Range/Performance"
Console.WriteLine(code.GetCategory()); // Outputs: "Powertrain"

Manufacturer-specific descriptions and code checks:

DTC code = DTC.P134B;
Console.WriteLine(code.GetDescription(Manufacturers.Honda)); // Outputs: "Crankshaft Signal Diagnose"
Console.WriteLine(code.IsManufacturerCode()); // Outputs: True
Console.WriteLine(code.IsManufacturerCode(Manufacturers.Honda)); // Outputs: True

Development

The library and NUnit tests are in src/OBDII.DTC and src/OBDII.DTC.Test. Run the tests with the .NET 10 SDK:

dotnet test src/OBDII.DTC.sln --configuration Release

If any codes are incorrect or missing, contributions are greatly appreciated to help improve this library.
