Understanding your car's language: OBD trouble codes

Ever wondered what those warning lights on your dashboard mean? They're often linked to OBD-II diagnostic trouble codes. Discover what these codes are and how Sparks-Auto-Diagnostics uses them to accurately diagnose and fix your vehicle's issues.

What are diagnostic trouble codes?

Most diagnostic codes have been standardised and are known as "OBD-II" (on-board-diagnostics). These codes are triggered when a fault is detected or a system is not working as it should be. The code is stored in the vehicle’s memory and can be accessed in a diagnostics test with specialised software. At Sparks-Auto-Diagnostics, we have the advanced tools and expertise to accurately read and interpret these codes.

The four main areas of fault codes

There are over 200 fault codes that may be generated, but they fall into four main categories. Understanding these helps us pinpoint the problem quickly and efficiently:

  • Body codes, prefixed with a B: This covers things inside the passenger compartment, such as airbags, air conditioning, passenger comfort and safety, and driver assistance.
  • Chassis codes, prefixed with a C: This refers to most of the mechanical systems, including suspension, braking and steering.
  • Powertrain codes, prefixed with a P: This refers to the engine components, transmission and drivetrain parts.
  • Vehicle network codes, prefixed with a U: This includes the wiring and other vehicle integration systems such as the computers and sensors.
