Diagnostic trouble codes also referred to as engine fault codes, are five-digit codes that showcase certain problems and issues with the vehicle. These codes can be seen by using a scanning tool where codes are displayed after the tool scans the OBD (On-Board Diagnostics) system. These five-digit codes usually contain one letter and four numbers, an example being D-4532.
The first number in the DTC lets you know specific vehicle manufacturer codes or an SAE generic code that applies to all OBD II systems. The last three numbers provide information regarding the specific vehicle circuit and sub-category.
The scanned trouble codes can be retrieved by the telematics device and forwarded to the fleet management company. Here they undergo a detailed inspection to determine what the issue is and how it can be solved. This can range anywhere from minor issues such as exhaust gas temperature sensor failure to ignition problems and much more. Major issues such as fuel injectors, ignition timing or brake pad wear pose a greater threat to vehicle function.
Fleet management after receiving fault codes can suggest where and what kind of fix is required. Or if it is likely the car is on its last journey and a total engine refurb is needed.
It is primarily beneficial for the owners of vehicles because timely indication of the problem helps them find a fast solution. Saving them from any major accidents as well as long trips to the mechanic reduces fleet numbers and costs businesses time and money.
