Diagnostic Trouble Codes


Dear Valued Customer,

Some of our reports contain Diagnostic Trouble Codes (DTCs), also known as Fault Codes, which have been extracted directly from your vehicle's electronic control units and modules.

These codes should not be interpreted literally as a direct indication of which parts need to be replaced. While replacing a component may occasionally resolve an issue, more often, the problem may not be as simple as changing out a single part.

Numerous factors can trigger DTCs, including wiring issues, module malfunctions, or mechanical failures that may not be directly related to the specific DTC displayed.

We strongly advise against replacing parts solely based on DTCs. Doing so could lead to unnecessary expenses for parts and labor without resolving the underlying problem.

Instead, we recommend having a thorough diagnostic procedure performed by a qualified professional to accurately identify the root cause(s) of the issue. Please refer to the Guidelines document for more information.

If you have any questions or concerns regarding the information above, please don't hesitate to reach out.
