Volvo fault codes
199 distinct codes across 236 real diagnostics on Volvo, including the Volvo-specific ones no generic code list can decode.
Volvo-specific codes
These are manufacturer-specific, which means the same code on another marque is a different fault. That is exactly why they have no page of their own here and no entry in any generic code list: a single description for one of these would be wrong more often than right. Below they are scoped to Volvo, ranked by how often we have actually seen them, which is a claim we can stand behind.

To turn one of these into a cause you need the marque, the model and the engine, which is what the tool does. A code on its own is a starting point, not an answer.
Standard codes we see most on Volvo
These are standardised, so they mean the same thing on every vehicle and each one has a page of its own. The counts are what we see on Volvo specifically.

FAQ
Frequently asked questions
How do I run a diagnosis?
Select the vehicle on Start, click the Diagnostic card and choose New diagnostic. Fill in the description, the error codes and the mileage, then click Analyze.
Learn more: Diagnostic (vehicle-first start), Diagnostic form: description, error codes and mileage
Do I have to type the codes from my scan tool?
No. Click the camera button next to Error codes and take or choose a photo (JPEG or PNG) of the scan tool's screen; WrenchLane reads the codes and their descriptions into the form. You can also speak them with the microphone.
Learn more: OBD reader photo scan (fault codes from a photo), Voice input for the problem description
Are the public fault code pages built from my diagnostics?
They are built from anonymised, aggregated diagnostics run in WrenchLane; no workshop, customer or vehicle can be identified. Each fault code page shows how often the code was seen across those diagnostics and in how many separate workshops.
