Diagnostics and fault codes

Read fault codes in context

In diagnostics, distinguish codes previously stored in the app from a current reading of the vehicle’s control units. Connect to the car and run the available read operation. Keep the exact code and describe symptoms and circumstances: a warning light, noise or loss of power does not become a diagnosis simply because a DTC appears.

Standard OBD code reading is available in Free; clearing depends on recognised Full rights and vehicle support. Clearing does not repair the cause and may remove useful information. To learn more, look up the exact code in the website catalogue.
