Timeline

The timeline is a chronological log of everything that happens during a fault investigation. It's the running diary of a diagnosis — notes you wrote, DTC codes you added or cleared, measurements you recorded, photos you took along the way and ultimately the resolution.

Adding a timeline entry

From any fault case page, tap the chat bubble button in the bottom-right corner to scroll to the timeline. Tap Add Entry and you'll see a form to add a new entry.

Entry types

Note

A freeform text entry. Use this for anything: what you tried, what you read, what the mechanic said, what changed after a repair.

DTC added / DTC removed

Tracks changes to the DTC codes on the case. When you add a new fault code to the case, a "DTC added" entry is automatically recorded. When you clear one, "DTC removed" is logged. This gives you a history of which codes came and went during the investigation.

Metadata

Key-value pairs for structured data — sensor readings, measurement values, part numbers, anything you'd put in a table. For example:

Resolution entry

Automatically created when you resolve the case. Contains your resolution description, the resolution type, and which DTC codes were cleared by the fix.

Replies

Each timeline entry can have related replies, tap the Reply option to add a reply. This is where community discussion happens, if you've allowed third-party timeline entries, other users can reply with suggestions or similar experiences.

Starring entries

If a timeline entry is particularly useful or insightful you can star it. Starred entries are counted and shown in the dashboard's "Most starred cases" list, star counts act as a guide to other users that a comment or suggestion was accurate or useful.

Editing entries

Tap the edit icon on any of your own entries to update the text or metadata. You can't edit entries made by other users.

Deleting entries

You can delete your own entries from the edit menu. Entries with replies can still be deleted, the replies remain but the parent entry is removed.

Community entries

If you've enabled Getting Help on a case, other FaultNet users can add entries and replies to your case. This is how community-sourced diagnosis works, others who've seen the same fault can share what fixed theirs.

You can toggle this setting on or off from the case edit page at any time.
