Pro plan

Turn solved faults into your garage's private knowledge

Record the symptoms, tests, root cause and repair while the job is fresh, then search your company's library when a similar vehicle comes back. Diagnostic Library is included with the Pro plan.

Find the last fix
Search by fault code, engine, vehicle or symptom instead of relying on who remembers the job.
Keep the proof with the repair
Save the tests, confirmed cause, work carried out and final verification as one useful case.
Private to your company
Your diagnostic cases stay inside your company and follow the access set for each team role.

Build knowledge as the work happens

Three steps from a difficult fault to something the whole garage can use next time.

  1. Record the case while it is fresh

    Start from a stored vehicle or enter the vehicle details manually. Add the reported fault, symptoms, codes, observations and the tests you carried out, without waiting until the end of the job to reconstruct it.

  2. Close the loop with evidence

    Record the confirmed root cause, link the evidence that proves it, list the repair actions and note how the original fault was checked after the work. The case becomes a useful answer, not just another fault-code note.
