De åtta moduldokumenten och exempelflödet får engelska versioner. Kataloger och filnamn följer med: moduler/ → modules/, exempel/ → examples/, och de svenska filnamnen ersätts av engelska. Ett engelskt dokument i moduler/arendebrief.md hade varit inkonsekvent. Bytet gjordes med git mv så historiken följer med, och interna länkar i de svenska versionerna pekar nu på svenska syskon i stället för på filnamn som inte längre finns. Kodidentifierare och JSON-exempel står oöversatta även i de engelska versionerna — falt, hemlig, uppslag och svarsfalt är fältnamn i integrationer.json, inte prosa.

# Worked example: "The car vibrates at around 88 km/h"
|
|
|
|
> Canonical version. Swedish: [vibration-at-88-km-h.sv.md](vibration-at-88-km-h.sv.md).
|
|
|
|
This example illustrates how Guidad Felsökning works in practice: a digital
|
|
diagnostic process, not a chat. The system does not jump straight to "it's
|
|
probably wheel balancing" — it follows a reproducible method.

|
## The case
|
|
|
|
**Customer's description**
|
|
|
|
> "The car vibrates at around 88 km/h."
|
|
|
|
---
|
|
|
|
## Step 1 — Verify the symptom
|
|
|
|
The system asks:
|
|
|
|
- Is the vibration speed-dependent?
|
|
- Is it felt in the steering wheel, the seat, or the whole car?
|
|
- Does it occur under acceleration, at steady speed, or under braking?
|
|
- Does it disappear above or below a particular speed range?
|
|
|
|
Once the answers are documented, the process moves on.
|
|
|
|

|
|
|
|
## Step 2 — Visual check
|
|
|
|
The system asks the technician to photograph:
|
|
|
|
- The left front wheel
|
|
- The right front wheel
|
|
- The left rear wheel
|
|
- The right rear wheel
|
|
|
|
The image analysis can then help identify things that are genuinely observable,
|
|
for example:
|
|
|
|
- the tyre's DOT/manufacturing date (via OCR),
|
|
- unusual or uneven wear,
|
|
- visible damage or deformation,
|
|
- missing or loose balance weights, if clearly visible,
|
|
- an incorrect tyre size or mismatched tyre types.
|
|
|
|
What matters is that the system distinguishes **observation** from
|
|
**conclusion**. For instance it may say:
|
|
|
|
> "A balance weight appears to be missing on the right front wheel. Check the
|
|
> wheel manually."
|
|
|
|
rather than asserting that this is the cause of the fault.
|
|
|
|

|
|
|
|
## Step 3 — Recommended checks
|
|
|
|
The system then proposes the next steps, for example:
|
|
|
|
- check tyre pressure,
|
|
- check wheel torque,
|
|
- check radial and lateral runout,
|
|
- check wheel balancing,
|
|
- check bushings and joints,
|
|
- carry out a road test.
|
|
|
|
Each item is ticked off and documented.
|
|
|
|
---
|
|
|
|
## Step 4 — Road test
|
|
|
|
The system summarises what is to be verified during the road test:
|
|
|
|
- The speed at which the vibration occurs.
|
|
- Any change under acceleration.
|
|
- Any change under engine braking.
|
|
- Any change when cornering.
|
|
- Whether the vibration is felt in the steering wheel or the body.
|
|
|
|

|
|
|
|
## Step 5 — Summary
|
|
|
|
When the technician chooses to pause or finish the work, a report is generated
|
|
automatically, for example:
|
|
|
|
**Checks performed**
|
|
|
|
- Four wheels photographed.
|
|
- DOT codes documented.
|
|
- Tyre wear checked.
|
|
- Tyre pressure verified.
|
|
- Wheel balancing checked.
|
|
- Road test carried out.
|
|
|
|
**Result**
|
|
|
|
Observations and measured values are summarised without the system drawing
|
|
conclusions that lack support.
|
|
|
|
**Recommended next steps**
|
|
|
|
For example checking the driveshafts, wheel bearings or other components if the
|
|
earlier checks have not identified the cause.
