Ask which evidence supports the inspection and which area will be assessed. Communication codes alone may not identify the physical location of the problem. Clear scope helps distinguish targeted diagnosis from unexplained module replacement.
What to tell us
- Affected systems.
- Proposed inspection area.
- Recorded evidence.
Before arranging work
Communication diagnosis needs the complete report, affected functions and operating state. A missing response can have several explanations. Do not bridge network wiring or repeatedly disconnect controllers as an owner-level experiment.
Ask AXION about this fault. Send the vehicle details and the information above. Please agree an appointment or postal assessment with us before travelling or sending a module.
