Keep both records together. One controller’s warning may accompany a problem recorded elsewhere, but the relationship needs diagnosis. A battery message should not distract from documented engine symptoms or lead to replacing the battery without supporting findings.
What to tell us
- Engine symptoms.
- Full scan.
- Order of warnings.
Before arranging work
The engine remains an important part of hybrid diagnosis. Keep its running symptoms and maintenance history alongside the hybrid report. A system warning is a starting point for investigation, not a parts list or proof that the traction battery is faulty.
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.
