Alternator protection
- Defect
- Affected vehicles may have been assembled with contact or with a reduced clearance between the Gasoline Particulate Filter pipe and the pole protection cap of the 48V Belt Starter Generator. There is a possibility of contact between these components leading to water infiltration and an electrical arch which could trigger a thermal event.
- Remedy
- Replace the pole protection cap of the 48V Belt Starter Generator. Check the distance between the Gasoline Particulate Filter pipe and the pole protection cap of the 48V Belt Starter Generator and re‑position or replace the pipe if required.
