C1380F8 — High-voltage voltage converter - above voltage limit (48 V)

High-voltage voltage converter - above voltage limit (48 V). The Taycan report this code; below is which control unit sets it on each model and how to read and clear it.

Which models and control units set C1380F8

Porsche Taycan

How to read and clear C1380F8

  1. Plug a standard ENET (Ethernet-to-OBD) cable into your Porsche's OBD port and your Mac or Windows PC.
  2. Open STEUER14, pick your car and run a fault scan: every control unit is read, and C1380F8 shows with its status, its full description and the freeze frame when the unit stores one.
  3. Fix the cause first, then clear the fault memory and scan again to check it stays away. Reading and clearing fault codes is free on every control unit.

Fault names come from the manufacturer's diagnostic data. STEUER14 is independent and not affiliated with Porsche AG. A code tells you what a control unit detected, not always which part failed — check wiring, supply voltage and related codes before replacing parts. STEUER14 shows each fault's full description, status and freeze frame on the car.
