07421 186 356**Reason to Call:** We provide **on-site diagnosis** in SE13 using dedicated Kia/Hyundai software to confirm if the **DC-DC Converter** or **ICCU** is the source of your 12V drain.
The DC-DC converter is part of the ICCU, charging the crucial 12V system from the HV battery. Failure means a dead car:
- **Non-Starting Vehicle:** The most common symptom; the 12V battery rapidly discharges because the DC-DC converter has failed to charge it.
- **Check Electric Vehicle System:** This warning can be triggered by ICCU/DC-DC communication errors.
- **Integrated Charging Control Unit (ICCU) Faults:** The module housing the DC-DC converter and On-Board Charger (OBC) has failed internally.
- **12V Battery Drain:** Persistent, rapid drain even after the 12V battery has been replaced.
