All Known Issues

12V DC-DC Converter & PDM Faults

SeriousElectrics & Electronics

The Power Delivery Module (PDM) houses the DC-DC converter. If it fails, the 12V battery won't charge from the traction battery, leading to random CAN-bus errors or the car refusing to move.

Est. Repair Cost: £800–£2,000
Warning Signs:

Random "Ghost" errors on dash, Car won't shift out of Park, 12V battery dies even after replacement

What to Inspect:
  • Check 12V charging voltage while car is in "Ready" mode (should be 13V+)
  • Check if AC charging works (PDM failure often kills AC but not DC charging)

Buying Tips for 2014–2017 Nissan Leaf (ZE0)

  • ✓Check battery health bars; pre-2013 cars have more vulnerable chemistry than later "Lizard" or 30kWh packs.
  • ✓Verify if the car has a Heat Pump (2014+ Acenta/Tekna); this is vital for UK winter range compared to the older resistive heater.
  • ✓A healthy 12V battery matters more than many buyers realise because low voltage creates bizarre "Service EV System" faults.
  • ✓Listen for front driveshaft clicking and confirm the charging flap opens and latches cleanly.
