  • Reduced range for electric vehicles/hybrids

Causes

  • Abnormally low ambient temperature (below -25...-30°C)
  • Malfunction of the temperature sensor in the BMM module
  • Open or short circuit in the temperature sensor circuit
  • Malfunction of the battery monitoring module itself
  • Insufficient heating of the battery system after a long stay in the cold

How to Fix

  1. Check the actual ambient and battery temperatures using a scanner
  2. If the temperature is objectively low, warm up the car and check that the error disappears
  3. Check the BMM temperature sensor circuit for an open or short circuit.
  4. Check BMM temperature sensor data in real time using scanner
  5. If a sensor malfunction is confirmed, replace the BMM module
  6. Make sure the battery heating system (if equipped) is working correctly
