WysokiHV Battery Management System Malfunction
OBD-II (EN): High Voltage Battery Management System Fault
Code P0F15 concerns the high-voltage system in hybrid and electric vehicles - most often indicates a problem with the traction battery management module or the cells themselves. Causes can vary: from sensor faults, through wiring issues, to natural battery pack wear. Due to the risks associated with the high-voltage system, diagnosis and repair should be entrusted exclusively to an authorized service center with HV qualifications.
Symptoms
Check Engine Light (MIL) illuminated. Vehicle power limitation or limp mode. Reduced electric range. Hybrid or electric system warning. Possible traction battery charging issues. Sudden change in vehicle behavior during acceleration.
Possible causes
• Faulty or defective battery management module (BMS/HV Battery Control Module) • Defective high-voltage battery cell temperature sensor • Wear or mechanical damage to traction battery cells • Open or short circuit in high-voltage system wiring • Faulty DC/DC converter or electric drive inverter • Contamination or corrosion of high-voltage circuit connectors
