🔍 Common Causes of a Hybrid Battery Warning Light
When the “Check Hybrid System” or battery light appears, it could indicate:
🔋 1. Battery Degradation
Gradual wear over time causes reduced cell performance and triggers the warning.
⚠️ 2. Cell Voltage Imbalance
If one or more modules are out of sync, it causes stress on the system and throws a fault.
🧠 3. Battery Management System (BMS) Fault
A malfunction in the BMS can misread values or fail to control charge/discharge properly.
🧰 4. Cooling Fan Failure
Overheating the hybrid battery due to blocked or failed fans can set off the warning light.
🔌 5. Sensor or Wiring Issues
Damaged connectors or corroded wires in the HV battery harness can cause false alerts or real power delivery faults.
🚫 6. Inverter or System Integration Faults
Even if the battery is okay, other hybrid components (like the inverter) can generate battery-related warning codes.
