The BMS detects implausible cell module voltage readings during balancing or load test, indicating sense circuit drift or cell defect.
Affected components
- Bms
- Hv battery
Common causes
- High likelihood: Defective cell in module
- Medium likelihood: BMS sense circuit drift
- Low likelihood: Module software outdated, reflash may resolve
Diagnostic notes
