Hybrid/EV Battery Discharge Circuit Performance
The HV battery discharge circuit performance is outside calibration. Discharge resistor or contactor fault.
Affected components
- Hv battery discharge circuit
- Discharge resistor
- Bms
Common causes
- High likelihood: Discharge resistor value drifted
- Medium likelihood: Discharge contactor aged
- Low likelihood: Pack cell imbalance approaching service threshold
Possible symptoms
- EV/hybrid system warning light on
- Reduced power output or limp mode
- Charging may fail or be slowed
- Reduced electric range
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
