Hybrid/EV Battery Pack F Over Temperature
The BMS detects that battery pack subsection F is operating above the safe temperature threshold. Cell-level cooling or pack thermal management is compromised on this section.
Affected components
- Hybrid battery pack f
- Battery thermal management
Common causes
- High likelihood: Coolant flow to this section reduced
- Medium likelihood: Cell imbalance causes local heating
- Low likelihood: Ground point with elevated resistance
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
