VCBATT1_a495 — LV Battery Recovery Blocked
Full alert identifier: VCBATT1_a495_LVBatteryRecoveryBlocked
Alert description
The vehicle controller detects a condition (or conditions) preventing the low voltage (LV) battery internal protection transistor (MOSFET) from closing so the LV battery can be recovered. However, the LV battery may be recoverable using an external LV Lithium Ion Battery charger tool.
Potential impact
The LV battery cannot be recovered while any condition blocking its internal protection transistor (MOSFET) from closing persists. The LV battery is unable to support vehicle electrical systems or to recharge via the power conversion system (PCS) until the internal protection MOSFET closes and recovery begins.
Set condition
A condition or combination of conditions prevents the LV battery internal protection transistor (MOSFET) from closing so the LV battery can be recovered. Alert log signal data should provide more information.
Clear condition
No condition is detected that prevents the LV battery internal protection transistor (MOSFET) from closing so the LV battery can be recovered.
