VCBATT1_a482 — Lv Bridge eFuse Trip
Full alert identifier: VCBATT1_a482_lvBridgeEFuseTrip
Alert description
The battery vehicle controller (VCBATT) has opened the voltage supply circuit to the Low Voltage (LV) bridge, making the low voltage (LV) battery no longer supported by the Power Conversion System (PCS). If the PCS is no longer providing support to VCBATT, functions on the right side of the vehicle will be unavailable.
Potential impact
The LV battery is no longer supported by the power conversion system (PCS). If the PCS is no longer providing support to the front vehicle controller (VCBATT), functions on the right side of the vehicle will be inoperable or unavailable, because the front vehicle controller (VCFRONT) will no longer be powered by VCBATT.
Set condition
A condition causing the voltage supply to the LV Bridge to be interrupted is reported by the LV bridge eFuse circuitry.
Clear condition
A condition causing the voltage supply to the LV bridge to be interrupted is no longer reported by the LV bridge eFuse circuitry.
