Full alert identifier: VCFRONT_a509_vcrightEFuseLoadShed
Alert description
The right vehicle controller (VCRIGHT) EFuse current has reached 100A and may trip the EFuse if low voltage electrical system (LV system) loads are not reduced. The vehicle's LV system needs to shed electrical loads by cutting power to some electronic control units (ECUs).
Potential impact
Some convenience features will be unavailable as the vehicle's low voltage electrical system (LV system) limits current draw by cutting power to some electronic control units (ECUs).
Set condition
The right vehicle controller (VCRIGHT) EFuse current is measured as greater than 100A for 100ms.
Clear condition
The right vehicle controller (VCRIGHT) EFuse current is measured as less than 100A.
