VCFRONT_a509 — Vcright eFuse Load Shed

Full alert identifier: VCFRONT_a509_vcrightEFuseLoadShed

Alert description

Electrical current flowing through the right vehicle controller (VCRIGHT) eFuse has equaled or exceeded 100A. The VCRIGHT eFuse circuit may open (trip) if low voltage (LV) electrical system loads are not reduced. The front vehicle controller (VCFRONT) is shedding some vehicle electrical loads by cutting power to less essential electronic control units (ECUs).

Potential impact

Some convenience features will be unavailable as VCFRONT limits LV electrical system current draw by cutting power to some electronic control units (ECUs).

Set condition

The VCRIGHT eFuse current value equals or exceeds 100A for 100 milliseconds.

Clear condition

The VCRIGHT eFuse current value remains below 100A for 100 milliseconds.
