VCFRONT_a508 — Bridge eFuse Load Shed

Full alert identifier: VCFRONT_a508_bridgeEFuseLoadShed

Alert description

Electrical current flowing through the Bridge eFuse has equaled or exceeded 120A. The Bridge 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 Bridge eFuse current value equals or exceeds 120A for 100 milliseconds.

Clear condition

The Bridge eFuse current value remains below 120A long enough for VCFRONT to stop loadshedding (until Bridge eFuse Loadshed Stage is MIN).
