VCFRONT_a511_DCDCSaturationLoadShed
Description
Electrical current flowing through the power conversion system (PCS) eFuse is approaching the DCDC converter's maximum handling capacity. The front vehicle controller (VCFRONT) is shedding some vehicle electrical loads by cutting power to less essential electronic control units (ECUs).
Condition
The PCS eFuse current value is within 20A of the DCDC converter's maximum handling capacity for 5 seconds.
Clear Condition
The PCS eFuse current value remains lower than the DCDC converter's maximum handling capacity long enough for VCFRONT to stop loadshedding (until DCDC Saturation Loadshed Stage is MIN).
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).
