Impact

The coolant pumps and condenser fan will be unavailable. As a result, the power conversion system (PCS) temperature may exceed normal operational range. HVAC cabin cooling (air conditioning) and powertrain performance may be limited.

Description

The front vehicle controller (VCFRONT) fused high current eFuse circuit is open (tripped), interrupting low voltage (LV) power feed to the coolant pumps and condenser fan. HVAC cabin cooling (air conditioning) and powertrain performance may be limited.

Cause

VCFRONT detects the fused high current eFuse circuit is open (tripped).

Clear condition

VCFRONT no longer detects the fused high current eFuse circuit as open (tripped), or the vehicle enters a state where the eFuse is expected to be open (off).
