VCFRONT_a483 — Lv Bridge Voltage Mismatch
Full alert identifier: VCFRONT_a483_lvBridgeVoltageMismatch
Alert description
The vehicle controller detects there is voltage mismatch greater than 0.5V between the input power to the front vehicle controller (VCFRONT) and low voltage (LV) bridge circuit.
Potential impact
Vehicle functions that depend on the LV bridge may be unavailable, or their performance may be affected.
Set condition
The voltage mismatch is greater than 0.5V between the VCFRONT printed circuit board assembly (PCBA) input voltage and the eFuse output voltage.
Clear condition
The voltage mismatch is less than 0.5V between the VCFRONT printed circuit board assembly (PCBA) input voltage and the eFuse output voltage.
