VCFRONT_a265 — ESP Voltage Mismatch
Full alert identifier: VCFRONT_a265_ESPVoltageMismatch
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 the stability controller circuit for the Electronic Stability Program (ESP) electronic control unit (ECU).
Potential impact
Vehicle functions that rely on the ESP may be limited or may not function as expected.
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.
