VCFRONT_a264 — iBooster Voltage Mismatch
Full alert identifier: VCFRONT_a264_iBoosterVoltageMismatch
Alert description
The front vehicle controller (VCFRONT) detects there is voltage mismatch greater than 0.5V between the input power to the VCFRONT and the braking assist circuit for the iBooster (IBST) electronic control unit (ECU).
Potential impact
Vehicle functions that rely on the iBooster 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.
