VCFRONT_a264_iBoosterVoltageMismatch
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).
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.
