DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS operation.
This DTC is stored when the +BS terminal voltage deviates due to a malfunction in a power supply or charging system circuit such as the battery or alternator circuit, etc.
