D If the accumulator pressure drops abnormally to a level below the pressure set at the ECU, the skid
control ECU illuminates the brake system warning light, the ECB* warning light, ABS warning
light and the master warning light. Then, a warning message appears on the multi-information
display in the combination meter, and the VSC warning buzzer sounds to alert the driver of the
abnormal hydraulic pressure.
