• The ABS HU/CM, integrating both the hydraulic unit (HU) and control module (CM), has been adopted,
resulting in size and weight reduction.
• A semi-conductor element type front ABS wheel-speed sensor has been adopted, improving reliability and
reducing size and weight.
• A magnetic encoder type front ABS sensor rotor that is integrated with the wheel hub component has been
adopted, improving reliability and reducing size and weight.
• Electronic brakeforce distribution (EBD) control has been adopted, resulting in improved safety and handling
stability.
