Mercedes-Benz S-Class — 电动转向
S-Class EPS with Active Curve System
W222/W223 S-Class uses EPS combined with the ACTIVE CURVE SYSTEM — a hydraulic active anti-roll bar actuated by an electrohydraulic unit. Faults in this system cause: heavy steering at low speed, body roll warning on the instrument cluster, and occasional suspension-related fault codes. XENTRY is the only tool that can access and code the ACTIVE CURVE ECU.
