Check wiring too or replace the VSS (vehicle speed sensor) located on the transmission.
In the event of an ECU or hydraulic failure, the system will fail safe to a locked bars condition. The locked bars condition will allow the torsion bars to operate in a similar manner as conventional passive anti-roll bars. Prolonged cornering forces will allow a progressive increase in roll angle due to hydraulic leakage through the actuators and valve block. Failures will be relayed to the driver by the illumination of the ACE warning lamp in the instrument pack. Faults are recorded by the ECU and can be retrieved using TestBook.
When the ignition switch is moved to position II, the warning lamp will illuminate for two seconds to check functionality. The warning lamp functionality can also be checked using TestBook.
TestBook must also be used to perform a bleeding procedure after maintenance operations have been performed to ensure that complete system bleeding is performed. Trapped air in the system can seriously reduce the system performance.
