Convertible-Top Module (CVM II)

The convertible-top module (CVM II) is installed in the left rear quarter panel behind the inte-
rior trim panel. It contains the processing, controlling and monitoring electronics for the
complete top operation. The CVM II communicates with the GM over the K-Bus for opera-
tion of the top storage cover and windows.

Operation of the hydraulic cylinders is controlled via final stages and solenoids mounted on
the hydraulic unit and top frame.

The CVM is fully diagnoseable and contains a fault memory for storage of monitored faults.
Diagnosis is carried out over the K-Bus with the DIS or MoDiC.
