CVM5

Signal Sequence
The center console switch cluster SZM recognizes the switch position Open convertible top and this information is sent via the KCAN to the CVM 5.Following a safety enquiry performed by the CAS2, the CVM 5 activates the power window motors via the front door modules and KBM. The motors lower the 4 side windows a little. The rear window motor completely lowers the rear window (activated by CVM 5).

The CVM 5 then drives the electric motor in the front brace. This motor releases the catch hooks at the cowl panel and slightly raises the front brace.

The CVM 5 now activates the hydraulic module. First, the fins and front brace are raised. The convertible top compartment lid is then released and opened. When the Hall sensor on the cylinder for the convertible top compartment lid signals the convertible top compartment lid up status, the CVM 5 switches over the pump in the hydraulic module (hydraulic pump turns in other direction) and the convertible top is folded by means of the main pillar cylinders into the convertible top compartment.

When the angle of rotation sensors on the convertible top frame signal to the CVM 5 that the convertible top is positioned in the convertible top compartment, the change over valve for driving the cylinders of the convertible top compartment lid is switched off and the convertible top compartment lid is closed by means of the cylinders. The convertible top compartment lid is locked by means of a cable assembly from the kinematics box to the main bearing. The Hall sensor on the left hand kinematics box signals to the CVM 5 that the convertible top compartment lid is closed and locked. The CVM 5 and KBM send a signal indicating that all 5 windows are now closed.
