Top Raising Sequence
WARNING: This page is about a different car, the 2003 BMW Z8, 2002 BMW Z8, 2001 BMW Z8, and 2000 BMW Z8. However, it is still accessible from the selected car via links, so may be relevant.
With top switch pressed "closed":
- The CVM activates the latching drive motor, which releases and opens the latches.
- The latch hall sensor confirms the release of the latches by sending a signal to the CVM.
- The CVM activates the pump motor relay and the hydraulic pump runs in the reverse direction, pressurizing the hydraulic cylinders to raise the soft top frame.
- The soft top is raised to the point that the top-up hall sensor signals the CVM to stop the pump motor.
- At this point the soft top is slightly open, the driver must reach into the recessed handle and squeeze and pull down at the same time.
- The pull handle hall sensor will trigger the CVM to activate the latching drive motor to lock the top frame/bow to the windshield frame.
