Fault Memory
The fault memory of the CVM is stored in an NVRAM which can store up to a maximum of
16 faults. The fault are stored in the order of occurrence and a distinction is made between
permanent and sporadic faults.
Operation in the Event of Faults
If a fault occurs during raising or lowering the top, all movement will cease and the fault will
be stored in the fault memory. The emergency closing procedure must be used to close the
top and the vehicle taken to the dealership for repair.
Depending on the location and type of fault, it may be possible to raise or lower the top fully
by pressing the switch in the opposite direction from which the fault occurred.
If the top switch is held > 20 seconds after completing a raising/lowering procedure, a fault
will set in the CVM. The control module assumes a fault to ground in the switch or lead. The
ignition switch must be cycled to clear the fault before the top will again function. The fault
will remain in the module until cleared with the Tester or MoDiC.
All sequenced movements of the top have time out limits set in the control module. If a time
out occurs before the end position is reached, the specific movement will be switched off
to prevent damage to any of the top components.
