Operation In The Event Of A Roof Fault

Operation in the event of a roof fault is a function that makes roof operation (opening, closing and load assistance) possible even if certain sensors signal faults.

The function can only be activated when CAN communication with the Convertible Roof Module (CRM) works. Other requirements for roof operation, such as temperature in the hydraulic pump, supply voltage and the vehicle's speed still apply.

In the event of operating the roof with a non-functioning sensor, a warning sound signal is sounds from the Driver information module (DIM) and a text message is displayed. If the operating button is then released and pressed again within 5 minutes, the roof continues to operate, after 2 seconds, at the same time as the audible signal sounds. If roof operation, in the event of a roof fault, temporarily stops, keep the button depressed so that the roof continues its operation. If the load assistance function is used in the event of roof fault operation, the roof sections can only be lowered.
