Re: Is there a fuse for the orthopaedic seat pump?

From whence did you get the knowledge?
My familiarity with pumps of this kind stems from my own encounters with the CL 500 (C215) model, whereby a pump was used for both the central locking mechanism and the lumbar support adjustments of the seats. The functionality of the central locking system was operational, however the seat adjustment mechanism exhibited a lack of functionality. The cause of the issue was a malfunctioning Y-joint located under the seats, each weighing around 50 kg and proving to be rather challenging to remove from the passenger compartment. The pump operates for a brief duration before initiating a timeout mechanism, which serves to safeguard against potential overheating. Upon attempting to modify the lumbar support, an audible indication of the pump's operation was discernible for a brief duration; nevertheless, no discernible alteration in the support was seen.
In the event of intending to remove the seats, it is essential to disconnect the battery and observe a minimum waiting period of 30 minutes, particularly if the seats are equipped with AirBags. The removal of seats in a vehicle has a potential danger of triggering the AirBag system. Additionally, this action involves the disconnection of the Supplemental Restraint System (SRS), which, if performed while the car's ignition is on, will generate a Diagnostic Trouble Code (DTC) that requires clearance using a diagnostic instrument.
