TECHNICAL SERVICE OPERATIONS MAS003644 RU 23-35 RAPID UPDATE FROM: Maserati TSO TO: Maserati Network Rapid Update 646 MC20 & MC20 Cielo – Check side mirrors DATE: JULY 24 2023 Certain Maserati MC20 and MC20 Cielo (M240) MY23 listed in MODISCS+ are involved in a Rapid Update to verify the integrity of the wiring of the external side mirrors. Due to an assembly problem, it is possible that on some cars the internal wiring to the external rearview mirror may have been pinched. In the long run, this can lead to deterioration of the wiring and lead to malfunctions in the mirror movement system. We remind you that all the Rapid Updates must be performed within the first workshop visit, regardless of the Mandatory setting set in Modis, as required by Maserati policies. Also, for vehicles in Stock Dealer / PDI, it is necessary to carry out all action operations before delivery to the end customer, as required by the White Book and explicitly reported in the Pre-delivery checklist. Please read and review this bulletin first before starting the procedure. Contact your Regional AfterSales Manager (RAM) or the Technical Support Helpdesk if you have any questions.
