Granturismo – Brake Pad Sensor Connector

Check
DATE: OCTOBER 10 2023
Certain Maserati GranTurismo (189) MY24 listed in MODISCS+ are involved in a Rapid Update to

inspect the brake pad sensor connector.

This action is necessary because, in a limited number of vehicles, the brake pad sensor

connector weather seal and the protective cap may be absent. This issue has no impact on the

functionality of the braking system. The procedure consists of inspecting the presence of these

two components on the connector and possibly replacing them.

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 Predelivery checklist.
Please read and review this bulletin first before ordering parts and/or starting the procedure.

Contact your Regional AfterSales Manager (RAM) or the Technical Support Helpdesk if you

have any questions. (Maseratitechsupport@maserati.com)

Thank You for your continued support and cooperation.
