Component: Equipment: electrical: navigational system(global positioning system)
Summary: Area Letter: The Data Communication Module (DCM) in the subject vehicles is equipped with software to identify the location of the vehicle using the Global Positioning System (GPS) to support features of the Safety Connect system. Due to incorrect programming in the DCM software, after November 2nd, 2019, the GPS coordinates for this system will be calculated incorrectly. This will cause the system to use incorrect vehicle coordinates if one of the system?s features is activated. Note: Lexus has initiated a Limited Service Campaign and a Customer Support Program to resolve this issue related to the Safety Connect system. Both of these programs provide the same free remedy to correct this issue with Safety Connect. Lexus recommends that customers have the free remedy performed before reactivating Safety Connect. Vehicles that had an active Safety Connect subscription on or after 10/1/2017 were included in Limited Service Campaign LSC KLG. Vehicles that did not have an active Safety Connect subscription on or after 10/1/2017 but are affected by this condition are included in this Customer Support Program (19LE05).
