Safety Connect System – Vehicle Location Inaccurate
Specific information for Area support is provided below.
Condition
The Data Communication Module (DCM) in the subject vehicles are 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.
Dealer Notification
The attached dealer letter will be sent to all Lexus dealers on September 12, 2019
DCM-12 or DCM-13/14 Re-Recalibration
During DCM-12 or DCM-13/14 recalibration, it is possible for the recalibration to fail. In the case of recalibration failure, the technician can
re-recalibrate the DCM to the updated software type by performing some additional steps. Re-recalibration will require removing the DCM
from the vehicle and the utilization of a specially provided cable to directly connect to the DCM. If a technician experiences a calibration
failure, the Technical Instructions inform the technician to contact their Field Technical Specialist (FTS) for assistance. The FTS will be able to
provide the following opcode for dealerships that experience this condition. This opcode should only be provided in cases where dealerships
need to perform a re-recalibration on the DCM.
KLG005

Please reference the attached Dealer Letter for additional details.
Please review this notification with your staff to assure that all relevant personnel have been briefed regarding this subject.
Thank you for your cooperation.
