Safety Connect System – Vehicle Location Inaccurate
Specific information for Region support is provided below.
Condition
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: Toyota 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. Toyota 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 K0P. 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 (19TE12).
Dealer Notification
The attached dealer letter will be sent to all Toyota dealers on October 17, 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.
