| T-TT-0442-17_Rev | 2019-05-13. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; EQUIPMENT:ELECTRICAL. TT: Safety Connect is a vehicle option which requires a subscription fee for the system to be active after the initial trial period. Once the subscription has expired the DCM (Telematics Transceiver) will be in an inactive state. In some instances, a DCM may need to be replaced even though the customer is not using the service. If registration of the replacement DCM part is attempted using the Techstream utility after the account has become inactive, the registration will fail, and messages such as ?ATX webserver is Down? or ?ATX error? will be displayed. |

| T-SB-0047-19 | 2019-05-13. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:SOFTWARE. TSB: Some 2018 ? 2019 model year Toyota vehicles equipped with the Entune? 3.0 Premium Audio Navigation System require a Special Service Tool (SST) USB flash drive to update the map, points of interest, and system software. The SST is used with applicable vehicles to deliver the update; however, the process for generating license keys differs from previous generations. Before attempting to perform a map update, the head unit?s expiration date must be checked. If the expiration date is still valid, a license key may be generated without the use of an activation card number. Updating the maps without the use of an activation card number is considered an Embedded Navigation Update (refer to pg. 9), and performing this process does not extend the duration of telematic map services. If the head unit?s expiration date is expired, or is expiring within the next 90 days, it should be recommended to the customer to purchase an activation number. Utilizing an activation number will initiate a Dynamic Navigation Update (refer to pg. 2). This Dynamic Navigation Update will perform the Embedded Navigation Update and provide telematic map services for a period of two years from the day that the Dynamic Navigation Update is performed. Activation card numbers are provided in an activation card number pamphlet available through the normal parts ordering system. Follow the process in this bulletin to perform the update. NOTE Map data is released once each year through the shipment of an SST USB flash drive to each dealer. The SST MUST be stored in the SST cabinet to ensure it can be easily found |

| T-SB-0020-19 | 2019-03-25. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:FAN/MOTOR; VISIBILITY:WINDSHIELD. TSB: Some 2018 model year Camry and Camry Hybrid and 2019 model year Avalon and Avalon Hybrid vehicles may exhibit decreased front windshield defroster performance at extremely low ambient temperatures. This condition may be the result of the fresh/recirculation servo actuator separating from the servo. This condition does not affect the airflow of the defroster. Follow the Repair Procedure in this bulletin to address this condition. |
