Please See Tech Tip: T-TT-0442-17 Condition: Safety Connect is a vehicle option which requires a subscription fee for the system to be active. The trail period of service is provided upon the vehicle purchase. 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. Recommendation: Confirm Safety Connect status by running a vehicle inquiry on TIS (this can be done by your Toyota Dealer) which will provide Safety Connect account status. The vehicle repair manual instructs the technician to perform a DCM activation after replacing the DCM. However, if the subscription has expired, the DCM cannot be activated because it does not have active cellular service. If a DCM is replaced and the Safety Connect subscription has expired, do NOT perform DCM activation. In this situation, the DCM should be installed without performing the DCM activation.
