SummaryTT: 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.
