Toyota Avalon Service & Repair Manual: Dcm Activation



This function should be used to activate the DCM (Telematics Transceiver) after a new DCM (Telematics Transceiver) has been installed. During the DCM Activation process, the Techstream automatically provides the telematics service provider with the new DCM (Telematics Transceiver) information and deletes the old DCM (Telematics Transceiver) information associated with the vehicle. The DCM (Telematics Transceiver) that was replaced should be returned to the parts department.
