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.

We are forensic investigators and require the DCM in our new 2019 Corolla to be totally disabled or preferably removed in order to protect our location data from being available or broadcast. It is currently disabled and all spying services off line but the ignition ping to the cellular system is still a concern. Please respond.

How did you disable the DCM and turn all spying services off? I read that in some older models the DCM is optional and can be installed at the dealer (I read this in a U.K. Toyota forum). If this is the case, you should be able to unplug the DCM if you can locate it. Toyota corporate/dealerships are zero help for turning off the data collection.

Could you please provide how to disable DCM ?

It is actually embarrassingly easy. Simply go to the fuse block in the engine compartment, and pull the MAYDAY/DCM 7.5 amp fuse. This turns the DCM into a brick and also disables the right front speaker of the entertainment system, since Toyota Spying Apps uses that speaker to 'communicate' with the driver. So, the next time you start the car, you can confirm that the DCM has in fact been bricked if the right front speaker is disabled. There is a method to reactivate the speaker without the DCM involving exposing the DCM in the dash and jumping two sets of contacts, but that is really not necessary. We simply adjusted the right rear speaker to compensate for the dead right front speaker and do not notice the difference.

This is the link with details of how to disconnect the DCM and also re-activate the right speaker if you so desire:
