Toyota Remote Connect App May Not Operate
Some owners of 2020 Toyota Highlander, Tacoma, 4Runner, Camry, RAV4 HV, Camry HV, Highlander HV, Tundra, RAV4, Corolla hatchback and Sequoia vehicles may experience the inability to activate Remote Connect or Remote Connect becoming inoperative when attempting to send commands to the vehicle.
To simplify the diagnosis of this system and prevent the unnecessary replacement of parts, please refer to the following procedure.
Make sure that the vehicle is in an area with DCM (Data Communication Module) signal. If the signal is non-existent, move the vehicle to a better area.
Disconnect the battery for 15 minutes to reset/initialize the DCM. Test the customer’s Remote Connect app for functionality. If the app is now functioning properly, no more action is needed. Please note that this condition may occur multiple times as this could be caused by the customer’s phone and compatibility issues with the app. If the app is still not functioning, verify the DCM operation and continue to diagnose via the applicable repair manual
