becoming inoperative when attempting to send commands to the vehicle. To simplify the diagnosis of


Make sure the vehicle is in an area with DCM 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
o Test the customer’s Remote Connect app for functionality
 If the app is now functioning normally, no more action is needed. Please note, this

phone and compatibility issues with the app.
 If the app is still not functioning, verify the DCM operation and continue diagnosis
via the applicable repair manual.
