Dealer replaced the TCU module (DM5Z-19K350) today but MyFordMobile still cannot communicate. Don't Ford technicians have a way to test the connection rather than have the customer try a variety of resets and reloads of MyFordMobile apps? Seems to me that the technician should be able to troubleshoot the problem without the customer (me) trying to rule out software problems on my phone or computer.
That's a nice thought, isn't it?
Not from my experience. Seems like the general dealer responses are to plug the car in and see if there are any error codes. If not then whatever you think is a problem isn't really.
And if it involves anything online then the answer is frequently to just accept it not functioning or try asking someone at the website for help with your car.
