I don't know what module the TMM is but U1016 means it lost the network. If the code is CURRENT then the TMM is offline.

The DDM is the Driver's Door Module, and U1713 means "Loss of Front Door Module to Window Motor High Speed Comm." or, it's lost the network.

The RIM is the Rear Integration Module and B1328 means "LH Sun Load Sensor Fault" which is a minor problem with the A/C.

I think it's clear that you have problems with the wiring harness under the hood, particularly the network line, which is usually the PPL wire.
