New to diesel world plz help

Hello everyone. I am new to the diesel world and need some help. I bought my first diesel vehicle recently, an 08 F350 xlt drwd. The following codes came up when I hooked up the scanner to it.
P0684-Glow plug control module

P0420-o2 sensor or cat

P2002-dpf bank 1

P2452- ?????

What would cause these codes to go come up and what can I do to correct them? Also from time to time, my truck will let out white heavy smoke from the exhaust. It comes and goes. I've heard that diesel trucks smoke sometimes but I don't think what my truck is doing is normal.

And last but not least, wiring fault on trailer message. How can I correct that problem. Thanx in advance. Any help will be greatly appreciated.

Tbcm fault is usually from dead batteries or a bad tbcm that doesnt light up. That smoke is regen and is normal on a 6.4.
The glow plug module code is a bad gpcm or a halfazz plugged in connector, you gotta push hard to plug them in.
The other dtcs are prolly from a bad dpf pressure sensor, hose to sensor is broke, or harness side connector pigtail, more likely the pigtail connector pin fitment. Which may be contributing to irregular regens.
