Electrical gremlins 2017 Cascadia!!!

Thats a bunch of codes, a little of everything. I would at least start with inspection of battery cables, fuses and grounds. Then a good look at/around the ECM. Have you done anything recently to the truck?

 

You may have a CAN (Controller Area Network) Bus malfunction.
Either the 5 Volts sensors power supply is lacking.
Or the ECU may lack a proper communication with the other modules (VCM, TCM, etc...).
The other posters advised to start checking on battery connections, fuses, grounding, etc...
Once you finish those checks, you should check the actual Bus.
There are YouTube videos on proper checks.
Basically on the 9 pin connector:
PIN A is GROUND, PIN B is BATTERY POWER,
PIN C is CAN 1 H, PIN D is CAN 1 L, PIN E is SHIELD,
Bus Hi or Low no short to the ground or between them.
No Bus interruption (open circuit).
Without power applied (battery disconnected),
the resistance between Hi and Low should be 60 Ohms.
If it's different, then, one or both 120 Ohms
resistors closing the Bus are bad or missing.
Once the proper physical integrity is established,
The ECM connector and all modules connecters
should be checked for pins integrity, cleanliness and lack of corrosion.
Usually after battery disconnect, most of the inactive codes are cleared.
If everything checks OK, but codes are still present,
then, you need a Service Tech with a Service Tool.
Good luck. Keep us posted, after repairs are done.

 

A greasy technician hand removed that connector.
After the connector was re-applied, a dirty or damaged pin or pins prevent a proper electrical contact.
To be re-checked by the owner ASAP.

 

Sure bet.

 

Could the kill switch be messing up the ECM memory?

Codes reflect what didn't work, clearing up on their own may be the ECM 're-learning' all those parameters?
