After looking through the possible causes of some of those codes, the most common things seem to be CANbus/TIPM related or the PCM.


If you're certain there's no issues with the engine bay grounds having corrosion under the crimp and insulation where it can't be seen. you can try checking the wiring harnesses for any damage due to rubbing on the chassis, etc, and check the PCM and TIPM connectors and make sure they're corrosion free, properly seated and tight.

 

It's not uncommon for lots of seemingly unrelated codes to set after a full reset or battery change. As various modules boot up and power on, they can come up out of order causing other modules to set codes due to lack of response. I would clear all codes now, cycle the key off, then back on and see what codes return.

 

Yes, that has been tried more than once. All codes return as active.

 

Drivers side below the battery is a hidden relay block that if it goes bad you can re-pin the block for under $10 of parts from Amazon and about 2hrs of Patience. It will give you most of those codes if it gets corroded. There are videos on YouTube that show how to fix and re-pin relay boxes. You can access the relay box through the front driver's side behind the tire. Do this first before replacing the tipm.

 

do you have a list of parts used by chance?

 

So I replaced the PCM but no change unfortunately.
Will keep troubleshooting. Im leaning towards the relay box on the driverside near the wheel-well, or my TIPM.

 

Tipm....get a used on at savage yard
