Default 09 H3 - FAILED SERVICE - STAB SYS - TRACTION Warning lights

09 Hummer H3 - 124k miles. Getting the POWER REDUCTION - FAILED SERVICE - STAB SYS - TRACTION CONTROL warning lights. Put in brand new battery, new accelerator pedal assembly, checked all fuses and 12 spot and Transfer Case Control module keeps burning out. Got the following error codes from diagnostics. Any suggestions on what to address next esp work I can do before going to shop? Many thanks!

Is your transfer case fuse (#12) blown?

When you put in the brand new battery: 1) was it fully charged .... off the shelf from auto parts does not mean it was fully charged as they can sit there for months, and 2) are you still using the OEM crappy Battery Terminal Connectors?
