05 HV batt & cooling fan questions

I tried searching the archives but couldn't find the info I was looking for.

I picked up this 05 with 110k back in February. Averaged 40 mpg's. I changed inverter coolant pump and fluid as well as ICE water pump when I first got it along with all fluids and filters including cabin air. Everything was going great until I started using the AC.
I noticed the HV battery would drain rapidly and the ICE engine would run much more often. About a week passed and I got the triangle of despair.

First thing I noticed was when I command the HV cooling fan to turn on with my scanner, it's turns on low for about 2 seconds. No matter what speed I command 1-6, it is low speed for about 2 seconds. If I pull the fan (yes it's clean) and put 12v, she blows like she's short on rent. Surely this isn't normal, or is it?

I purchased the Bentley and honestly, pretty disappointed with the lack of info.

Does anyone have a troubleshooting thread on this?

I intend to replace the battery pack but I want to make sure I don't end up with the same results.

Most modules range from 7.62 to 7.54. except for 2 that are much lower. 7.34 and 6.32

 

Yeah definitely a low capacity module. I'm just hoping the cooling system is operating correctly.

 

I have the zurich zr8 and Innova scan tool. They are really similar. I have a tech 2 clone and a blue tooth scanner. The zurich zr8 is a really well rounded scanner and that's the one I'm using to command the test.

I tried holding the gas and brake to charge things back up but after resetting the code but it comes back immediately. Still doing my research on the next step. Rebuilt vs new vs upgrade to project lithium...
