THC_d0005_pumpBat1 and THC_w0052_sanityPumpBat1

[brainhouston]

Anyone seen these codes and what they could mean?
Not really finding anything on the web, except below but i don't have other codes so it makes no sense...

THC_d0005_pumpBat1
The coolant pump DTC is set on the Thermal Controller (THC) if the following warnings occur repeatedly over a specific time frame.
THC_w0039_pumpPTLimp is set for 300 seconds or 100 times with less than 30 minutes between each occurrence.
THC_w0040_pumpPTStop is set for 120 seconds or 10 times with less than 30 minutes between each occurrence.

If you open a service ticket from your phone, I believe all of the errors will automatically be entered into the ticket. I'd let the Service Center explain them all.

I'm assuming you have a 2016 mx a service article states to check the ground under the front trunk near air compressor or maybe its just disconnected

So issue was blown fuse, F137

Full story.
Had above codes and my pump bat2 (wasn't sure at the time) was running all the time even if car is locked and loud too.
On diagnostic screen it showed ??/-- for Pump Bat1 and Pump Bat2 at 100 %
Swapped the pump just in case no change.
Dug thru schematics n ck the fuse n it was burnt. Replaced n Pump 2 immediately quieted down, both pumps showed ~25%
Did Power Off n everything stopped (previously didn't).
Now just need to figure out why Chiller Bypass is ??/--

Actually after looking at Service/EPC docs for X/S and "Tesla Thermal Management System - explanation" thread, maybe Chiller Bypass dashes is normal on X.
Picture diagram seems to be from S, with 2 condensers so Chiller bypass might have just carried over...
But i'd love if someone else confirms.

S:

X:
No mention on Chiller bypass anywhere...
