Would be good if someone could confirm my observations are reproducibleso i guess connect the plug before doing a software update?

I plugged the connector back in mid downloading of the update and the update vanished lolWould be good if someone could confirm my observations are reproducible
I did not have any issue with upgrade to 2024.3.15 without connecting the canbus. They were left disconnected all the time.Would be good if someone could confirm my observations are reproducible
Excellent. Good to have that datapoint.I did not have any issue with upgrade to 2024.3.15 without connecting the canbus. They were left disconnected all the time.
Updated to 2024.3.15 today as well. Can confirm it did not fix this issue. Error codes PCS_a022 and UI_a112 keep popping up when the car is parked. Car did not sleep. I have aftermarket dashcam installed and can hear from the parking mode footages the clunks of the contactor.So when that happened, the version was 2024.3.15. A bit later the car got another update, which said 2024.3.15, and after installation it said 2024.3.14 in the display, but TeslaMate/app are showing 2024.3.15
Car still doesn't sleep. Going to disconnect it again.
I have not seen any other system(s) affected in the 5 weeks or so since I disconnected the 2 wire connectordo you know if this cable/connector controls any other function of the car?
Kinda like a smart phone, right? I sure am glad I do not have to take my phone to the AT&T store every time a security update comes out!Updated to 2024.3.15 today as well.

Can't remember where I saw it but someone said Tesla staff told them to wait for this to be resolved after the 2024.12 branch.
I used to think it was super cool that a car can get software update over wifi and gets better with time. Not anymore as inexplicable bugs like this pile up.
Good to know - glad Tesla is doing better than the rest! I just think the reliability and the traditional longer life cycle of a car, as opposed to a smart phone, inevitably get sacrificed, as software advances faster than hardware can keep up, creating lags and bad user experience, while the risk of software errors and the complexity of fixing those errors also increase.Kinda like a smart phone, right?

While it does feel like these issues are unique to Tesla, I can assure you that it happens to other brands as well. Don't get me started on VW or Chevy, let alone Fisker or Lucid. I have a family member with a 2021 Range Rover Velar, and he had issues like we are facing multiple times. Including having to put his car in "limp mode" just to be able to slowly drive to the dealership.
Thank you for confirming that and easing my concern a bit. Disconnected it as well. So grateful for this thread, ending the alerts/nonsleep/phantom drain issue for now. Hopefully Tesla communicates something officially soonI have not seen any other system(s) affected in the 5 weeks or so since I disconnected the 2 wire connector
Absolute insanity. Imagine this happened out of warranty and then they revealed after thousands and thousands in repairs that it was the retrofit.Man I am so glad I found this thread. I've been having the exact same issues with my 2020 LR with the power trunk retrofit kit installed. Tesla has replaced the front left sensor (twice) and even the car's main computer once in an attempt to resolve the HVAC system not working reliably. Fortunately it was all under warranty -- especially since it didn't fully resolve the intermittent HVAC failures _or_ the phantom drain.
At my last service appointment (last week), they finally acknowledged that all of my issues are actually because of the trunk retrofit. They offered to disconnect the wiring harness for me but I opted to leave it connected since I knew that there was an imminent software update. Unfortunately, the update didn't resolve the issue but since @FastGTR was kind enough to post that pictorial walkthrough, I'll just go ahead and disconnect the harness myself now.
And I'll learn from @ParaAdBellum and make sure I've reconnected the harness before applying the next update.
I did not have any issues upgrading with the cable disconnected. Everything behaves the same after the update.I did not have any issue with upgrade to 2024.3.15 without connecting the canbus. They were left disconnected all the time.
I can't disagree with that sentiment at all. As excited as I was to get the "official" power trunk retrofit installed last fall, I've now come to really regret spending the money on it.After reading this thread, I'm not even going to try reconnecting it, because it seems update didn't fixed it.
Starting to think that Tesla should recall the retrofit and get a better version out.
My exact words when HAL does something freaky.fixed itself. random. gotta love a computer on wheels.
That's me - 2019 Model 3 out of warranty end of Sept 2023, and I had Tesla install the powered trunk retrofit in Oct 2023. I paid $1000 for Tesla to diagnose and replace VCFRONT to try to correct the HVAC issue but am I glad I found this thread! I was going to get Tesla to replace my blower motor but now I'll just sit tight and wait for the software fix. Tesla Toronto never told me my intermittent HVAC issue relates to my powered trunk retrofit.Absolute insanity. Imagine this happened out of warranty and then they revealed after thousands and thousands in repairs that it was the retrofit.
