Update. I’m at the DC Space and they’ve determined that my TCAM module in the shark fin is dead as all there resets didn’t work. So unfortunately the module is on a national back order and will take a month to get in. They offered a loaner but I declined. I’m not taking any long trips that will require charger routing.

Mine is getting loaded up (for over an hour now). Not a fan of the amenities. Had to back it on to clear and lift the ramps when the front wheels boarded to prevent bottoming out.

Sigh.

Damn, that sucks. Why did it need to be towed?

TCAM reset loop. Car still drove, but the dealership is 289 miles away. This started with almost exactly 300 miles on the odometer. None of the troubleshooting steps worked. According to CS my vin was one of a string that had duds. Hated that trailer seemed so excavator, not too much luxury sedan.

Bummer. Hope you get it back soon. I have to wait a while for the TCAM module that went tits up in the shark fin. They said about a month. Luckily everything else in the car works fine. It just doesn't know where it is.

do you know much more about which string of VINs were affected?

You can't! At least not when it's not recognizing either of the keys, like our car doesn't. But it will turn off in 20 seconds or so. But seriously, it was so loud and we didn't know how long it would go on for, we ended up running out of the garage and closing the garage door.

You can, all you need to do is put the key in the backup receiver in the center console and then press the unlock button on the door. This will both stop the alarm and fully unlock the car.

Ah! We did not try it in that order. Good to know.

Got the car back yesterday. Initially some of the fanfare had subsided... Then I drove it. Foke yeah. The TCAM is completely functional and truly solidifies the experience. There was a bit of slop adhesive by the shark fin, but it came off with ease.
Was able to pair our Pixel 6 Pro(s). I waited forever to discover the car... It never did. That is until I went in and ran through the PAK setup via the tablet. Then the notifications and pairing started to roll. It was this way for both our profiles.

I will shoot my contact an email if you still want to know.

Nice. Glad you got your car back and that everything is as it should be. Still waiting for my part to come in. But other than that my P@ is running great.

Just got a call from the DC Space. My TCAM module is in early

While the OP of this thread thoroughly documented what is most likely the the correct way of doing things, as I posted in the past I never bothered to do that, and this time I took photos to demonstrate the quick way of doing this: 12V/TCAM BATTERY DISCONNECT PROCESS - RON SWANSON METHOD

Thanks for this quicker TCAM disconnect method, @kkonstan! I've added a footnote linking to your method in the original post.

Introducing the TCAM recovery kit 😂

 

[Cephas]

Just did this after I received an SOS / eCall warning and then the GPS went down. When I called customer service, they said I have to go immediately to a service center as it was NOT the TCAM and it was an emergency signalling failure (or something like that). I did make an appointment at the service center after that but told the rep I would try a few things first.

Now its fixed thanks to mtg35 and kkonstan and the rest all for this fix! Saves me a looooooong day (at least) at the dealer, 90 miles away.

A couple hints:

1. Remove the storage cover from the hatch so it doesn't get in the way (obvious, but I didn't at first)
2. To release the TCAM battery from its inexplicably tough-to-get-to hiding place, I used a short, small flat blade screwdriver gently inserted right above the wire harness connector (from the rear of the battery). Working on Volvos all these years I have had many thrilling instances of dealing with parts that are almost purposely placed in hard to access places.
3. And to release the wire harness connector from the battery, as per the main post, use a tiny flat blade (I of course couldn't find my set of tinies and used a metal pick) to pull the tiny tab towards the wires.
4. Don't drop the battery while disconnecting!

Thanks again.

P.S.: I asked the service center if they had TCAM batteries or TCAMs themselves in stock in case we need to replace one or both, and they said no, they do not stock them, so try this before dropping a vehicle off for who knows how long...

Hi folks, i just got the SOS notification couple of days ago. My keys wouldn't unlock the car but luckily the phone app did so i was able to get in. Car would drive if key was in the cup holder but besides the SOS icon being on, i had no gps and doors wouldn't lock/unlock.

Called customer support. They told me to try the reboot using the defrost button trick. Did not work. They then said drive the car until it gets to 15% or below battery and then charge it up to 90%. Did that and did not work.

So it being now a Sunday and I had nothing better to do, i tried the battery trick instructions here. Took about 20 min as it was my first time. It worked! Thank you for the step by step instructions. Not hard at all.

Car is completely back to normal. This was my first TCAM issue. It's a 22 model year with a build date of Dec 2021 if that helps anyone.
The customer support person said they've been getting lots of calls due to the 2.1 software update so hopefully when 2.2. arrives, it'll fix this problem.

I'm having the same problem you described, except navigation is working for me. The service center rep told me that 2.2 will fix the problem.

Navigation usually works for some time after the key fobs don't work problem manifest, at least in my case.

It usually stops working a few hours or a day later.

Is there a video on this?

thanks

Give it a few months mine is bound to fail again, I’ll record one

I got home from work today and experienced this issue - with the key becoming totally unresponsive. I've joined just to say 'thank you' for posting these details!
