Cybertruck bricked

[CyberSDoc]

Might be temporary?

Unfortunately the same issue this morning. Briefly goes green, low pitch whining sound, and the "clunk" followed by the error.

80 mile drive back to another service center on a Sunday.

Before you go... Call Tesla. I had a problem when I first got my CT. I was able to call and they did charger and truck diagnosis remotely. It might save you a trip.

Unable to call on weekend. Wife was heading up near a service center so dropped it off at the SC parking lot. We live atleast 1 hour from a service center so it's hard to coordinate rides. Dropping off on a weekday and picking up a loaner is almost impossible with work/kids. This marks our fourth visit since within the first 8K miles or 9 months. Phew....

Luckily we have an 7 year old model x that has the same amount of service visits as the CT and (hate to say it) an ICE vehicle for when the teslas brick.

Wonder if OP got hers/his CT fixed the second time around.

My guess 48v battery is dead or weak.

Same issue with mine. Refer to my post. Nothing you can do. I'm at day 5 in Tesla service!

John (op) how is the truck working?

Follow-up on my bricked CTFS. It was diagnosed as a PCS Power Converter. Tesla was able to correct in about 8 days.

It's pretty easy to put together a viable 48v power source, either as a conversion from 120VAC or battery-powered. But it's kind of interesting that there isn't a product ready for that yet. Seems like Chinese are missing out on this opportunity

Lab or telecom power supplies work.
Tesla used an EcoFlow battery to 120V AC to power supply (module, not lab) to run Cybertruck in development.

No shortage of DIY options. I am just saying there are plenty of jump starters for 12V applications, but nothing yet for 48V.

There are 36V and 48V battery chargers for boats and golf carts. Just need to find the older style without all the smarts that prevent charging into an open circuit.

Lab power supplies aren't all that expensive, either.

But isn't the truck designed to reboot given 12v anyhow?

Yes, you can powerup on 12v enough to open the doors. But it lacks the power to operate everything that the 48V battery can.

12V operation is limited due to the control module needing to boost it to the 48V bus voltage.

Here is an example unit that can be wired to a 12V jump starter to produce 48V:

The only question is what current is needed to more or less get the vehicle back into operation.
