Sorry, I didn’t.

Did you find a supported brake controller for your Model Y? I have a 22 MYLR w factory towing. Tesla's low voltage system sends 15.5 v to the brake controller wires. Prodigy-Tekonsha told me their operating range doesn’t support 15.5. Tesla disconnected the Aux power to the 7 pin. Which ruled...

Did you find a supported brake controller for your Model Y? I’m still searching for a safe solution. I have a 22 MYLR w factory towing. Tesla's low voltage system sends 15.5 v to the brake controller wires. Prodigy-Tekonsha told me their operating range doesn’t support 15.5. Tesla disconnected...

Have you found ANY brake controllers that support Tesla’s 15.5v low voltage system? I’m stumped after working with Tesla for two years. Towing wiring at the drivers footwell is 15.5 v Prodigy-Tekonsha service lead said they don’t support 15.5v. Tesla disconnected aux power to the 7 pin. So RF...

Hi, this is a great point and could be great news…,did you measure the voltage the connection with the brake controller? I have a 22MYLR with factory towing. Aux power to the 7 pin was disconnected at the factory. Towing wiring at the driver’s footwell is 15.5 . I haven’t been able to find a...

Hi, not sure if it’s related, but it might be worth knowing if you have a lithium ion battery. My 2022 MYLR has a Lithium Ion battery. The power to the brake controller is 15.5 v in the driver footwell.12v aux on the 7 pin was disconnected at the factory. Tesla didn’t communicate to me I...

Has anyone found ANY brake controller that supports Tesla’s 15.5 V. Prodigy-Tekonsha service lead says their operating range doesn’t go to 15.5. They hadn’t tested and don’t know failure mode. Said don’t use it. Tesla disconnected the 12v aux wiring from the 7 pin. So RF brake controller is a...

Check to make sure the trailer has brakes for loads over 1650# (Tesla Owners Manual) over 1500# (CA law - check your state) MY 2022 isn’t currently working with trailer brakes. No power to the 7 pin.

Hi, the brakes and blinkers are working on my March 22 MY. Rocklin service says corp told them it’ll be a two part fix- new set and wiring (harness? module?) I’d encourage taking it in and adding your vehicle to the Aux 12v fix list. The other stuff should be simple. Good luck!

Good points. The MCU and cable was rested on a plastic storage container. I moved everything away to allow for better air flow. It was 100+ in the garage for over ten days.

Thanks. RockyH if it’s showing up in a few threads do you think it was a stealth sw change implemented due to so many heat waves in the 100+ range for days/weeks?

Thanks for sharing. I agree with you. The last software release included games, yippee. I get the privilege of playing video games, polluting the environment and forking out $150 to fill a truck gas tank. (Ok, I’m being snarky, I’ll stop) The trailer brakes are a safety issue too. You’d think...

Yep and 98+ % of the time at 32, sometimes it throttles to 16A. I asked them to run diagnostics on the three PCUs, no problem found. Ideas?

It was charging fine at 32A 98% of the time. It’s cooled 20+ degrees, so will be difficult to reproduce. For now, I’m scheduling charging at 3 or 4am at 24A. I have to decide if there’s any value in installing the wall charger. I want to keep an outlet for the teardrop. They can change the 50A...

Yep, the outlet is capable, up to code, verified by a Tesla preferred installer who didn’t do the original work. I scheduled this after a service visit & the car suggested it was the outlet should be checked. Electrician pointed to the MCU as the likely problem due to 3OA rating. Also...

Interesting. The electrician said to throttle to 24A because of the 30A rating. It has been hot here, long stretches with garage temp over 100. I didn’t even try charging until 4am when CA had the heatwave over 110.

Third year engineering co-op student found a part online. Not rocket science. But does have to be integrated and supported. It wasn’t generally known. I suspect the impact that trailer brake controllers won’t work wasn’t well understood when the decision was made. I also suspect they mistakenly...

12v system doesn’t send power to 7 pin needed for trailer brakes. Tesla service Rocklin is working with corporate on this. The latest update I got was there’ll be a wiring harness retrofit and software. There are a few of us waiting for the fix. I’ve cancelled trips, borrowed trucks, pumped...

Rocky, this is great info. I have a 22 MY LR. I’ve been troubleshooting a charging issue with over temp. I had an electrician come out and was about to install a Tesla wall charger. The electrician said the 50A outlet is fine. But pointed out the Tesla mobile charging unit shows max 30A. The...

I just ran into this with my MY, LR, tow package, March delivery. My brake controller needs the Aux 12v. Trying to get answers from service. The brake controller mfg said all their brake controllers need the Aux 12v.

I have a March 2022 MY, LR, with the factory tow package The Auxillary 12v pin on the 7 pin connector has no signal. My brake lights and turn signals work. But, the brake controller isn’t powered. I have the Prodigy RF controller. The manufacturer says all their brake controllers need the 12v...

I have a March 2022 MY, LR, with the factory tow package The Auxillary 12v pin on the 7 pin connector has no signal. The impact for me is the brake controller isn’t powered. I have the Prodigy RF controller. The manufacturer says all their brake controllers need the 12v auxiliary pin...

I think I’ve just gotten stuck on this 3/4” rise limit. I have a NuCamp Tab 320 S Boondock. I’d asked the SA to clarify the requirements when I purchased the MY LR 19” wheels with towing and FSD. He came back saying the tow height is set by the trailer mfg. I took delivery last week. There...
