My MS doesn't have one (and I doubt they would remove a plug for export), I thought I'd also read that some Tesla's that did have them only had the 12V and GND pins connected, no CAN bus at all.Every car sold in the US since 1996 is required to have an OBD2 port.
Yeah I don’t think they actually do anything useful in a Tesla, you’re right.My MS doesn't have one (and I doubt they would remove a plug for export), I thought I'd also read that some Tesla's that did have them only had the 12V and GND pins connected, no CAN bus at all.
On my MS I'd need to buy a break out adapter to access the CAN bus(s) and remove a panel to access that connector.
I 'think' the rules are different for EV's because nobody needs to check for emissions compliance tests with a scantool.
You could use the fuse panel to hardwire your dashcam in, its a little bit of work but not difficult at all with the correct hardwire kit for your dashcam.So it's confirmed that 2021 refreshed MS doesn't have the port, even with 12v and GND only? I just need it to power the dashcam.
Actually, I don't think there is any need to get an exemption. The OBD-II regulations which require the OBD part are actually a subset of the emissions certification approval. Given there is no gaseous emissions certification required for the full BEV, there then also is no OBD-II requirements. This is why you do not see a MIL or 'Check Engine' light as that's also a requirement under the OBD-II regulations.And now I’m reading the 3/Y don’t have them at all, presumably because they were able to receive some sort of exemption, so it’s reasonable to think the refresh S doesn’t have one either.
Makes sense although there's clearly been some sort of evolution of thinking/guidance on the topic over time, as they felt compelled to include the port in the past, even in a completely useless form.Actually, I don't think there is any need to get an exemption.

This also is part of the reason that Tesla has been able to get away without making service literature available to general public at a 'reasonable price'. That's actually required in the US under what is known as SIR, Service Information Rule, which was also implemented as a requirement under the Emissions certification requirements.
If you are looking for a fuse panel on a refresh Model S or X you will be disappointed. No fuses or fuse panel, E fuses only.You could use the fuse panel to hardwire your dashcam in, its a little bit of work but not difficult at all with the correct hardwire kit for your dashcam.
@Dakster - you may want to check what the input voltage range is for the Blackvue. With Tesla having gone to a lithium ion battery on the MS the low voltage system appears to run upwards of 16 volts depending upon the state of charge of the low voltage battery. There is a recent thread where an owner was trying to hook up a radar detector as was running into it throwing high voltage faults and causing problems.I just checked my refreshed MS LR and I do have a OBD port! I checked pin 4 (GND) and 16 (+V) and got 15.39v DC, so this is a good sign. I'll be hardwiring my blackvue here using the OBD --> Cig. lighter adapter from Amazon.
Good news. Where is the port please.My 2021 Model S Plaid DOES have an OBD port.
it's on the driver's side foot well. Power coming out of it was around 15.4v with car off.Good news. Where is the port please.
Thanks!it's on the driver's side foot well. Power coming out of it was around 15.4v with car off.
You can also use the stock cig lighter plug in the center console (forward compartment, somewhat hidden) and run the wire up to your cam.I just checked my refreshed MS LR and I do have a OBD port!

Dont think so, as to your point the main battery charges the low voltage battery.My BlackVue dashcam came with a Magic Pro which lets you cut off the power to the dashcam once the power drops below certain volts.

I am wondering if I need this use this in Tesla since the low volt battery would automatically get charged from the main battery once it gets low (I am assuming). What do you think?
