Thanks. The one EVsportline sent looks exactly like that. I'm going to try the - position to see if the instructions are incorrect. They say it should turn off after 20 minutes in the 0 mode and on low voltage in the - mode.
I would check on the app to see if your car is sleeping and go out to the car to take a peak without your phone. That is how I know my radar is off.
Good advice. I just did the hazard vehicle reset procedure and will check it 30 minutes after it sleeps with no phone and no watch.
I don't think so either, unless you leave car idle and unplug for an extended period of time. If you have your car plugged in and idle, then it should not matters at all.
Man, that sucks. That would annoyed my OCD too even though I know it would not doing much to the 12V. Did the EVsportsline magsafe charger changed its design? I have one in my gen1 quad R1s and it is powered by tapped fuse box underneath.
For the Gen2 the EVsporline MagSafe charger comes with an OBD2 adapter. My understanding is the fuse box is not there on the G2. The OBD2 adapter is supposed to shut off after 20 minutes with the switch in the O position (ACC mode) and at 11.6 volts with the switch in the - position (surveillance mode).
I checked my OBD2 port with a test light and only pin 16 has 12v power. Pin 5 is "signal ground" on an ICE OBD2 port and that pin is not populated on the Rivian.
From various reading I have done over the years, I'm pretty sure that the pin 16 constant (never switched) 12 VDC is required by OBDII spec. The other protocol lines, if implemented, must follow that protocol spec as well and it would be unusual for a protocol to sink to full ground. The one possibility is that pin 1 is used by some manufacturers to indicate if the ignition is on or off, but it is "at descretion" of the manufacturer. You may have already seen it, wikipedia has a detailed description of the pinout functions.
I don't know details, so don't ask me, but from what I've heard EVs aren't required to adhere to the full OBD II spec because a lot of it doesn't apply to EVs and they have other diagnostic tools. Tesla doesn't even have a user accessible port at all. You have to plug in to a harness behind a panel.
Yeah, OBD is really two standards - hardware/protocol and diagnostics codes. The same code for an ICE cat converter sensor failure will be returned regardless of manufacturer. I have read that EVs are not required to support the full OBD. Makes sense because 95% of the OBD Standard codes are irrelevant since they are ICE troubleshooting information.
