telematics control unit

Has anyone tried to pull anything from the tcm connector? I’m curious how the traffic from that little box looks when the head unit calls out for it to do something. It could allow for a cleaner integration with the car than just attaching to he OBD port.

I had an incident where the battery level on my leaf when into a nosedive while driving. I took measurements from leaf spy and brought them with me to the dealer. They found a few cells that were aging faster than the others but were still within spec. I'm at 75k miles and have 11 bars. The...

I'm having trouble with your code. When set up, if I change the name from "car" to "Rhapsody," the home app in iOS will add it as the new name, but Siri will only respond to the room it is set for. If I ask about the charge level, it will respond "battery's battery is at 0%." Finally, I...

Has anyone successfully tied OVMS into HomeKit?

I haven't found that anywhere. Why would nissan put it there?

I ended up ordering these. The left side seems a bit off but the right it's fine. No problem spotting deer now, though. https://www.amazon.com/gp/product/B01KHUYM88/

The stock halogen high beams on my SL annoy me. I’m looking to upgrade them to a color matching LED but I’m not sure which ones are a bad idea. I want to make sure it’s polite to other drivers, though you don’t actually use high beams unless there’s nobody around to blind anyway so that’s kind...

I remember seeing a db9 port on the inside of my GE durastation. I’m wondering if I could pull charging status or anything interesting for that connector. Has anyone taken a look at what it is?

No I understand hex. I don’t understand the shortcuts we were taught for it in computer science, but I was able to figure it out as a kid when I had to make some of my own gameshark codes. (Who actually collected all the stardust in legend of dragon? Nobody!) Another part of my project...

If you want to develop for this car, I recommend the particle electron board. Works great here and has built in cellular connectivity and CAN bus support. The web IDE is really annoying, though.

There were plenty of things already done. I got stuck trying to understand twos compliment (I think that’s what it was called). I couldn’t figure it out and rage quit.

I really wanted to make my own solution to this, and made some progress, but I got bored, then busy, so it didn’t get anywhere.

The website works, the app does not. I’m in the US.

Thank you!

For weeks, I haven’t been able to get my phone to talk to my car, but the car can talk to Nissan just fine. If I tell carwings to do something from inside the car, it’s fine. Each time I’ve called Nissan, I’ve been told they are undergoing upgrades and the system should be online again the...

I'm trying to get it via the can bus.

I cannot seem to get a number that makes sense for charge time remaining. Are there any examples of how others found the time remaining until full charge? I can't find one.

Can I see a diagram or photo of what I'm supposed to disconnect?

Is there a way to open the charge door via CAN bus commands?
