I can confirm that the "christmas tree lights" can be triggered by a 12V battery undervoltage, which usually results from draining the battery....
That makes a lot of sense. I too was wondering how you could pull enough current over that pin to drain the battery but not break anything! I'd...
The pins I've circled in red here are the "Control Pilot" pins, and my working theory is that they're how the 12V battery charge is leaking out of...
Do you happen to have a multimeter with a diode test mode? If so, could you try testing the control pilot line on the third-party adapter to see...
FWIW, after assuming it was the evaporator and taking the whole dashboard apart to verify, it turned out not to be a dirty core like I thought. In...
The evap core is really annoying to get at and unfortunately not really a reasonably DIY-able fix. You gotta disassemble the whole dashboard to...
Haven't had that problem myself. There is an spot on the interstate near here that kills my wireless dongle's CarPlay connection every time I...
Update: turns out you don't technically need to pull the wheel. You can pry out the top trim part from the urethane overmold to the screws holding...
Update: replaced the switch. Turns out I read the diagram wrong and you don't actually need to pull the steering wheel. You do need to pry up some...
Looks like Teslas use a proprietary extension to the J1772 signaling standard; they can switch to a mode where the Control Pilot line is used as a...
So I've found at least one other vehicle-side charge controller, the New Eagle VPIM v7, which has a separate "control pilot feedback" line, and...
Don't think I'm right about the proximity pilot, actually. Checking the wiring diagram, the control pilot line has a transistor connected which...
I had an Amazon-special L2 EVSE die on me recently, and when it died my 12V battery drained as well. I'm guessing that the current in the...
If you get the 4/5 bars, the TCU is on the CAN bus, booting, and getting a connection. Your problem is likely on the HondaLink side. (Personally,...
Sunnypilot user here, 5k miles in. Everything works fine. The proxy box installed in the dashboard has no side-effects and is invisible to i-HDS....
My guess is that running the car in reverse heated up the battery, changing the cell voltage slightly.
Same issue here. Dead switch. Replacement requires pulling the steering wheel to get at a pair of screws on the back side, but is straightforward...
Same issue here. I didn't realize it was the switch, because I figured the (+) paddle increased regen, and pulling it would always show one...
Ottocast makes a wireless CarPlay dongle that works a treat for me.
The Telematics Control Unit is on the left side of the trunk behind the tire pump kit, and the car works fine with it disconnected. (In fact, it...
