Maybe somebody knows what code need to sent to EV/CAN bus to start heater or cooler like it does with Nissan Connect?
I want to start A/C when car is switched off.
So while the Carloop is asking for the Climate Control to start, the TCU is sending a message (every 100 ms) to the Climate Control to not change, and the Leaf's VCM would not be expecting to receive such conflicting messages. After much testing I found that it usually works to send the 0x56E messages more often than the TCU, and send them for longer than the TCU would when it starts the Climate control. I settled on sending the bus wake-up (0x68C 00) , followed 50 ms later by 0x56E 4E 08 12 00 to turn on Climate Control, then delaying another 20 ms and repeating this Climate Control command another 45 times at 60 ms intervals.
