It is possible wake up Leaf through CAN bus?

Tue May 16, 2017 2:37 am

Hi,

I have a question. I have First Generation Leaf with Wifi OBDII. The Leaf is connected to the grid. I want to wake up CAN bus through the serial port to communicate. It is possible? Send some AT command to wake up?

Thanks

Some Gen 1 cars require a wire to be toggled to 12v to wake up the system before you can send commands. I unplugged the TCU on my Gen 1 Leaf and connected the OVMS to it's plug to access the EV system activation request signal. See https://carrott.org/blog/archives/158-O ... ntrol.html

See viewtopic.php?f=44&t=23038 for detail of the can bus method that works on later cars.
