[Ovmsdev] CAN bus noise?

[Thomas Bergo]

I haven't experienced any issues with traction control, but when i
disconnect the OVMS module i can hear one "click" sound form the front of
the car.
Have also read that the same is happening on the Nissan Leaf when
disconnect the CAN-Bluetooth adapter used with Leaf-Spy.

No issues, just this click when disconnecting. Does anybody else
experienced this click when disconnecting the OVMS module?


Regards, Thomas
