Guessing, but could it be a power relay? Something detecting 12V accessory?

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?

Except that with FEATURE_CANWRITE set to zero (as it is), the bus should be in listen-only mode.

I have read somewhere that if you connect a bluetooth adapter with "torque" app you can disable the power steering (or was it the ABS)... so I would speculate that what you are experiencing is not a problem of noise, but rather a problem of the software that was uploaded in the ovms. Only speculation though.

Subject: [Ovmsdev] CAN bus noise?

I am concerned that the OVMS v2 may be adding noise to the CAN bus, or causing problems in some other way (I know very little of CAN hardware, so can't really speculate much).

I have heard other people mention CAN errors when OVMS is connected and yesterday I made my first trip with the unit connected to my C-Zero. During this trip the traction control failed - something it has never done before. The problem went away when the car was turned off and on again, but it seems too much of a coincidence for this to be unrelated.

Does anyone have any opinions on this?
