Default CAN Wires - 11-14-2017, 10:05 PM

Random question I'm having with a used install.
2011 335xi E90. Back in the 335 game finally after a few years.

If the CAN wires are not clean and have an issue, would the car even start?
My car will long crank and start but stumble and have a bunch of codes.

Steering wheel controls do not work either, as expected with a CAN issue.

Even connecting the USB to a laptop , I can't get the jb4 to connect.
I'm going to re do the CAN wires in the am but thought it was odd I couldn't even connect to it on a laptop.

Will cause all sorts of issues. If you suspect them just disconnect both wires and check behavior.
