I recently had a v5 module sort of do the same thing for no reason; just stopped responding (can lights go solid as soon as i plugged it in). idfk...

the module talks via the iBus, so maybe it was spitting garbage out and the car didn't like it and somehow triggered the fan; i know that when doing an ECU flash, the fan will go full blast, and eventually requires the ecu fuse to be pulled to reset the system to finish the flash. sounds similar...

the new v5 pcb does have an ESD diode on both lines, but that's just for ESD protection. The inductors aren't necessary, and the pulldowns via caps are prob for ac coupling or something. i haven't had any chips go bad (that i know of) so I don't think it needs anything else but who knows.

there isn't a loopback test, but that would be great to implement (cough, cough, *karlis*, cough ;)
