Secret Micro USB Port Inside Overhead Trim [TCU Connector]

[mongo]

Mongo, do whatever you want playing around with this port.

There are 3 CT's here in the service center due to a few people playing around with it. $3.5k each one so far. The internal Steer-by-wire unit is dead on each occasion.

Opens are rarely a risk on a loop. However short it out with a cheap amazon micro phone cable if you want - play at your own risk. If your steering wheel goes limp after a short to this port - please don't' try to fix/reverse it.

Please 3rd party vendors - leave this port alone and continue to use the data/power port behind the lower passenger's kick panel. - Its safe to both opens and shorts and good for data snooping.

But - do what you want.

I did not say anything about messing with this port. Nor did my description of the Etherloop have anything to do with it.
Etherloop should be protected against both comm shorts and opens, since hopefully the CW and CCW ports are independent.

Very strange that the telematics module can take out steer by wire though.

Who designed a micro-usb port in the ceiling that can brick your car or disable its only steering mechanism? Maybe the same guy who worked on the Death Star project for the empire?

i would like to see some talented people working on this port. Maybe connect a WiFi AP to it.

this site claims it just provides 12v power and is an a2b audio bus?

It gets power (probably 12V) from the MCU/ Gateway.
