Hey guys,
My 2015 BRZ (11,000 miles) threw check engine light U0074 last night. Did not notice it run any differently. It was my second day with a Bluetooth OBDII reader running the Torque app on my tablet. I disconnected the OBDII sensor after reading the code and it did not disappear. The next day it was gone without me having to clear it.

Code U0074
"Control Module Communication Bus "B" Off"

Do you think that the OBDII reader caused this or know any more information about the code? I used torque to read the code as soon as it happened.
