Once you plug in the scan tool, you will get two options or two submenus to choose from, one for the ECU and one for the TCM. Then, you pick which system you want to diagnose transmission or engine , and as soon as you select one of the two, you will get a fault code readout just like you normally would.

The 7EA code can be triggered by a variety of factors, ranging from minor glitches to more serious underlying issues. Could be an O2 sensor though. Thanks everyone.
