Ibro Cehic Updated on June 29, What everyone expects to get when plugging in an OBD2 scanner is a P type fault code, and you will even if you see 7EA first. In older vehicles, especially those with a manual transmission, as soon as you plug in the OBD scan tool and it initializes, you will get a fault code readout. 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. But vehicles with two control modules are common; pretty much all cars with an automatic transmission made after have them. Modern vehicles, on the other hand, can have up to nine different control modules, and scan tools typically have a code for each of them. But ultimately, the initial screen you see on the scan tool just lets you pick which system you want to diagnose first.
