I had my uncle run his computer to c if I can get some codes on the reason why the epc light comes on. All he was able to get was this 46 central control v. I have no idea what that is can it b connected to the epc light?? Any help will do thank you
Well, there should be a specific code; that the scanner gives you, after the scanning process is done. We can look up a code; the description, doesn't tell us much by itself. Otherwise, take it to a parts store; have them scan it for you and see what the codes are, typically they will do this for free.
For trouble shooting long term; you should consider getting your own scan tool.
There are a number of apps for scanning; I use Dashcommand on my iPhone but you also need a wifi ELM 327 OBD II adapter. You can purchase these on Amazon.com; make sure to buy a Wifi version (iOS Apple) not a Bluetooth version (Android).
There are other apps that maybe better but I have been using Dash Command by Palmer Performance:
