The FIRST thing you need to do is ERASE (CLEAR) all these codes from the computer and see if any return.

Re-enter diagnostics and when you get to the .7.0

Simultaneously push and hold the OFF and HI button on the panel until you see .0.0 and release the buttons and turn the ignition key OFF..

Wait 3 minutes, Turn the ignition key ON and re-enter diagnostics and see which codes reapper and how many times each code appears.
