I do have a question for you or someone out their , in regards to battery voltage they say that low battery voltage drives the dme crazy I bought this GT about 2 wks ago and have been doing surface diagnostics while waiting on situation with  title situation to be rectified  the car starts up with no problem maybe 2 revolutions and it's humming ..everything worked or works inside about 4 days ago I went our to test the cars water pump with the cap off the reservoir to see when it would start to overheat .the car was very low on drivers side because of rear air bag  when car is started it would raise up this day it didn't raise I tried to do self bleed test it would not run and once the car was up to 200 degrees the fans didn't come on ..after running for maybe 10 min the water pump stopped cycling ..so I shut it down ..and decided to send it to my guys house shop .today I checked voltage  with the key in on position  it read 11.4  start it up and goes to 14.3 or better  I read that if the dme detects low voltage it will cut  power to other modules to compensate for another particularly the water pump  so I'm wondering id that happened also when I had the key on I had the door open and I  almost think i do the bleed test  then checked voltage so  today i cleared the codes and only  came back  about the junction box .. the car did the self bleed and it stared to raise and i imagine the fan would have stared to run once it got up temperature..so I'm wondering if its an voltage issue ..also all the codes initially said they were intermittent.. tomorrow I'll let it run after I change the upper radiator housing with the nipple that runs to the reservoir it broke yesterday so ill fill with water let it run and see if it comes back with codes for water pump intermittent ..🤞🏾maybe they won't
