So I have completely disconnected the hu and taped the two exposed wires I found. So after driving it for a week, about 100 miles no issues. I havent messed with the 4th brake light yet, in order to narrow down the issue.
My next plan is to recconect the head unit as it was instaled to see if the problem was coming from one of those exposed wires. Especially since one was very close to the purple splice, which also had bare coper showing. If this solves the problem, I will then solder that purple splice and hope thats the end of it. Once it is fixed I will then solder the 4th brake light.
Since the dealer ran the codes Im not sure what they used. Will they show up with a normal obd ii reader, or is it a special code reader? I did a normal obdii diagnostic and no codes.
Dose this sound like the correct way to go about this? Anyone have any other suggestions? Thanks for all the help so far.
