I have recently been in touch with Peake Research regarding my scan tool. I had used it recently and was not able to find the code on the table that they stated it would be on in my manual. Through speaking with their department and providing them with my last 7 VIN they stated that a new code table that had not yet been published was coming out. As such they provided me with the new code table for our cars (at least for my car 3.8l).
The code that I had shows up on the table (1A Control unit supply). Seems the vehicle noticed that my battery had been unplugged and the DME was not getting power.
Here is the table for anyone else that uses the tool, or is thinking of getting one. This table (K8) seems to be accurate now.
