JackFletcher Posted May 21, 2019 Share Posted May 21, 2019 Had the 01 Initial Start A/T code today when I was figuring out my new OBD scanner. Anyone know what this means? There is pretty vague information on google but it sounds like a electrical issue. Any suggestions? Link to comment Share on other sites More sharing options...
JackFletcher Posted May 24, 2019 Author Share Posted May 24, 2019 Update: I found some info in a Maxima Forum. It sounds like the code is due to the A/T control unit not getting enough voltage. I replaced my battery yesterday just cause I needed a new one, we’ll see if that does anything but I doubt it. On another note, I saw this plug going into my transmission and it is near where my rear main seal is about to go out. I was hoping you guys could tell me what that plug is for and maybe if it could have something to do with the control unit. Thank you.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Having low battery voltage can throw all kinds of strange codes so that really could have been the issue. 1 Link to comment Share on other sites More sharing options...
Slartibartfast Posted May 25, 2019 Share Posted May 25, 2019 If it's just a low-voltage code, I'd just clear it and see if it comes back. The ECU might've just gotten pissed off when you replaced the battery. 1 Link to comment Share on other sites More sharing options...
