Well, I just figuired I get an exact diagram from Nissan for procedures to reset the ECU.

I got this from my old online course I had to take.

If this pic is a repost, Sorry.

 

Nissan University lol

 

Im telling you disconnect the batter for 24 hours and all is lost.

 

That's awesome, I love the graph. Thanks man!

 

sticky!

 

Kool, It's stickied

 

NO . . .

 

That was posted somewhere on another thread a few years back. But it's really hard to find, so it's useful to re-post.

 

That picture it says it's the method of Erasing DTC's. What does "DTC" stand for?

 

Diagnostic trouble codes... AKA Check engine lights, service engine lights ect.

 

So does this process only erase any trouble codes? Can somebody clarify how this resets the car's learning to provide better engine response with the new mods.

 

It's supposed to reset the trouble codes and the ECU back to base values which may or may not be a good thing. If you've been "grannying" your car with conservative driving, it can bring back a bit of pep in performance. If you've been driving aggressively, it may make your car feel relatively sluggish.

Try it and decide for yourself to see if your car/driving style justify the few minutes it takes to do on a regular basis.

 

My car seems to be drinking fuel as if it was free after the ECU reset? How long would it take for it to get back to the normal MPG?

 

Some others have reported this as well, especially if you've been "grannying" the car previously. It usually takes only a few days for the ECU to re-adjust.

 

what is the benefit of resetting the ECU?
