DIY: Easy Way to Reset ECU without battery disconnect
A mod or admin should update the first post with the correct instructions.
There's a difference between "within 3 seconds" and "wait 3 seconds" in step one. I bet that's why so many people were unable to get this to work.

True, and there seems to be merit in warming the engine to normal operating temperature, and turning off the A/C, radio -all electrical. Don't press the brake, either. And use a watch or stopwatch because most folks can't estimate seconds, especially when under pressure to do so.
I did this the other day and it took me about 10 tries.
The problem most folks have is not waiting the full 7 seven seconds. I timed it with a second hand and when I stretched it to 8-9 seconds, it worked.

I was able to do this after several tries. For me, after the 7 second wait, I had to depress the gas pedal the entire time the SES light was blinking slow, then it started blinking fast. Does this procedure vary by vehicle year/model? Just from my reading, at the beginning of this thread is one procedure, then reading through the thread someone else had a procedure. Reading the FSM, it's a different procedure. I mean the first few steps are all the same, but after that they're different. I even did something completely different. I was just curious.
Hi all,
I've just got a pre-owned 2010 G37 sedan and I feel the transmission lag.
If I have done the ECU reset, do I still need to do Accelerator Pedal Release Position Learning, Throttle Valve Closed Position Learning, and Idle Air Volume Learning (Throttle Position Learning) procedure also?
Thanks for the help.

Check the last 20 pages of this thread - there is a new ITB out that addresses the sluggish 7AT on the 20-11 models.

I took a large analogue clock to the car and got this to work first time......
Unfortunately it then showed up EVERY complaint that is listed for my car here in the forums.
It's scheduled to go in to dealer on Monday for TSB updates and they are checking the TC and will replace it under warranty if necessary.

Not to rain on anyone's parade, here, but is there any hard, empirical data to indicate that resetting the ECU does anything, at all? Again, not seat of the pants, as that's a useless measure of anything as subtle as this would be.
The main reason I ask, is that my understanding is that the ECU on this (or any modern car, for that matter) is continually modulating and updating the data it processes, based on current driving conditions. We're talking about milliseconds, and seconds worth of evolving data. It doesn't compile days, weeks & months worth of information. That would provide no advantage to the car's control systems.
Quite fundamentally, THAT is the whole reason that modern cars even have the digital ECU systems, so that the engine and associated systems can nearly instantaneously monitor what is happening, and adjust as needed.

Oliveview, good question. I've wondered the same. Infiniti has effectively stated the car learns how you drive, that implies more than a few seconds of data. Heck, I drive differently day to day, sometimes minute by minute. I don't want an average.
