I just read over 40 pages on the topic of resetting your ECU.
At the end of reading everything, It appears there are 4 methods mentioned and one mentioned by a Infiniti tech that most ignored his post. I also noticed that all post were done in 2009. Has there been any new findings on the correct method to reset the ECU.

Method 1 - the gas peddle thing were you press 5x etc wait 10 seconds etc.

Method 2 - disconnect the battery for 12 hours

Method 3 - Disconnect neg battery terminal for 10 min and push break for 30
seconds

Method 4 (Infiniti Tech guy for 13 years) - disconnect positive and neg terminal cables and touch them together for 5 seconds and the ECU is cleared.

So with all these methods, which one is proven to work. Not opinions, are butt dyno feel. Seems like someone can confirm this with Infiniti. The last method (4th) was posted by a Infinti Tech but that is the one that most dismissed. What gives. I am tired of trying to read all the post. Anything new on this? Anything confirmed? And yes I read and searched before I posted.

Thanks for any replies and you time.

 

Method #2 sounds like a winner
I have heard #4 will also work. Apparently the completed circuit (touching terminals) drains all the residual power in the RAM etc and resets everything.

 

I did #3 for several times with a success

 

lol I do a varient of this, Unplug push brake pedal 3 times plug back in, Radio reset, and Mile counter reset, so It must of worked.

 

well actually no, I did not do #3


I did method 2 and 3 combined.

Disconnect Neg terminal for 12 hours and DONE.

That's what I did.

 

#1 is the cleanest way, but #3 is the easiest. ignore the 24 hours / 10 minutes bs...just disconnect the negative terminal, pump the brake pedal 2-3 times, and reconnect the battery after 1-2 mins. i've had to do this so many times i've lost count (don't ask) and guarantee you it doesn't take as long as described above.

btw, when you reset your ECU, there are a few other resets/re-learns you should do. Check the link below for the procedures:

^I want to ask.

Why did you have to reset your ECU so many times?

 

DEFINITELY don't do 4 if you've got a farad capacitor hooked up for your amplifiers....unless you don't mind burning your fingers and welding your battery cables together. In fact, 4 sounds like bad news altogether.

2 and 3 accomplishes the same exact thing but much safer...

 

Well I guess the peddle method would be considered a soft reset and the disconnect the battery and push the peddle would be a hard reset. From what I gathering, the peddle method only resets certain things while the disconnecting the battery and draining the capacitors resets everything (ECU completely).
Thanks for the replies guys

 

I don't think there's any diff at all between pedal method and hard reset method.

 

you are correct. the peddle method doesn't reset everything.

 

You sure? I've done the pedal reset COUNTLESS times. Always with great success as long as you have a clock/watch to measure the seconds.

I've done #2 and #3 successfully as well.

#1 seems to be the best method BUT most people have a tough time getting the timing down.

 

i'm 100% positive.

 

So your positive? If so, what does it NOT reset that a dead battery does? Do you have something to back it up?

 

One last question, I disconnected the battery for 15 mins and then pressed the break peddle a few times for 30 seconds each time. When I reconnected, I did not lose my preset radio stations or blue tooth setup. Shouldn't I have lost all my settings if I was suppose to have cleared my ECU? Seems like everything should have been lost. But then again I know some electronics keeps their settings regardless if power is lost or not.
Sorta like removing the battery from a computer, you do not lose your settings. It this the same with the G?
Now I hate to mention this without solid proof but here goes. When I did the peddle reset yesterday, I felt I lost the snappy throttle response a little. Now I know it takes a little while for the ECU to settle in after a couple of days. Well after doing the battery disconnect today at lunch time, it seems I got the snappy throttle back again (which is good)! Like I said, I have no hard numbers or proof. Just feeling the G out.
