HELP!!
I tried a few times and it just doesn't work.......

Turn key to on, 3sec, step 5 times, wait 7 sec then press until light blinks, but it NEVER blinks.......i mean, for 10 sec, 20 sec, 10 mins and still nothing happens. Tried it over 10 times and the CES light won't blink, what light is the CES anyways??

Anyways, any addition tips would help.

Btw, the car is from Canada, don't know if it make any difference(and I do doubt it), but so far, all those that posted that it works are Americans......
Just that I can't even get pass step 3 on the procedures makes me doubt the possiblity of this working at all........AARGGGHHH!

Anyways, any input would be awesome!
Thanks!

 

Did you use a stop watch? Also, try pressing hard on the accelerator (all the way down to the floor) each time. Make sure you step 5 times within 5 seconds interval. I doubted that the car sold in Canada is any difference electronicwise. This procedure is applicable for all VQ3.5's engine (so I've heard). So keep on trying!

 

that's pimp.. this means it'll work for the 2k-2k1 cars too.. hehehe g' lookin' out man

 

One quick thing,


Before you start the whole procedure you must have the ignition to "OFF" for 10 seconds or more. I find to be a little bit slow or a tiny bit lazy with the time works best. If you're too fast it will not work at all. I experimented with this a lot before because I have no life.

BTW I'm in Toronto Canada, so it definitely works on our cars.

Good luck,

Did it today and I noticed that the stumble when accelerating is gone. It used to fall on its face for a 1/4 second when you put the peddal down. Now it just goes...yeah! Took me like 5 tries just counting but the CEL lite flashed exactly as the directions said. Thanks!

 

I reset my ECU this way a couple weeks ago..my question is will it be okay to do the "Accelerator Pedal Release Position Learning","Throttle Valve Closed Postion Learning", and "Idle Air Volume Learning" without resetting my ECU again.. or in other words do I have to reset my ECU again before doing the following three??

 

Well, after reading more posts, I tried again and it worked!!!
The difference is unbelieveable!!!

I'm in love with the max all over again! It's pulls much harder and there's an actual difference whether you give it 1/4, 1/2, or full throttle........
I'm a believer now and thanks to all that contributed to this thread!

You guys rock!

 

TitaniuMax,

You can do these procedures without resetting the ECU. It is best to do them in the order you mentioned, as that's what the Service Manual indicates. Though I have an Alty, it's the same exact thing, and I've used the Alty manual to troubleshoot my buddy's 2k2 Max.

Enjoy,

I reseted my ECU today. and I feel like I heve a new car again.

 

Thanks for the tip, I tried this, took a couple of tries, works great.

 

Just to make sure -- resetting the ECU as suggested by this thread would not take the place of having the dealer perform the TSB-suggested ECU modification, would it? Thanks.

 

Hey,

No, it doesn't substitute for the upgrading of the ECU code (by the dealer) for the hesitation/lack of power TSBs. I would highly recommend getting it done, especially for automatics.

OK -- thanks. As someone with a Max with 3K miles who doesn't have an especially close relationship with my dealer's service dept (don't have any relationship, in fact), what do people suggest re having a dealer perform the ECU upgrade? If a dealer refuses to do it free of charge (I haven't yet asked around), what's the max I should consider paying?

Thanks.

 

That should be FREE serivce, mine was! Don't let them feed you any BS. Have the TSB with you when you go in. The TSB even tells them how to file a claim to Nissan for the service.

 

Scott come reset mine, I can't ever get this **** to work.

 

Hey,

This is a free service. Regardless of your relationship with your service department, they should be able to upgrade your ECU for free. The TSB numbers in the U.S. are NTB03-022 and NTB03-023. The 023 is for all with "Lack of Power" while the 022 is for standard Max and Altima 3.5SE for "hesitation on acceleration".

Just get a hold of the TSBs, print them out, and read the symptoms on them. If you use the exact wording on the TSBs to describe the problem, the dealership should offer fixing it.

Regards,

10e

 

lets say you already got the 2 TSBs done for the lack of power and hesitation. is there a point to reset the ECU after i did them?

 

I did all 4 procedures but in the throttle valve closed position learning step it says "Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound." What does this sound like exactly?

 

I think that doing the Throttle Position Learning reset makes a lot of difference. I did all 3 except for that one and didn't notice much difference. After reading the post recommeneding that this be done for a hesitation issue, I did this to mine and definetely noticed a difference. Much smoother shifting and downshifting too. Not the gears shifting but it seems as though the motor adjusts much better then before, along with the hesitation problem being much better. I had the hesitation TSB done on my 6-spd and didn't notice any difference until now.

 

It worked for me-Thanks for the info!

 

I believe the only way for us 2000 Maxima owners to reset our
ECUs is the battery disconnect method. Just disconnect the
negative terminal of your batery for an hour. It takes up to
12 hours of disconnect time on my G35, might need more than
1 hour for the Max. If you disconnect it over night while you are
sleeping, it surley will be reset the next day!

 

I noticed that when I re-did it (as I had done it before the TSB on my 5-speed Altima 3.5) the throttle responds a bit differently. Before it had to seemingly reach a certain position before it would start to accelerate harder (as if it had to reach a certain "step" or a certain point in its downward progression) whereas now it seems to respond almost right away to every little change in my right foot.

Flooring it is no different but the throttle seems a bit more responsive.

What is the difference by using this method http://maxima.theowensfamily.com/reset-ecm.jpg. Haven't tried using either but I feel that my ECU needs to be reset. I would like to get input before trying either one of these.

 

The graphical version of the top post is available at http://maxima.theowensfamily.com/reset-ecm.jpg

This procedure only works for the 2002+ drive-by-wire vehicles. It is the same procedure as the top post listed, just extracted from the Nissan ESM, and will reset the SES/MIL lamp and codes.

-Thanks to me for providing that image

 

p0150n,

There is no difference using that method. That picture is from the service manual that Nissan publishes for the Maxima. The only difference is the fact that it mentions the ten flashes afterwards.

Here's the deal:

If you wait seven seconds and then press the pedal and hold it, and then wait until the SES flashes, it will give you the error codes that the computer stores. Each set of flashes is a number from 0 to 9 (with ten flashes equalling zero) and after four sets, if it flashes ten times each set (ie. between the pauses) that means the error code is 0000.

For example, if your gas cap is loose and your SES light comes on normally, and you check the error (which by the way is 0442), you will see ten flashes, a pause, four flashes, a pause, four flashes, a pause, and then two flashes.

This is useful for troubleshooting why the SES light is on, and if you have a buddy with a service manual, he can tell you the possible causes.

If there is only one error it will repeat it. If there are two, the four sets of flashes will be different.

Regards,

10e

 

Sorry,

I missed the fact that you release the gas pedal after the SES light starts to flash.

Can anyone verify if this is true???

 

Have you added that to the "How-To's" yet?

 

Yes, manually.

Or electronically, you can go to your local autoparts store, use an OBD scanner, or take it up the azz at the dealer.

Your choice.

 

I can't believe that I hadn't already done that... but I didn't. It's added now.

Why can't I be a moderator yo?

 

Thanks!

Want my spot?

 

I just tried this and it seemed to work however the last 10 flashes were kinda slow compared to the first three sets of flashes. Is this normal?

 

If you don't want it, sure, but do I get the penny to go with it? ROTFLMAO

 

Kev picks those and the caption under your name, you don't get a choice.

 

I had a choice....you're just a scrub and almost worthless jk

 

Yeah, but mine was "FREE" along with OT access.

The only catch is I have to put up with all the knuckle heads.

 

where's your buddy NT2SCABBY

 

This really helped me, I noticed a big difference and love the way the car takes off. It took me 3x to get it down right well being honest I didn't use a stopwatch the first 2x. But after doing all the resets, wow the car launches in every gear!!!! Thanks for the post !!!!

 

I think he got banned. Anyone know why? I kinda miss the flames.

 

Hey, I have a 99 ES Max with these problems - any solutions??? Please!!!
