Good find, Mods please make this a sticky.

 

OK I tried this.

The first two times, I went through the procedure and nothing happened.

So I then started the engine and let it run for a couple of minutes. I had not previously started the truck today.

I then tried the procedure again and it worked on the 3rd try.

I don't know if maybe I didn't do it exactly right the first time or if the code was not stored again until I ran the truck. But if it's not working for you, try starting the vehicle.

 

I get the following.

1 long flash
2 short flashes
1 long flash
2 short flashes

Then

1 long flash
10 short flashes
10 short flashes
10 short flashes.

So I am guessing I have multiple error codes?

1212 sounds like my ABS is shot
and
1000 is not listed on either of those sites...

SES light comes back on from reset, before I even start the car.

 

This is a very good thing to cut, paste, print, and carry in the truck... I reset mine after adding any mods that effect the engine output, and probably will do it after every service, just to make sure the ECU recalibrates itself... My engine's sound and response seemed to be very noticiable after the first time I reset the ECU, but it may have just been wishful thinking, anyhow I thought it was improvement after mods added...

 

2006 Titan, Tried it. No go for me. I went to my local Pep Boys. Picked up an ODB II read and reset tester, $75.00. Read the code, reset the code. I had an exhaust leak on the front side of my muffler that caused the MFA sensor to trigger. Then I proceeded to help others with their lights. Made some new friends. Never realized how many people had service lights on in their vehicles. The best part is I wasn't without my vehicle for a whole day.

 

There is another way to do it. It is on a sticky thread I do believe. Posted way back when. It worked great for me. I think there is actually a couple of threads posted about.

You might want to sift through the whole thread. Some good info in it.

Could you please post a link of the tester you bought??.....I did a quick Google search and most are costing at least a couple hundred bucks...
ThanX

Here is a link to the 1 I use, What's nice about it is it has a code library built in, Also you can watch all of the function's real time as your running the engine. I paid $139.99 @ Autozone for it. They have mini code reader's starting @ $59.00.

I was getting "service engine soon" light after I started my truck with the IAT sensor disconnected. After several attempts to reset the connector and battery failed, I tried the steps posted above and they worked for me. Light flashed and gave me the 0113 IAT sensor. I started the truck immediately after and the code went away. -The manual states the code should go away on it's own after the problem is fixed(*IAT sensor for me), but after several trips the light was still there. Resetting the ECU solved the problem

Thanks!

 

-So the light came back after I restarted my truck once again. Sucks! Well, Kept working on it and I found some info. I Think steps 5-8 did the trick. h__p://_ww.350z-tech.com/zwiki/Tutorial:ECU_Reset
Manual Method
Here is a quick way to reset your ECU. It is also known to clear codes thrown, and turn off the "Service Engine Soon" Light. It's a little tricky, but works.

Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
Repeat the following two procedures quickly five times within 5 seconds:
Fully depress the accelerator pedal (HARD).
Fully release the accelerator pedal.
Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
Fully release the accelerator pedal (while the CEL is still blinking)
Wait about 10 seconds.
Fully depress the accelerator pedal and keep it for more than 10 seconds.
Fully release the accelerator pedal (The CEL light will continue to blink).
Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.

 

Thanks. I tried this and it gave me the 0455 code. I tightened the gas cap and reset the code. The light went out and has not come back on. You saved me a trip to the dealership, not to mention the $85 they charge to run the diagnostic.

 

Hi:
I found this site two days ago and have enjoyed looking around on it. I came here because of my truck 2004 high miles) was idling at lights rough. My friend helped my to clean the throttle body. Thi fixed the problem. By the time I got home I had a SES light. Came here saw the resets. Did them light gone. Drove to work light back. Now the truck idles high when in park. Went to autozone , error code is P0507 Idle Control System high idle. Spoke with my buddy, says find out if there is/where it is/how much a air intake control motor? So, any other suggestions on this proble to make the SES go away and have the truck idle properly? Thanks for the help.
Matt

 

if you need an obd11 check engine light read any autozone can check it out in the parking lot and print the code for you inside with some probable causes on the print out.

 

Just subscribing.

 

CAN SOMEONE PLEASE HELP im new here, and my truck hasnt been able to start for this past week. It cranks, just doest start, i didnt know where to start. Well finally i get my hands on a code reader today and the code is p0113 (iat circuit high output). reading some threads, i find out that the iat is included with the maf. could this be the reason why it doesnt start? it first cut off on me while i was goin around 60mph, but it started right up, until the next morning. Doesnt start. please help, somebody, anybody, i miss her. thanks

 

i tried doing all these thing on my truck and the light woulnt turn off, i was going to take the truck in to the dealer to get checked out when it started making a noise like it was going to turn off on me, turns out its the gas pump! $700 to get fixed plus other little things

 

i kind of had the same problem and to tell you the truth i hope its not the same thing, one of the computers on the truck had burned out and it had the same symptoms. i paid like $600 to get it fixed at the dealer. you should take it in to get checked out befor something else goes wrong and then you end up paying alot more money.

 

I recently purchased a new Nissan Altima for my wife. After some research I found this procedure for the Altima. Resetting and diagnosing ECM diagnostics codes problems.
www.nissantalk.com
I decided to use this procedure on my Titan. I left the gas cap loose, after an hour of diving the (SES) light was on. (Nothing like the glow of the SES light to raise your blood pressure) I used the below procedure and read the code of (0455); the ECM is indicating evaporative emission system leak detected. I retightened the gas cap and cleared the code. Use this procedure next time instead of disconnecting the battery cable.

ECM Diagnostics/ECM Reset procedure:

1) Sit in the driver's seat.
2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)
3) Fully depress and release the accelerator pedal five times in less than five seconds.
4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the SES light flashes.
5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.

Long flashes (0.6 seconds) indicate the first digit of the code; count the blinks one through nine and write down the first digit. (Ten blinks indicates zero.)
The next three digits follow in turn in the same fashion except with faster blinks (0.3 second) and a 1.0-second pause between digits.

The ECM code repeats itself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard get-in-and-drive-mode.
Additionally, if you get four blinks of ten (0000), the ECM is indicating no malfunction.
You can look up the trouble codes at
Infinitihelp.com
Or
http://www.iequus.com/obd_def.asp
You need to add the letter P to the four-digit code.
You can clear the code (and the annoying SES light) by holding down the accelerator pedal for more than 10 seconds while the SES light is blinking. When you release the pedal and turn ignition off the ECM erases the trouble code(s).

A built in code reader is definitely a plus on any vehicle. If this works the Altima and Titans it probably works on other late model Nissans.

Has anyone else used this procedure?

Thanks so much for this info. I have a 2004 Maxima and it worked great for a code of P0340! You saved us alot of money!!!

 

came up with a code of 1203 where can I find out what this is?

 

Are you sure it's 1203? I can't find that in my 06 factory service manual. I did find this "P1203 Injector Circuit Open / Shorted - Cylinder #3 " under generic P codes at this website.

If it's a b code, the generic is this "B1203 Fuel Sender Circuit Short To Battery." Generic c code "C1203 ABS Outlet Valve Coil Rear Circuit Open."

What are you using to retrieve the code?

 

the first 2 links are not working.

 

how do u know if it is a p b, or c code. I used the cel to get the code. called nissan and they told me they did not have a tech avaiable to tel me lol. called autozone and they said it was teh throttle postioning. so I reset the ecu and the throttle postioning. So I will see if it happens again

 

I'm not sure if you can tell by counting the flashes. I use either Cipher or an Actron code reader. Usually AutoZone and others will come outside and read the codes for you directly from the vehicle for free, if you can get your truck there. The codes are four digit numbers preceded by a letter, which is usually P but can be B or C.

Hopefully it was not a real problem and won't come back.

 

autozone's scanner kept coming up error. I reset the light and the throttle postioning and pulled my camper today 40 mi and no light lol, we will see

 

hey all those with SES lights on or had them on. I just wanted to share my experience with having the SES light come on in my 05 Titan LE. Took it to the stealership today and they said it was the control valve sensor that is located underneath the truck in the very back, almost by the exhaust. That little baby cost me 148 dollars (Canadian) and a half hour to replace it. They took two hours diagnosing the truck and seeing what is causing the light to come on. While he was underneath the truck he noticed the seal of my transmission casing is bad and it's leaking transmission fluid slowly. That sucks. So I'm waiting for that part to come in and will take it elsewhere to install it at a much cheaper rate/hour.

 

Bumping an old thread....

I'm getting 5 long flashes no short ones.....what is that?

 

Bump Reset does not work on a 2004.
