Reset The SES Light With A Scanner
This method is a little bit easier, as the scanner comes in handy.
Procuring one is not hard, but it still requires time and some money.
First of all, take a seat behind the wheel.
You bought a Code Scanner and you’ll want to use it, so where to insert it?
It goes in the board port. Locate the steering wheel.
The specific port it’s to its left. Have you discovered it?
Now, insert the code scanner into the port. Insert the car key and turn it.
Your instinct will tell you to start the car, but that won’t help at all.
Simply turn the key, without going all the way, so the control panel will lighten up.
Before starting, examine your tool: the scanner. It is going to be your best friend.
For the beginning, search for a button that will enable reading the codes.
When you press it, the scanner will start displaying all of the codes, so you can work with them later.
They’ve all been formatted.
That means instead of spelling out the errors by their name, the codes will show a letter and four letters (example: P0905).
Write down the codes, as you’ll have to compare them later to a code sheet.
Nowadays, everything can be found online.
After comparing the sheets, the next part is fixing all the errors.
Lucky for you, they are all pointed out by the scanner, so your job is not that hard and it won’t take too long.
Turn the car key again, just like you were starting the car, but don’t go all the way.
To clear the codes and restart the computer, search for the button on the scanner that will enable erasing.

Simple as that. Observe how the SES light is now gone.
You did it. If not, repeat the process, practice makes perfect.

This is how you can turn off the light yourself, without any additional help.
You only need your skills and a Nissan with some technical errors that were, hopefully, resolved.
It requires more patience and effort, but it’s the DIY way to do it.
Take a seat behind the wheel. Although it may seem obvious, it is always better to be safe than sorry.
Find your engine key, insert and turn it, but remember not to start the car, as described earlier.
So, don’t rotate the key all the way.
Simply wait a couple of moments and get ready for the next steps.
Five times fully lower and let go of the accelerator pedal, then let the pedal up.
When it comes to performing this easy motion, timing is everything.

The next step involves your patience and attention skills.
Count the flashes to keep track of all of the codes.
There are 2 different types of blinks: long (0.5 seconds) and short ones (0.3 seconds).
The process of reading ECU codes will be described later in the article, in the section: How to read ECU codes from SES light blinks.
Now it’s the moment to compare your codes with an official code sheet you can find online.
If you want to properly reset the computer, you must first identify and fix all of the problems.
After all the issues were solved, and you’re sure that the codes look fine, reset the computer.
How do you know you are ready to reset? The ECM is indicating no malfunction when you get four blinks of 10.
In the car’s language, this is code 0000. Turn the car key again, until the board lightens up.
Maintain the accelerator pedal down for ten seconds as the codes are blinking and easily let it go for ten seconds.
The SES light should be now turned off permanently.
If that doesn’t work, try again, making sure to follow all of the procedures and wait the precise length of time.
That’s all. Try the method that fits you best and enjoy a clean board, without any Service Engine Soon light popping up.
Warnings Before You Turn Off The SES Light On Your Nissan
Now you know how to turn off the Service Engine Soon light on Nissan, but wise people are never in a hurry.
Consider these warnings before putting the tutorial into action.
The SES light is not there to confuse you, it’s there to point out something is wrong with your Nissan, so NEVER turn it off without resolving the issue. Look for these:
01. Service Due
Sometimes, your vehicle only informs you that it’s time for a routine service check.
This can mean your engine oil needs to be changed, or other minor technical problems, like the necessity for new spark plugs.
Nissan is an amazing car, treat it well and it will get you far.
02. Engine Fluids
Take into consideration the level of your engine fluids.
A low level can also be a trigger for the SES light.
03. Diesel Filter
If your Nissan is younger than ten years and runs on diesel, then the need for a diesel particulate filter renewal might be the issue that’s turning on the SES light.
04. Loose gas cap
This is a common reason why the Service Engine Soon light illuminates.
If you just had a gas tank refill, and the cap was not returned into position correctly, it can become loose and become a possible threat for your Nissan.
This problem has an easy fix, and won’t require a manual reset of the SES light.
Move the cap position, on and off, then drive for a few minutes. The light will reset on its own.
If you want to attempt the DIY way of turning off the Service Engine Soon Light, you must learn how to read ECU codes.
In summary, the SES light will start flashing error codes that are stored in the system, and without a code scanner, you have to be the one to read them.
Firstly, count how many flashes you see.
The blinks show a 4 digits code.
A long flash (about 0.6 seconds) points out the first digit of the code.
It is followed by three short flashes (about 0.3 seconds) that are the next digits of your code.
There will be a 0.1-second break between the digits, so you can distinguish them.
Keep in mind that 10 blinks indicate the digit “0”.
The ECM is indicating no malfunction when you get four blinks of 10 (0000).
Here is an example of a blinking sequence: 10 slow flashes, 0.1 seconds break, 5 quick flashes, 0.1 seconds break, 10 more quick flashes, 0.1 seconds break, and 7 quick flashes.
This sequence corresponds to the engine code: P0507.
Remember that you can also erase everything. Just push the gas pedal and maintain it there for ten seconds.
