I have a Mitsubishi L200 Triton ml 4M41 truck. It's a 2006 model. In this video, I'll show you
how I use my G-SCAN 2 car programmer to do Small Injection Quantity Learning. In order to do that
I have to take the car for short drive first in order to get a few parameters like the engine
& the radiator temperature at the required specifications. So join me in this video as
I show you how it's done with the G-SCAN 2. In the manual. Mitsubishi say that Small Injection
Quantity Learning is required when you change the ECU or when you change the injectors. I believe
there are actually other components which trigger the need to do Small Injection Quantity Learning.
For instance, when you disconnect the battery, the ECU loses its fuel trim settings. Therefore
you have to do a Small Injection Quantity Learning when you change the suction control valve. You have
to do the Small Injection Quantity Learning because the system has changed. The performance has
changed. So anything in the fuel supply, & the combustion system that changes, you should do a
Small Injection Quantity Learning. In the user's manual, it states that every service interval, you
have to do the Small Injection Quantity Learning. Because in doing that, the ECU can learn &
adjust for the characteristics of each individual injector in order to optimize its performance. So
join me in this video as I carry out the process. So I'm in my car. I've started the engine. I'm
going to take it for a short drive. I just need to drive it long enough so that the engine coolant
temperature is between 80 to 90 degrees Celsius. The transmission fluid temperature about 60 degrees
or higher. And then when I come back home , I'll be able to begin the process. And turn off all
accessory power. Put transmission in neutral. I've taken the car for about 10 minute drive. Just
to show you the temperature. It's on the middle & I'll see if I can start the test now. So here's my
G=SCAN 2 programmer. So it uses an OBD2 connector to connect to the car ECU, & it uses a computer
parallel-port to connect to the programmer. So I'm going to connect to the car ECU first - there.
Now I'll connect to the parallel-port of the programmer. Make sure you line up correctly
because the pins in the parallel-port are very fragile, & can bend easily.
Turn on the programmer.
I haven't updated my subscription - just saving money. I've now turned the car electrical system
to ON, but I haven't started the engine. I'm going to select Diagnosis. Choose Mitsubishi.
Use Automatic Selection.
It recognizes my truck Triton or L200 series. Click OK.
It's now scanning the Subsystems for any Diagnostic Trouble Code (DTC) errors.
There's 17 Subsystems to scan. It's now at number 4 of 17.
5 of 17. It's a slow process.
12 of 17.
We're nearly finished 17 of 17. I have the car engine on idle.
I'll select this to start.
I want to go to Special Function here.
And under Special Function, there's a few things including DPF Regeneration.
Injector Code Registration. But I want to go to Learning.
Press F1 for Small Injection Quantity Learning.
It asks me to make sure that those parameters are okay. I'm going to try.
It's starting. So the parameters must have been satisfied. Now listen to the engine change.
It's completed. So I hope you saw all that. It did adjustments for each injector. It changed the
RPM in order to learn the behavior at different RPMs. So now it's completed. I can click .
It's finished. . If I just go into that code.
So this is really just the CANBUS communications.
I'll erase it. I don't think it's important. Let's see what this one is.
Again this is CANBUS communication. So I'm just going to clear them.
I'm going to exit. That's it. It's finished.
By the way. As you can see this G-SCAN tool is incredible because it takes in
a large range of manufacturers. European; even local Australian manufacturers (Holden & Ford).
An Japanese, Korean. So it is certainly more cost effective than buying just a Mitsubishi
programming kit, or one for Volkswagen only. So this is a fantastic tool, & it's a professional tool.
