Okay, then you're left with replacing the Evap assembly. From the looks of it there is probably dirt and dust from the road in it. You can try checking for batter voltage on this Black wire with the Key On, but the system might be disabled with codes stored in the computer. Besides that, i don't have any more for you. One of our databases for vehicle information is down. Plus, you would need a high-end scan tool to bi-directional operate any of those components. Also, this is an integrated component, so you might want to get it from the dealership. Write the codes down and bring them with you also in case they have any additional questions for you. But if you didn't find any wiring problems to the canister, it appears to be a failure.

What other codes are you getting with the traction control light, brake light, 4wd light and check engine light on? You may have codes stored in the ABS module. You will need a scan tool that can scan other modules in the vehicle besides the engine computer. It needs a full system scan done. You're sure you didn't damage any wire while putting the Evap Canister back in? The rear driver side ABS sensor wiring, and the Skid control wiring run back there.

No, that is only a basic global OBD2 scan tool, it will only scan the engine computer. There are most likely codes stored in the ABS module, it's not good that your brake light is on. Plus, every other light. It's kind of strange all those lights came on right after you put the Canister back in. You need to check the wiring to rear wheel speed sensor and the Skid sensor back on whatever side the canister is on. And make sure nothing came unplugged. None of those lights were on before.

The size of the car tires has been changed for a variable size than the required size according to the manufacturer's instructions. The tires currently installed above the car are 245/65R17 111H.

Right Size 225/65R17 101H. Could this be the reason for the appearance of Trac and 4wd codes?

No brake code.
The signal was visible because I used to apply the parking brake while I was stopping the car.

The light can be on due to low brake fluid in the Brake Master cylinder, the Parking brake is stuck on, some kind of issue with the Skid control unit. I can see the wrong size tires shutting off the traction control or Skid control, but the Brake light itself being on. Did you recently change the tires, because none of those lights were on in any of your other pictures? And if there were any Brake related codes, they would be stored in the ABS module.

I bought this car a year ago from a friend of mine and my friend changed the car tires before he sold it to me. The car has been with me for about a year, and these signs are on the dashboard, the 4wd and track codes.

So, you drove this for about a year and then the warning lights came on? So, it's probably not due to the tires, plus you have the 4 Evap codes stored in the Engine computer still, correct?

I bought the car a year ago, and the signs on the dashboard have been around for a year. The check code, the tractor code and the 4WD were there a year ago.

This picture was taken today when I filled up the car at the station with 20 liters gasoline.

Counter number 163 mpg, the total consumption of the car is 40 liters gasoline.

The 163 is only the Trip Mileage counter, I'm looking at the 15.1 MPG, which depends on if its city driving or highway type driving. Because there was a fault in the Evap system the engine computer adapted and learned a new fuel strategy to stay as close as possible to emissions standards. Now if the codes stored in the engine computer are labelled "Historical" that means the engine computer is not seeing that fault currently. And your gas mileage is getting better. When you were at about 40 miles on the Trip counter, you were at about 12 MPG, now you're at 15 MPG. So, if that stuck vent valve was the issue, and that fault is not occurring anymore, the engine computer is slowly relearning its fuel strategy and its improving. The scan tool app you're using doesn't have the ability to clear out the memory to where the engine computer would be learning from a default type of state, like when the vehicle was first bought. If everything is ok with the Evap system, the codes will eventually disappear after it runs enough of its self-tests. This car should average about 21mpg during the city, stop and go type driving. If the codes are still there and are current, then the Evap assembly is most likely at fault and needs to be replaced. Is that what you are wondering?

Historical Faults are not currently happening. Are there any Faults that are current? There isn't anything to look up with the VIN number. I have the vehicle information. Without live data or any data is hard to say if there's anything else wrong.
