When I turn off the park mode, this alarm appears (immobilizer).
Since the engine's alarm has been displayed, the previous alarms (transmission.) Were not displayed.

Welcome back:

You know, about a year ago I went through a very similar situation on the same type of vehicle. I hate to say it, but if I recall correctly, the PCM had failed.

If I warm my car in P mode for a few minutes, then no alarms appear.

I think A/T case inhibitor switch has problem.
Because by shift lever change at several times, the alarm did not appear.

Dear,
Could you please send to me exploded drawing for CVT gear box?
In start up less than 5 km/h gear box has noise, and after 5 km/h, its normal.

Welcome back:

I attached all components and the legends with descriptions. First you will see a picture. The legend which follows each picture correlates with the picture.

Let me know if you have other questions.

Thanks. The sound comes from the four wheel side(4WD part:from drive end )
The rear section of the gearbox.

One question: how to test sensors with digital multi-meter? For example O2 sensor, speed sensor, CVT sensors and etc. I need methods and data sheet for sensor test. Thanks

For example; I tested the sensor on the upper part of the gearbox, but did not show any value.

Welcome back:

Most all sensors are checked by testing for resistance. Here is a link that shows how to use a multi meter:

https://www.2carpros.com/articles/how-to-check-wiring

What sensor in particular do you want to test? There are sensors everywhere. lol Also, is there any way you could record the noise and upload it? I would be more than likely able to tell if it is from a sensor or not.

Welcome back:

I have attached information for testing all sensors / switches related to the CVT transmission. The first two are related to the shifter switch. Pictures 3, 4, and 5 are for the range sensor. The next 4 pics are related to speed sensors and provide locations. The last three pics are for the CVT temp sensor. Here are the directions for testing.
_________________________

TRANSMISSION FLUID TEMPERATURE SENSOR CHECK

pic 6

1. While pressing A in the figure, turn B counterclockwise to unlock the CVT assembly connector, and disconnect the connector.

Pic 7

2.
CAUTION:
Insert a thermometer which is made of metal or is put in a metal case (overall length: approximately 150 - 200 mm) into the transaxle case hole approximately 80 mm.

Remove the oil filler tube assembly (Refer to Transaxle Assembly), and insert a thermometer into the transaxle case hole.
NOTE:
If a radiation thermometer (noncontact thermometer) is available, use it to measure the surface temperature of the oil pan.

3. Measure the resistance between the sensor-side connector terminal No.17 of the CVT assembly connector and ground (terminal No.19).
Standard value:

pic 8

NOTE:
In the information screen on the multi-information display, the fluid temperature warning comes on when the transmission fluid temperature is approximately 140 C (284 F) or higher, and automatically goes out when the transmission fluid temperature dropped below approximately 137 C (279 F).

4.
CAUTION:
The transmission fluid temperature sensor cannot be removed or replaced as a single unit. When the transmission fluid temperature sensor needs to be replaced, replace the valve body assembly.

When the resistance of the transmission fluid temperature sensor is outside the standard value, and the fluid temperature warning comes on/goes out at other than the specified temperatures, replace the valve body assembly and the harness.

Let me know if they help.
