This block diagram is most likely suitable for most 4-cylinder engines with a mass air flow sensor (MAF). Ideally, you need to find such a block diagram specifically for your car model. It is in the original manual (ec.pdf file).
For V-twin engines the block diagram is very similar, the main difference being that the engine consists of two parts (left and right). One side is designated B1 (Bank 1), the other B2 (Bank 2), and you need to check each side separately.
Below you will find a detailed description of each of the steps in this flowchart.

DETAILED PROCEDURE
Step 1.

-Mode for checking the operation of the idle air valve (IAC), if present in the car.
-Mode for checking the operation of the first narrow-band oxygen sensor, if this mode is not displayed, then most likely your car uses a wide-band oxygen sensor.
-Learning mode for the zero position of the gas pedal - the mode is available for cars with an electronic gas pedal.
-Learning mode for fully closed throttle position - the mode is available for cars with an electric throttle.

The help is fully translated into English.
Many things have been fixed.
If you have a desire to improve the translation - write, we will correct it.

- added Power Balance Test (to find faulty cylinders).
- for NC1, a fuel trim reset mode has been added (previously it worked through active tests).
