• Yamaha Motorcycles Service Repair Manuals.

To enter the diagnostic mode and check existing error codes in the system memory, do the following:

1. Turn off the ignition, put the stop engine button in the ON position.
2. Disconnect the fuel pump connector.
3. Press the SELECT + RESET buttons on the dashboard at the same time and do not release.
4. Turn on the ignition (we still hold the buttons) and wait ~ 8 seconds until “dIAG” appears on the dashboard.
5. Release the buttons, use the SELECT button to select “dIAG” (for the case if another text appears on the dashboard).
6. After dIAG is displayed on the screen, press both buttons on the dashboard (SELECT + RESET) for ~ 2 seconds.
7. After the diagnostic mode (d01) is displayed on the dashboard, turn off the stop engine button.
8. You need to move through the list from d01 to d64 using the SELECT (up in the list) or RESET (down in the list) buttons.

In the list range from d01 to d59, a self-diagnosis of the system components is carried out.

Inclusion of some components is carried out by the stop engine button.

8. View the room opposite d61. This is the error number IN MEMORY of "brains." If there are several errors, they are displayed alternately.

All diagnostic cells are above 60 - and there are diagnostic lines for each of the components separately. More details - see BELOW.

To erase the error from the system’s memory, go to line d62 and turn on the stop engine button on the right remote control.

In detail:

• Pressing the Select (upper) button, you need to go to the indicator [d60] (real-time self-diagnosis) and [d61] (error memory) and see the number next to it. The number nearby is the number of the error that the brain remembered.
• And all other numbers from [d01] to [d60] are indicators of various sensors (for example, [d01] is the position of the throttle in percent at the moment, twist and you will understand everything).

Er3 = signal error from the engine control unit

Er4 = unknown signal from the engine control unit

Yamaha motorcycles have built-in self-diagnosis.

When the ignition is switched on, the red immobilizer indicator on the dashboard lights up.

By blinking it, you can determine the malfunction.

From the beginning, it blinks slowly five times, this is equal to the first digit of the code. Then quickly, this is the second digit of the code.

Some decryption codes:

5-1 - does not see the chip in the key. Most likely the problem is in the chip.

5-2 - the chip in the key is not from this motorcycle. Most likely you took a chip key from another motorcycle.

5-3 - there is no communication between the engine control unit and the immobilizer unit. Check motorcycle wiring connectors.

5-4 - there is no synchronization between the engine control unit and the immobilizer unit. Entangled block- motor and immo.
