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.
