Yamaha error 62: Motor fault

What it means

The drive unit has detected a motor fault and stopped assist. The display alternates the code with 'MOTOR PWR OFF/ON', which tells you to turn the power off and on. The code is stored for the dealer.

Likely causes

• Motor or motor wiring fault
• Temporary electronic fault

Symptoms

• 'MOTOR PWR OFF/ON' and code 62 on the display
• Assist stops
• Red flashing assist lamps on LED displays

How to fix it

1. Stop in a safe place.
2. Turn the display power off, wait a few seconds, then turn it on again.
3. If the code comes back, stop using assist and have the bike checked by a Yamaha e-bike dealer. Do not open the drive unit or battery.
