Shimano electric bikes fault codes
Every Shimano electric bikes fault code we have documented, with what it means. Pick yours to see causes, checks and the parts involved.
● 20 codes documented
Shimano uses 20 fault codes on its electric bikes, shown on the display when the machine stops — among them E001, E002, E010, E011, E012. Each one points to a specific part: on this page you find them all, with what they mean.
How to read the code on the display
Every code below comes from a published source, with the manufacturer or motor system stated — never a generic table.
Write the code down before switching off: many machines clear it when unplugged, and without the code the fault has to be found from scratch.
