Risk level

Medium

Proceed carefully and stop if the check is unclear.

Urgency

High

Quick answer

On Shimano STEPS e-bikes, error E010 means an abnormality was detected in the drive unit and cuts off pedal assistance; stop riding and restart with the battery power button. If the code remains after turning power back on, visit an authorized dealer for E-TUBE PROJECT diagnostics.

Safety first

Stop and check this first

  • Never disassemble or modify the drive unit or the lithium-ion battery: Shimano warns that doing so can cause serious injury, leakage, overheating, bursting, or fire.
  • Do not touch the drive unit case right after continuous riding, because its surface becomes hot and can cause burns.

Safe checks you can perform

  • Stop riding safely and confirm the code on the display
  • Turn the battery power off and back on again
  • Remove the battery from the holder and reinstall it dry

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Read five-digit subcodes E01000 to E01051 in E-TUBE PROJECT
  • Do not attempt this professional task: Inspect drive unit wiring or replace the drive unit with genuine parts

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Read five-digit subcodes E01000 to E01051 in E-TUBE PROJECT

    What they doThe dealer connects the bicycle to a PC using the Shimano SM-PCE1 or SM-PCE02 linkage device (plus SM-JC40 or SM-JC41 if no port is free) to run E-TUBE PROJECT Professional.

    They must show youthe E-TUBE PROJECT diagnostic screen showing the exact five-digit subcode and current firmware versions.

    In writingthe recorded subcode, any firmware update applied, and the diagnostic test result.

  2. Inspect drive unit wiring or replace the drive unit with genuine parts

    What they doIf E010 persists after resetting and updating firmware, the authorized workshop inspects the wiring to the drive unit (such as DU-E8000 or DU-E7000) and replaces the drive unit with a genuine Shimano unit if an internal fault is confirmed.

    They must show youthe inspected harness or the part number of the genuine Shimano replacement drive unit fitted.

    In writingthe root cause confirmed, the replacement unit serial number, and the warranty terms.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Stop riding safely and confirm the code on the display

    No special tools

    Who:
    you, with the bicycle stopped in a safe spot.
    How:
    pull over as soon as pedal assist stops and check the cycle computer screen (SC-E8000, SC-E7000, SC-E6100, or SC-E6010) or the EW-EN100 junction, where an error makes both LEDs flash red quickly at the same time.
    Result that matters:
    confirming that the full-screen alert is E010.
    If the screen shows E010:
    proceed to the battery button reset.
    If a different E-series or W-series code appears:
    check the Shimano manual table for that code.
    Evidence to keep:
    clear photo of the cycle computer showing E010.

  2. Turn the battery power off and back on again

    No special tools

    Who:
    you, with both feet off the pedals.
    How:
    press the power button on the battery to switch the system off, wait a few seconds with the bicycle stationary and no weight on the cranks, and press the battery power button again to turn it back on, as instructed in the Shimano manuals.
    Result that matters:
    checking whether the display clears and pedal assistance returns.
    If E010 clears and assist works normally:
    test gently on flat ground.
    If E010 remains on the screen:
    try the second reset method by detaching the battery.
    Evidence to keep:
    short video or note of the screen behavior after pressing the battery power button.

  3. Remove the battery from the holder and reinstall it dry

    No special tools

    Who:
    you, using the battery mount key.
    How:
    turn off the power, unlock the battery with its key, and remove it while supporting it firmly with your hand; verify there is no water or dirt in the mount connector, lock the battery back in place, and turn the power on.
    Result that matters:
    completing the second full-screen error reset procedure specified by Shimano.
    If the error disappears after reseating the battery:
    monitor the bike on upcoming rides.
    If E010 still does not clear after turning power back on:
    stop riding with assist and contact an authorized dealer.
    Evidence to keep:
    photo of the clean battery connector and the cycle computer after rebooting.

What it means

Shimano's official error table on si.shimano.com defines E010 as an abnormality detected in the drive unit, while the E8000 Series (UM-72F0B-001, DM-E8000-10) and E7000 Series (UM-79E0B-000) manuals list it as a system error under which power assistance is not provided during riding. In E-TUBE PROJECT Professional, Shimano breaks E010 down into five-digit subcodes (E01000 to E01051) pointing to internal drive unit sensors or the drive unit motor. Other model families may differ in detail, and seeing E010 alone never proves the drive unit is defective before resetting and running a diagnostic check.

  • Internal drive unit motor malfunctionLess common

    According to Shimano's official error reference, subcodes E01040 to E01042 under the E010 family indicate a malfunction detected in the drive unit motor itself.
