Can the E-Tube Project mobile app fully diagnose E010?

The mobile app shows E010 and allows firmware updates, but cannot read sub-error codes that identify which specific internal component has failed. For persistent E010, the dealer PC software is required for full diagnosis.

Does E010 mean my motor is dead?

Not necessarily. Many E010 cases are firmware-related and clear after an update. Hardware-confirmed E010 (persistent after firmware update) typically requires motor replacement, but this is often covered under the Shimano 2-year drive unit warranty.

Shimano STEPS Error E010: Motor System Fault Fix

What Error E010 Means

Error E010 on Shimano STEPS systems is a broad drive unit fault code — the motor controller has detected a malfunction within its own electronics or sensors that it cannot attribute to a more specific component. Motor assistance is fully disabled when E010 is active.

E010 covers a range of internal conditions including motor controller communication failures, internal sensor faults, and firmware assertion errors. Because it is a broad code, self-diagnosis is limited — but several common causes can be eliminated before visiting a dealer.

Self-Checks

Step 1: Full Power Cycle

Turn the system off completely. Remove the battery for 30 seconds. Reinstall and power on without touching the pedals. E010 caused by transient firmware errors or power supply glitches often clears after a full reset.

Step 2: Check Firmware via E-Tube Project App

Connect the Shimano E-Tube Project app (available for iOS and Android) via Bluetooth to your bike. The app displays the firmware version on all components and flags pending updates. Apply any available drive unit firmware updates — known E010-triggering firmware bugs have been patched in multiple EP8 firmware releases.

Step 3: Inspect All External Connectors

Check the motor cable connector, display connector, battery contacts, and any brake sensor connectors. Clean and firmly reseat each one. A faulty external connector feeding corrupted signals into the motor controller can produce E010 as an internal fault flag.

Step 4: Check Brake Sensors

Shimano STEPS uses magnetic brake sensors that cut motor output when brakes are applied. A faulty or permanently-triggered brake sensor can cause the controller to log internal faults. Disconnect brake sensors one at a time and test if E010 clears.

Dealer Diagnosis

Persistent E010 requires the Shimano E-Tube Project diagnostic software for PC and a dealer-grade diagnostic cable. The PC software can read sub-error codes that the mobile app does not display, identifying the specific internal component that has failed. Most E010 hardware faults result in drive unit replacement.
