Shimano STEPS Error Code E022 (Battery Not to System Standards): Meaning + Next Steps
TL;DR
E022 = Battery connected to the drive unit does not conform to system standards; system may not start.
Official next step: Restart (battery power) and consult an agency/dealer.
Quick fix (safe DIY first)
- Power off and re-seat the battery firmly.
- Restart the system using the battery power switch/button.
- If it persists, stop DIY—this usually needs dealer verification of battery/firmware/compatibility.
60-second checks (the things that cause repeat codes)
- Any visible damage to battery casing, contacts, or mount?
- Did it start after aftermarket electrical work (lights, charger, display swap)?
What usually causes E022
- Loose or intermittent connectors (battery mount, motor harness, display/switch).
- Water/corrosion at contacts after rain/washing.
- Firmware/compatibility mismatch after service or a component swap.
- In some cases, an internal sensor or control-unit fault that needs dealer diagnostics.
When to stop DIY (go to a Shimano STEPS dealer)
Go to a dealer if:
– The code returns immediately after a clean restart.
– Assistance cuts in/out while riding (safety issue).
– You see damaged wiring, bent pins, corrosion, or water intrusion.
– The official remedy for the code is “consult an agency/dealer.”
Don’t do this
- Avoid using unknown third-party batteries or wiring modifications.
