If the one-touch (auto up/down) function on your Aiways U5 (2020–2024) has stopped working — usually after the 12 V battery was disconnected or went flat — the windows just need re-initialising. It’s a quick job with no tools.
When You Need This
- After disconnecting or replacing the 12 V battery.
- If a window only moves while you hold the switch and won’t auto-close or auto-open.
Re-initialising Each Window
- Power the car on and close the door.
- Raise the window fully with the switch and keep holding for a couple of seconds after it stops.
- Lower the window fully and keep holding for a couple of seconds after it stops.
- Raise it fully again — one-touch should now work. Repeat for each window.
If It Still Won’t Work
- Hold at each limit for the full couple of seconds.
- Re-seat the 12 V battery connections if you’ve just done battery work.
- A motor or switch fault can store a code — look it up on autodtcs.com.
Frequently Asked Questions
Why did my Aiways U5 windows stop auto-closing?
Disconnecting the 12 V battery wipes the window calibration — re-initialise each one.
Do I need a tool?
No — it’s done with the window switches alone.
Do I have to do all the windows?
Yes — each window is calibrated separately.
What does holding at the limit do?
It teaches the module the full travel, restoring one-touch (and anti-trap) operation.
If the windows still won’t calibrate, decode any stored code on autodtcs.com.
