If the one-touch (auto) function on your Daihatsu Terios (J2, 2006–2017) has stopped working — usually after a battery disconnection or a flat battery — the driver’s window just needs re-initialising. It’s a quick job with no tools, and it is not a fault with the motor or the switch. The window is simply running in its basic manual mode until you teach the control module where the top and bottom of the glass travel are again.
Why the Auto Function Drops Out
The power-window motor on the Terios has a small controller that counts the glass position and stores the fully-up and fully-down limits. That memory is what makes the one-touch lift work and what powers the anti-pinch protection — the feature that stops and reverses the glass if it meets an obstruction on the way up. When the 12 V battery is disconnected, replaced, or allowed to go flat, that stored position is lost. The window still raises and lowers normally, but only while you hold the switch. Auto operation stays disabled until the module is shown the full sweep of travel once more. This is completely normal after any battery work and is not a sign that anything is broken.
Getting Ready
- Make sure the 12 V battery is fully connected and holding charge — the calibration will not stick on a weak battery.
- Sit in the driver’s seat and close the door so the glass runs cleanly in its channel.
- Turn the ignition on (engine running or in the on position).
- Clear the top of the door frame of anything that could block the glass, and check the rubber run channel is free of grit or ice.
Re-initialising the Window
- Turn the ignition on and close the door.
- Raise the window fully with the switch and keep holding briefly after it stops.
- Lower the window fully and keep holding briefly after it stops.
- Raise it fully again — the auto function should now work.
If It Still Won’t Work
- Hold at each limit for a full moment after the window stops — releasing the switch too early leaves the travel only partly learned.
- Do the whole sequence in one go without pausing; an interrupted run may not register.
- Re-seat the battery connections if you’ve just done battery work, then repeat the procedure.
- Check the relevant fuse if the window is completely dead — a blown power-window fuse leaves it lifeless rather than just manual.
- Let a fully flat battery charge properly first; a low voltage can prevent the memory from being written.
- A motor or switch fault can store a code — look it up on autodtcs.com.
What Happens Next
Once the sequence takes, a single tap on the switch will run the window all the way up or down on its own, and the anti-pinch protection is active again. The setting is stored, so it stays put until the next time the battery is disconnected. If you replace the battery again in future, simply repeat the same four steps.
Frequently Asked Questions
Why did my Terios auto window stop working?
Disconnecting or flattening the 12 V battery wipes the window controller’s stored travel limits, so it drops back to plain manual operation. Re-initialising it by running the glass fully up, fully down, and up again teaches the module the limits and restores the one-touch auto function.
Do I need a tool?
No. The whole job is done with the window switch on the driver’s door. There is nothing to plug in and no menu to open — you are simply cycling the glass through its full travel so the controller can re-learn the top and bottom positions.
Which window has the auto function?
On most Terios models the one-touch feature is on the driver’s window only. Re-initialise whichever window has the auto lift. If a window only ever moved while you held the switch, it never had the feature and does not need calibrating.
What does holding at the limit do?
Keeping the switch pressed for a moment after the glass reaches the top or bottom tells the controller that is the true end of travel. That reference is what the anti-pinch system and the one-touch lift both rely on, so a clean hold at each limit is the key to the reset working.
Do I have to reconnect anything first?
Only make sure the battery is properly connected and charged. A loose terminal or a battery still recovering from being flat can stop the calibration from saving, which is why the auto function sometimes fails to return on the first try after battery work.
Could the anti-pinch also be affected?
Yes. The same lost memory disables the automatic reverse-on-obstruction protection. Running the full re-initialisation sequence restores both the one-touch lift and the anti-pinch safety feature together, so you should not treat them as separate jobs.
