If the one-touch (auto up/down) function on your Isuzu D-Max (TF, 2012–2020) 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.
When You Need This
- After disconnecting or replacing the 12 V battery.
- If the window only moves while you hold the switch and won’t auto-close or auto-open.
Re-initialising the Window
- 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 — one-touch should now work. Repeat for any other window with the feature.
If It Still Won’t Work
- Hold at each limit for a moment after the window stops.
- Re-seat the 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 D-Max auto window stop working?
Disconnecting the battery wipes the window calibration — re-initialise it.
Do I need a tool?
No — it’s done with the window switch alone.
Which window has one-touch?
Usually the driver’s; re-initialise any window that has the auto function.
What does holding at the limit do?
It teaches the module the full travel, restoring one-touch operation.
If you’ve just reconnected the battery, see our D-Max battery guide.
