Anti-Pinch Function Reset (For Motors with One-Touch)

If used with an electric motor featuring anti-pinch and one-touch function, a reset may be required after installation.

• Install the motor and connect it to the one-touch window switch before testing.
• If the window drops down after reaching the top position, follow the reset steps below.

Reset procedure:

• Step 1: Pull the window switch briefly to move the window fully up to the top.
• Step 2: Hold the switch in the up position for 3–5 seconds at the top.
• Step 3: Press the window switch briefly to move the window fully down to the bottom.
• Step 4: Hold the switch in the down position for 3–5 seconds at the bottom.
• Step 5: Pull the one-touch switch to move the window up to the top and check that it no longer drops.

If the window still moves down after reaching the top, repeat the steps until the anti-pinch function is correctly set.

Installation & Notes

• Professional installation by a qualified automotive mechanic is strongly recommended.
• Intended for the repair and replacement of an existing faulty window regulator.
