Anti-Pinch Function Note (For Motors)

If your vehicle uses a motor with anti-pinch and one-touch function, correct setup is essential. Do not test the motor before it is installed in the door, as the anti-pinch function may lose calibration and require resetting.

Anti-Pinch Reset Procedure

• Step 1: Pull the window switch briefly so the window moves up slightly to the top position.
• Step 2: Hold the one-touch switch up for 3–5 seconds at the top.
• Step 3: Press the window switch briefly so the window moves down slightly to the bottom position.
• Step 4: Hold the one-touch switch down for 3–5 seconds at the bottom.
• Step 5: Pull the one-touch switch so the window moves up to the top.

The reset is complete if the window remains at the top and does not drop back down. If it drops, repeat the steps until the function is correctly calibrated.
