Reinitialization Description

If the driver side power window regulator assembly has been replaced or reassembled, it must be reprogrammed once in the order for the safety function to operate properly. This can be done by operating the driver side window switch. If the reprogramming procedure is not performed, the driver side window will not close automatically.

Reinitialization Procedures

  1. Press the driver side window switch until the window is under 100 mm (4.0 in) from the top of the window frame.
  2. Pull the driver side window switch to the first step of the UP position and hold until the window is fully UP.
  3. Important: Do not put the window switch to the second step of the UP position.

  4. Continue holding the window switch for approximately 3 seconds after the window motor stall. The driver side window motor assembly is now programmed for the safety function.
  5. Confirm the reprogramming procedure by performing the auto-up operation.
