CAUTION / NOTICE / HINT

Note


  • If the power window regulator motor assembly RH (for LHD) or power window regulator motor assembly LH (for RHD) has been replaced with a new one, initialize the power window control system.

    Click here

  • Check that the "P Window Auto Up" and "P Window Auto Down" power window control system customize settings are "ON" before proceeding with work.

    Click here

  • After the catch protection function operates, the auto operation is not performed the first time auto up is performed. All auto up operations performed after the first operate normally.

Tech Tips

If the pulse sensor built into the power window regulator motor assembly RH (for LHD) or power window regulator motor assembly LH (for RHD) is malfunctioning, the power window control system enters fail-safe mode. The remote up and down and auto up and down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator switch assembly at the auto up position, and opened manually by pushing down the power window regulator switch assembly.
