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

    Click here

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

  • 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 front power window regulator motor assembly LH 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 multiplex network master switch assembly at the auto up position, and opened manually by pushing down the multiplex network master switch assembly.
