Caution / Notice / Hint

NOTE:
  • The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly.

    Refer to HOW TO PROCEED WITH TROUBLESHOOTING [12/2021 - ]

  • If the front power window regulator motor assembly LH has been replaced with a new one, initialize the power window control system.

    Refer to INITIALIZATION [12/2021 - ]

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

    Refer to CUSTOMIZE PARAMETERS [12/2021 - ]

  • 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.

HINT: 

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 power window master switch assembly with bezel at the auto up position, and opened manually by pushing down the power window master switch assembly with bezel.

Refer to FAIL-SAFE CHART [12/2021 - ]
