CAUTION / NOTICE / HINT

Note


  • Inspect the fuses for circuits related to this system before performing the following procedure.

  • 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.

  • When the ECU determines that the front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD) has a malfunction, DTC B2311 is stored.

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