POWER WINDOW CONTROL SYSTEM - Front Passenger Side Power Window Auto Up / Down Function does not Operate with Front Passenger Side Power Window Switch |
DESCRIPTION
If the manual up and down function operates normally but the auto up and down function does not, then fail-safe mode may be functioning.If power window initialization has not been performed, the auto up and down function will not operate (LandCruiser RM0000011V20BLX.html).
WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- If the front power window regulator motor assembly RH (for LHD) or front power window regulator motor assembly LH (for RHD) has been replaced with a new one, initialize the power window control system (LandCruiser RM0000011V20BLX.html).
- Check that the "P Window Auto Up" and "P 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 (LandCruiser RM000005CF7003X.html).
- 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 (LandCruiser RM000000PY206VX.html).
- HINT:
- If the pulse sensor built into the front power window regulator motor assembly RH (for LHD) or front 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 (LandCruiser RM000000X8Z0DCX.html).
