Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch |
DESCRIPTION
If the manual up/down function can be performed but the auto up/down function cannot, then the fail-safe mode may be functioning.
If the power window initialization (See page
![2016 - 2020 MY Sienna [12/2015 - ]; WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: INITIALIZATION](/t3Portal/stylegraphics/info.gif)
) has not been performed, the auto up/down function will not operate.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
-
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 (See page
).
-
If the front power window regulator motor assembly LH has been replaced with a new one, initialize the power window control system (See page
).
-
Check that the "D Window Auto Up" and "D Window Auto Down" power window control system customize settings are "ON" before proceeding with work (See page
).
- 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 RH 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 (See page
).
