Toyota Sienna Service Manual: Power Window cannot be Operated by Wireless Operation
DESCRIPTION
When the switch on the transmitter is operated during normal operating conditions, the multiplex network body ECU sends a request signal to the master switch and the regulator switches which then drive the applicable power window motors.
INSPECTION PROCEDURE
1 CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
- Check that the wireless door lock functions operate with movement of the transmitter switch.
HINT: When the wireless door LOCK/UNLOCK operation can be performed, it means that the wireless signal from the transmitter is properly input to the multiplex network body ECU.
2 CHECK MANUAL UP/DOWN FUNCTION
- Check that the manual UP/DOWN function using the master switch and each regulator switch can operate all the power windows.
3 CHECK REMOTE UP/DOWN FUNCTION
- Check that the remote UP/DOWN function using the master switch can operate the power windows.
