Tilt Down Operation
WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
When the moon roof is fully tilted up (limit SW No. 1 on, limit SW No. 2 on), and the moon roof control SW is kept pressed to DOWN position for approximately 0.3 seconds or longer, a signal is input from TERMINAL 8 of the moon roof control SW to TERMINAL 9 of the moon roof control ECU. This activates the relay and rotates the motor to tilt down the moon roof automatically. Then, when the limit SW No. 1 is turned off, the pulse signal sent from the HALL IC activates the relay, and determines that the moon roof is closed fully, and stops the motor. If other operation SW or the tilt down SW is operated while the moon roof is being tilted down, the relay is activated to stop the moon roof operation.
