Slide Open 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 closed (limit SW No. 1 off, limit SW No. 2 on), the moon roof control SW is kept pressed to OPEN position for approximately 0.3 seconds or longer, as 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 open the moon roof automatically. Then, when the limit SW No. 1 is turned on and then turned off again, the pulse signal sent from the HALL IC activates the relay, and if the pulse signal is not input for 0.5 seconds or longer, it determines that the moon roof is fully open, and stops the motor. If other operation SW to the open SW is operated while the moon roof is being opened, the relay is activated to stop the moon roof operation. In addition, when the moon roof is tilted up, the slide open operation does not function.
