Rear Wiper Intermittent Function
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 ignition is on and the rear wiper and washer switch is turned to INT position, a signal is input to TERMINAL RWCI of the body ECU. As a result, the body ECU controls wiper motor operation time, and operates the wiper intermittently. See WIRING DIAGRAMS .
