Wiper Switch (HI Speed) Circuit: Description

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

The main body ECU LH (cowl side junction block LH) receives a HI position signal from the windshield wiper switch assembly to operate the wiper motor at high speed.

Even if the ECU malfunctions, this circuit structure enables it to operate the wiper in HI operation mode.
