        (Windshield Wiper Switch Assembly)

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Front Wiper Switch
        Tester Connection Switch Condition Specified Condition
        I32-3 (+1) - I32-1 (+S) OFF Below 1 Ω
        I32-3 (+1) - I32-2 (+B) MIST
        LO
        I32-2 (+B) - I32-4 (+2) HI
        I32-8 (AUTO) - I32-9 (E) AUTO
        Front Washer Switch
        Tester Connection Switch Condition Specified Condition
        I31-4 (EW) - I31-7 (WF) ON Below 1 Ω
        OFF 10 kΩ or higher
        Adjusting Ring*
        Tester Connection Switch Condition Specified Condition
        I32-7 (VR1) - I32-6 (VR2) P1 209 to 231 Ω
        P2 114 to 126 Ω
        P3 58.9 to 65.1 Ω
        P4 Below 1 Ω

        Tech Tips

        *: The rain sensor sensitivity can be adjusted by the windshield wiper switch adjusting ring.

        If the result is not as specified, replace the windshield wiper switch assembly.
